    There's a point to something JTEM said there: the fusion could have

    It's more than that, my honey bunches of oats. It's excessively unlikely
    that it happened all at once. In all probability it began as 47
    chromosomes and only later became 46. The belief is that it's *Oodles*
    easier to move from 48 to 47 and then 46, instead of from 48 to 46.

    Going from 48 to 47 isn't much of a barrier to breeding with all the 48 chromosome members of the group, for example. There's no reason why
    you can't have both members carrying 47 and 48 chromosomes in the
    same population.

    What you write above is factually correct. However, those facts don't
    inform when the chromosome 2 translocation happened. Using your
    words, it's excessively unlikely to have happened after LCA between
    H.sapiens and H.neanderthalensis, or before the LCA between chimpanzee
    and humans. It's remotely possible there were 46-chromosome
    neanderthals and chimpanzee ancestors, but those lineages must have
    gone extinct.

    The dating method is associated with the reduction in recombination rate
    due to the fusion event no longer being at the end of a chromosome.
    There are also the sequence rearrangements and insertion/deletions
    around the fusion site between chimps and humans. They could have
    occurred after the fusion back millions of years, but that would have
    further reduced the recombination rate between the fused and unfused chromosomes.

    It doesn't matter for JTEM. If it happened a long time ago or just
    recently it still happened and would still be the fusion of what are
    still two separate chromosomes in the other apes. Adam and Eve may not
    have had the chromosome fusion, but by the time Neanderthals and Modern
    Humans separated the fusion existed because Neanderthals also have the
    fusion site. The Reason to Believe creationists would claim that
    Neanderthals are a recreation that had the same chromosome fusion as
    Adam and Eve.

    The evidence for more than one deleterious step doesn't involve more
    than one fusion event because we only have evidence for one fusion
    event. There have been rearrangements and insertion/deletion changes in
    the region of the fusion event relative to chimps, but it isn't clear if
    they happened before or after the fusion event. You can't tell for
    sequence that is missing (deleted). There might have been a mutation
    that weakened one centromere of the two chromosomes involved so that,
    that chromosome may have had difficulty segregating properly, and would
    be deleterious in terms of dead embryos. The fusion event would have
    rescued that bad centromere by attaching it to a good centromere of
    another chromosome. This would have also aided in reducing the
    chromosomal anomalies due to segregation of the fused chromosome with
    two active centromeres.

    If you understood what they were measuring you would know that it
    doesn't matter about how long the fusion existed outside of some fixed population with only the fusion. There is a reduced recombination rate
    for the fusion region because it is no longer on the end of two
    chromosomes, and what does it matter if it could have happened a million
    years before it became a human signature differentiating it from the
    other apes. It would have still occurred, and eventually would
    differentiate our chromosome number from the other apes.

    Just because you don't want to understand the DNA evidence doesn't mean
    that no one can understand it. Behe and Denton are two ID perps that understand the DNA evidence well enough to agree that biological
    evolution is a fact of nature, and that it has to be considered in any intelligent design model. The Big Tent was always a lie that the ID
    perps propagated. Science is only the best means that we have for understanding nature (the creation) and there is only one nature to
    understand. Any ID science would have never supported the Big Tent encompassing all the various biblical creationist beliefs.

    To the best of my knowledge, Neanderthals did.

    If you had asked me five years ago I would have guessed a start with

    But having 47 chromosomes shouldn't be anywhere near as tough of an issue.
    The 47 offspring COULD breed. And when you've got people with 47 doing the slip-n-slide with others who have 47, THAT'S the most likely path to
    46.

    It's the model that works. Period.

    48 -> 47 -> 46

    The breeding issue is the, um, well it's the issue. But if you have multiple groups
    where the 47 is common enough, and they meet, they can start pushing out 46ers and maybe enough of them so that they don't have to worry about breeding restrictions.

    Two events aren't required, just one that increases in frequency.

    interbreeding in a state of equality.

    Why does there have to be two fusion events? Around 1 in 2,000
    individuals have some type of chromosome structural difference. They
    are called structural variants and include inversions and
    translocations. The event was a head to head fusion, so it wasn't a Robertsonian type of reciprocal translocation. Reciprocal
    translocations involving the large chromosomes result in half the
    gametes being unbalanced. Half the pregnancies result in dead embryos,
    usually early in development and they are very common with a lot of them segregating in the population right now. They aren't really noticed
    unless the transferred bits of chromosome are small and the embryo dies
    late in pregnancy. If there was segregation distortion related to the
    fused chromosome it wouldn't be any worse than the reciprocal
    translocations that are so common. If there was segregation distortion
    there would have been difficulty fixing the change in the population.
    It would most easily occur within small family bands. The ancient
    Neanderthal DNA indicates that there was inbreeding within the small
    family groups, but there was also migration where mostly females would
    transfer between groups. With a system like this you could fix the
    fusion in one small family group and it could be distributed to other
    family groups by transfer of females. You have to mate two carriers
    together before you can get progeny that have two copies of the fused chromosome.

    The facts are just the facts. The fusion obviously got fixed in the
    population ancestral to both modern humans and Neanderthals. It doesn't
    matter how unlikely the event is once it happens, and it happened
    800,000 years in the past. It could have been intelligent design, but
    the designer would have had to use an ape genomic template to create
    humans, and part of the design would have been fusing two ape
    chromosomes together to make one large chromosome.


    So, we could just be seeing the molecular dating of the dominant group,
    which could be more recent. That's all.

    The recent dominant group would have had to have the chromosome fusion
    or it would have been lost by replacement of the smaller group by the
    larger group. If the fusion was transferred from the smaller group to
    the larger group that would just extend the time that the fusion would segregate in a population, but wouldn't change the date of the original
    fusion. For that to matter you would have to demonstrate that the recombination rate was not decreased by the fusion event in populations
    with mixed chromosomal composition. The current paper under discussion
    used the reduction in recombination rate as their clock. If the
    recombination rate only decreased after fixation of the fusion in some population, it could extend the date of the fusion event further back
    into the past, but what good does that do creationists that don't want
    the fusion event to have ever occurred?

    evidence?


    Going from 48 to 47 shouldn't represent much of an issue, certainly less of an issue than going from 48 to 46. That 46 offspring is going to be dancing alone...

    Do you know what you are trying to claim? You should try again. There
    is no mystery about how you go from 48 to 46 chromosomes due to a
    chromosomal fusion. There are 22 pairs of autosomal chromosomes and 1
    pair of sex chromosomes (XX or XY) for humans. The other great apes
    have 48 chromosomes, 23 pairs of autosomes and one pair of sex
    chromosomes. When two of the autosomes fused together you have one
    chromosome where you used to have 2. This means that you can have the
    same genomic content but have one less pair of chromosomes, so adopting
    the fusion reduced the chromosome number for humans to 46 chromosomes.
    When the fusion was segregating there was no longer 23 pairs of ape
    autosomes. Carriers of the fusion would have 21 pairs of autosomes, the
    fusion chromosome, one 2p chromosme and one 2q chromosome. The 2p and
    2q chromosomes are no longer paired to individual 2p and 2q chromosomes
    so they exist has half pairs. This gives you the 47 chromosome count
    for individuals that have one copy of the fusion chromosome.
    Individuals in the population without the fusion would have 48
    chromosomes and individuals with only the fusion would have 46
    chromosomes, so individuals with 46, 47 and 48 chromosomes would
    naturally be segregating in the population. If carriers had segregation distortion issues carriers might have half their gametes defective when
    the mate with either 46 or 48 chromosome individuals, but there is no
    reduction in viable gametes when a 46 chromosome individual mates with
    an individual with 48 chromosomes. Such a pairing just produces all
    progeny with 47 chromosomes. When a 46 chromosome individual mates with
    a 47 chromosome individual half the progeny have 46 chromosomes and half
    have 47 chromosomes. But half the gametes of the 47 chromosome
    individual are not viable so it takes twice as many conceptions to
    produce the same number of progeny. For a species with a monthly
    menstural cycle this isn't much of a handicap.

    There is no mystery of how you go from 48 chromosomes to 46.


    But having 47 chromosomes shouldn't be anywhere near as tough of an issue. The 47 offspring COULD breed. And when you've got people with 47 doing the slip-n-slide with others who have 47, THAT'S the most likely path to
    46.

    It's the model that works. Period.

    48 -> 47 -> 46

    The breeding issue is the, um, well it's the issue. But if you have multiple groups
    where the 47 is common enough, and they meet, they can start pushing out 46ers
    and maybe enough of them so that they don't have to worry about breeding restrictions.

    There is no mystery of how you go from 48 chromosomes to 46. You need
    to rethink what you are trying to argue.

    Events of the type represented by the human chromosome 2 translocation

    in time and space to eventually merge to 46 chromosomes is possible,
    in the sense that the laws of physics allow it, but is extremely

    Snip and run from reality, but reality never changes. There was one,
    whether the designer did it or not.

    You didn't understand any of what you were given. It is just a fact
    that there was a chromosome fusion involving two ape chromosomes. There
    was one, not two or none. It doesn't matter whether the designer did it
    or not, there was obviously a chromosome fusion event. These things
    happen. Around 1 in 2000 people wandering around today have structural chromosomal mutations like translocations inversions and
    duplication/deletions. These things have already happened and they keep happening.


    I've argued many, Many, MANY times over the years that once
    you establish something has happened, you need a reason to
    stop it from happening or, by definition, it will happen again.

    The problem is that you can't keep it from happening. These types of
    mutations just happen on a regular basis. The only thing we can do is
    identify the issue and tell parents the odds of them having normal
    children after the events happen. If not enough of one chromosome was transferred to another in the translocation event babies can be born
    with severe defects. In the case of this chromosome fusion the aberrant segregation of chromosomes would have been lethal early in embryo
    development and the woman likely would not even know she was pregnant
    because the whole chromosomes were involved in the fusion. For
    translocations where only a piece of a chromosome is transferred there
    can be enough development to notice and these people have to be
    genetically advised of the possible outcomes of trying to have kids. We
    can now super ovulate the woman and produce multiple embryos and pick
    out the normal ones, so there is something positive that can be done
    after the fact.


    It did happen again... if it's possible and there is nothing stopping
    it.

    The only thing stopping it from happening again is that it has already happened. Such a chromosome fusion could still happen in chimps because
    they still have the two separate chromosomes.

    There's two points here. The first is this type of genetic burping
    isn't all that uncommon:

    https://www.nature.com/articles/jhg201080

    I mean, it's not like everyone undergoes a chromosome count, &
    a mapping, yet they do find these things all the time.

    Secondly, it's not about mutations it's about viability. If 47 pops
    up in an individual, they can still produce viable offspring. But if
    someone with 46 magicked up, successful breeding is unlikely at
    best.

    Seems to me that the best model for having a large enough
    population carrying 47 chromosomes so that offspring with 46
    can meet and successfully reproduce is if you start with two
    or more.

    For two of these rare events to happen sufficiently close
    in time and space to eventually merge to 46 chromosomes is possible,
    in the sense that the laws of physics allow it, but is extremely
    improbable, especially within small isolated populations.

    So let's delete the time requirement.

    If we are speaking of two or more populations, it's very unlikely
    that they interbred as equals. Just having one group larger than
    the other throws everything out of whack!

    That's all you need; a population difference. Such a mutation could
    have been floating around in Group-A for a million years, and present
    in Group-B for only 10k. But if Group-B is larger, it may be their DNA
    that gets passed down through the filter of time.

    The
    mechanism that you previously noted is far more probable and IIUC has
    been documented in other species; a single chromosome translocation in
    a population of individuals with N chromosomes, followed by the
    reproduction of multiple N-1 chromosome offspring, followed by pairs
    of N-1 chromosome individuals reproducing N-2 chromosome offspring.

    Yeah, well, there's more than one model. This is the norm. I don't see
    that as the best model. Given a reproductive rate that looks something
    like a rodent, sure. But start slowing things down, longer childhoods, fewer offspring and it doesn't look as hot.

    A lot of this depends on your assumptions, or overview. The more recent
    you make this happen, for example, the more like us in the present your starting population looks, and acts.

    Environment matters. If you subscribe to Aquatic Ape then you can
    support a larger population than a forest. And if Chimps are any
    indication, the forest can support a larger population than a savanna.

    Well, when sarcasm is your only tool, I suppose that's what you have to
    use. The fact is that (as Ron O. has tried to explain to you a few times
    now), the problem with chromosome fusions lies with meiosis in
    heterozygotes, in which there can be problems in forming gametes, though
    with only minor effects on fecundity. But that's exactly the "barrier to reproduction" you're talking about. It's the same barrier whether the heterozygote goes only to mate with an individual having 46, 47, or 48 chromosomes. The sole effect is during meiosis in gametogenesis.

    There is of course no such problem with homozygotes, regardless of
    whether they have 48 or 46 chromosomes. And mitosis is no difficulty at
    all. The result of a mating between 48-chromosome and 46-chromosome
    individuals would just be all 47-chromosome heterozygotes, with no
    reduced fecundity.

    That's the point. But offspring with 46 chromosomes is unlikely to have
    been able to reproduce with members of the population with 48. So we're talking about how it went from 48 to 46.

    What you have just snipped out and run from explained what happened when
    an individual with 46 chromosomes mated with one with the ancestral 48 chromosome individuals. Go up one post and find out for yourself that
    100% of the possible combinations are viable they all result in
    individuals with 47 chromosomes. When an individual with 47 chromosomes
    mates with one with the ancestral 48 chromosomes half the progeny born
    have 48 chromosomes and half have 47 chromosomes. When an individual
    with 47 chromosomes mates with an individual with 46 chromosomes half
    the progeny have 47 chromosomes and half have 46 chromosomes.

    The half of gametes that have an too much or too little of a chromosome
    cause early embryonic death, and the female likely never knew she was
    pregnant. This likely delays a successful pregnancy, but not by much
    because humans have a monthly menstrual cycle.

    That is one of the reasons you see claims that the fusion wasn't very deleterious. There are also cases where for some reason the chromosomes continue to pair properly and there isn't any segregation distortion and
    full complements of the affected chromosomes find their way into gametes
    so there doesn't seem to be much of any effect.


    The problem is that you can't keep it from happening.

    That's not the problem, no.

    The problem isn't that mutations happen. The problem is coming up with
    a model that best provides for a mutation coming to typify a population.

    No problem at all as you can see above. Just drift and founder effects
    would do it. It would have helped if the fusion was selected for, for
    some reason, but there wasn't much keeping the fusion from hanging
    around until it was fixed or not. There are claims that the fusion
    brought differnt genes in closer proximity on one chromosome and that
    might have been selected for due to the change in gene regulation.

    I see that you have snipped and run from what you can't deal with again.
    Just like any other mutation it gets fixed in the population. If
    there is a selective advantage the fixation is faster. If it is neutral fixation is literally the rate of mutation, but is affected by things
    like founder effects.

    What was keeping it from becoming the norm. What you snipped out would
    have told you that matings produced viable progeny. Your example of 46
    X 48 was no impediment. 100% of the gametes are viable and all progeny
    just have 47 chromosomes. For matings of 46 X 47 half the progeny have

    all created in an attempt to hide the fact that I only just now
    invented the idea.

    This seems like you are talking about yourself. Did you write this or
    was it one of your other personalities.

    Hmm.

    The estimated time of the fusion is around 800,000 years ago if you had
    read the paper that this thread is about. That was about the time the population that became Neanderthals and Denisovans were leaving Africa. Anatomically modern humans are found in the fossil record in Africa in sediments around 200,000 years old.

    The genome sequence we have of Neanderthals indicates that they had the chromosome fusion, so they seem to have taken it with them when they
    left Africa.

    I don't think you can claim that population that became Neanderthals
    were fixed for the chromosome fusion when they left Africa, but their descendants that became Neanderthals had the fusion 60,000 years ago.

    This topic reprises the same issues discussed in a recent SBP thread,

    human chromosome 2 fused, also date when various lineages diverged
    from modern humans. My understanding is none of those divergences
    correlate with that fusion event. This doesn't inform whether that

    Demonstrate that you did not snip and run to remain willfully ignorant.
    What happens when an individual with 46 chromosomes pairs with an
    individual with 48 chromosomes? Are any missegregation gametes produced
    by either individual? Are any pregnancies going to be prematurely
    terminated by the missegregation of chromosomes? How many chromosomes
    will all the progeny have?

    I don't buy into molecular dating at all. Are you claiming that they retrieved DNA from a fossil of 800,000 years in age or is your

    Willful ignorance is just a way of life for you. What was this thread
    about, and how could you have checked out what you want to remain
    willfully ignorant of?


    And dating is irrelevant anyways. Even if there were such a thing
    as molecular dating, it is just as likely telling us the most recent
    time a fusion occurred, not the first. Or it could be telling us the
    first -- we'd literally have no way of knowing. So it's irrelevant.

    We only have evidence of one fusion event creating human chromosome 2.
    You should read the two references provided in the first post of this
    thread. You can look up some of the old literature that predates the
    molecular work.

    This is cytological evidence from 1982. https://personal.broadinstitute.org/sfs/personal/Science-1982-Yunis-1525-30.pdf

    WIKI entry:
    https://en.wikipedia.org/wiki/Chromosome_2

    It probably wasn't the first fusion event in the human lineage, but for
    the creation of chromosome 2 it was the one fusion event that managed to
    be fixed in the population that became modern humans that resulted in
    the creation of chromosome 2 from what are still two separate
    chromosomes in the other great apes.


    Remember: You DO claim that such mutations are common! And
    that because they're so common it couldn't happen more than
    once... because that would require them to be common, which you
    say they are... and are not.

    Yes, they are common, but not many get fixed in the population. As I
    said around 1 in 2,000 people walking around have some type of
    chromosommal structural mutation. Pretty much all of them are only
    found in a few individuals of the extant population.


    Here. You in one of your many different mental states "Arguing"
    that it was too common to happen more than once:

    : These things happen. Around 1 in 2000 people wandering around
    : today have structural chromosomal mutations like translocations
    : inversions and duplication/deletions. These things have already
    : happened and they keep happening.

    Oo! And then there's your free-fall fantasy concerning the VAST
    internet conspiracy, as well as time travel. This is how I could invent
    the notion that the chromosome fusion could be a barrier to
    interbreeding -- and genetic wall of isolation -- right here and right
    now, AND there can be cites going back many years all talking
    about the same thing.

    What do you not get? Look up fixation rate of neutral mutations, and
    then think about the fact that most structural variants are not neutral
    and most have deleterious effects. The fusion was probably not that deleterious because half the gametes of carriers would be lethal, but
    the lethality occurs early in development, so it just means that half
    the conceptions would not lead to a normal pregnancy. Humans have a
    monthly menstrual cycle, so normal pregnancies would just be delayed.
    There is no segregation distortion for individuals that have 46
    chromosomes instead of the ancestral 48. You would understand that if
    you hadn't snipped and run from the information multiple times in this
    thread.


    Are you autistic? Is this why you see this black & white world where
    one answer is 10 hundred million percent correct and agreed upon,
    and the more common answer doesn't exist?

    You seem to be talking to yourself again. Do all your personalities

    human chromosome 2 translocation was responsible for creating
    H.sapiens. In fact, it had almost nothing to do with it.

    We don't actually know that. Conceivably, there's something about it
    that's important. But it does seem unlikely.

    I suppose you're right, if you mean "We don't actually know" in the
    same sense as "We weren't there".

    This topic reprises the same issues discussed in a recent SBP thread,
    which you also conveniently ignored. Similar methods which date when
    human chromosome 2 fused, also date when various lineages diverged
    from modern humans. My understanding is none of those divergences
    correlate with that fusion event. This doesn't inform whether that
    fusion event caused some feature we modern humans have, but biological isolation isn't one of them.

    There is ambiguity regarding what "H. sapiens" means. Some people still consider neandertals and denisovans "archaic H. sapiens". Biological
    isolation isn't really the question here.

    Ironically, you were agreeing with me, disagreeing with the alter. The Harpmen alter was claiming that, YES, of course it started with 47 and that this could have been before divergence:

    : And of course it started with 47. The fusion happened in some gamete and
    : the resulting individual was a heterozygote.

    : There's a point to something JTEM said there: the fusion could have
    : happened before separation of the chimp and human lineages, just not
    : having attained a high frequency in the population until later.

    But the beauty of being a highly disordered troll hiding behind sock puppets
    is that consistency is never an issue.

    Right?
