    Seriously…how would YOU know?

    Laland’s been at this a while. I recall reading stuff by Jablonka in the
    late 90s. I have Jablonka and Lamb’s _Evolution in Four Dimensions_ from 2006. Almost 20 years ago published it was. Laland and Brown’s _Sense and Nonsense_ which was a pretty good book giving overviews on various fields
    like ev psych, memetics, and gene-culture coevolution was from 2002.

    Some of the stuff they push now is interesting, especially niche
    construction, but does it warrant rethinking evolution? Maybe the blinkered approach of old school Dawkins. But even his goofball redheaded stepchild memetics is in the mix with this EES polemics it seems.

    Gene-culture coevolution may be important in species having culture…humans. Lactase persistence in dairying cultures is a popular notion, but hardly a generalizable sort of thing for non-dairying species. Blessed are the cheesemakers.

    From your Nature link:
    “The number of biologists calling for change in how evolution is conceptualized is growing rapidly. Strong support comes from allied disciplines, particularly developmental biology, but also genomics, epigenetics, ecology and social science1,2.”. How broad a scope has social science compared to Hoxology? I guess social science could apply at least tangentially to viral evolution in humans.

    “In the decades since, evolutionary biology has incorporated developments consistent with the tenets of the modern synthesis. One such is ‘neutral theory’, which emphasizes random events in evolution. However, standard evolutionary theory (SET) largely retains the same assumptions as the
    original modern synthesis, which continues to channel how people think
    about evolution.”

    Yeah the uptake of neutral theory seems low to nil given the bullshit Larry Moran often contends with on his blog. So SET adaptationism seems quite allergic to it still.

    Developmental bias may have something going for it. Extragenetic
    inheritance seems to include as a subset stuff applying to cultural
    organisms (like humans) or where behavior is passed via a separate learning channel. Another subset called epigenetics is interesting but oversold. The effects (methylation or chromatin markers) are transient.

    I will grant “…also encompasses those structures and altered conditions that organisms leave to their descendants through their niche construction
    — from beavers’ dams to worm-processed soils.”

    But as far as behavioral driven evolution, say the first lobe-finned fish exploiting prey outside the water for instance, Jean Piaget was already thinking about that stuff long ago, though in terms put forth by James Mark Baldwin and Conrad Waddington. He got a little speculative with the possibilities the discovery of reverse transcription opened up. From his _Behavior and Evolution_: “As for the question of interactions between epigenesis and the genome, where I have endeavoured to stay within the
    bounds of a caution dictated by our ignorance, it remains to be seen
    whether or not the findings of Temin or others can lend support to the
    general orientation of my thesis.”

    Or: “Behaviour's role in the formative mechanisms of evolution was
    naturally re-interpreted in a more comprehensive fashion once it was
    realized that biological causality is never linear or atomistic in form,
    but always implies the operation of feedback systems as defined by the cyberneticians. The postulation of this mode of operation not only
    conferred a causal or mechanical character on teleology—it also meant that interactions had to be taken into consideration everywhere one-way
    causality had formerly been deemed an adequate explanatory model. But for a long time there was one case to which this general rethinking was not applied—namely, the process whereby DNA becomes RNA. For some reason,
    nobody questioned the idea that this process was unidirectional and irreversible. We know enough now, however, thanks to the work of Temin and others, to say that it may be reversed on occasion.”

    If you had read the nature opinion piece you would know that nothing
    much is going to change with respect to IDiots and other Biblical
    creationists. This just doesn't matter for creationists.

    Take their claims that there is more to inheritance than genes. We have
    known this since the beginning of the modern synthesis, before we knew
    what a gene was.

    Genes + environment = phenotype.

    Look it up. This has been known to be the case before we had the modern synthesis, before we knew what genes were. The opinion piece only wants
    to claim that the phenotypic changes due to environmental causes can aid natural selection. The equation doesn't have to change. The results
    will be the same. It has been known for a very long time that the environmental changes could broaden the range of phenotypes that you
    could get from any specific genotype. It is no surprise to anyone that
    if the phenotype can be bent towards something that allows a genotype to exploit some new resource or have some selective advantage in that
    environment that it can act as a temporary boost for that genotype, and
    that new mutations or resorting of existing variation with that genotype
    can result in the genome being better adapted to that environment. They
    aren't changing anything, they are just stating the obvious. The
    environment can influence phenotype. If an environmental influence
    changes the phenotype in such a way that, that specific genotype has
    some selective advantage in that environment, the genotype can be
    selected for in that environment. Other genetic variation can make the adaptation even better.

    It can be complex. A shift in temperature could cause a phenotypic
    change that better adapted the organism to living in a rocky area, so
    that genotype could be selected for in a rocky area under those
    temperature conditions. Add a few more genetic variants and you may no
    longer need the environmental boost to compete in that new environment.
    No matter how complex or whether or not the phenotypic change has some advantage in that environment, nothing changes in terms of what we know
    about how the environment affects phenotype.

    IDiots and other anti-evolution creationists are just out of luck on
    this one.

    Ultimately not a very interesting question, more a semantic
    convention that is of use mainly for historians of science. As the
    paper argues, one could also ask if neutral evolution and the
    recognition of drift already lead to something that should get its
    own name. As far as
    I can see, all the things the "new" synthesis would add are already
    done. Maybe not as much as some of its advocates would like, but
    that's merely an issue of emphasis and focus. And yes, it would be

    One might suggest that the basic idea of niche construction is
    implicit in Darwin's story of the bear skimming insects off a lake's
    surface.

    shush!! We don't talk about the whale-bear, ever, it's an ill omen.
    Yours most faithfully, Chas Lyell

    Did Lyell misunderstand Darwin's bear argument, the same way modern creationists do?

    I don't think so - rather, they exchanged several letters about this,
    and Lyell warned Darwin that this example was bound to be misunderstood. Darwin agreed in parts, which led to the reformulations it in later
    editions, but Darwin was adamant to keep it in some form - only
    later to regret it in a follow-up letter to Lyell, where he then
    used the term "ill omen"

    Going back to the real issue though, I'm not sure it's quite what they
    mean with niche construction - at least the way I understand them -
    because there is no feedback loop from the effect that the bear has on its environment and subsequent selection pressures. IIRC the example we got in school were beavers: they are adapted for semi-aquatic life, AND create
    more semi-aquatic environments through their building activity which then again acts on the beaver and increases the pressure on those less well adapted etc. Or humans. -NS is different in an environment with hospitals than one without

    And post-Darwin: In an environment with massive internet access
    we get a new form of natural selection by parents convincing each other
    that vaccination must be bad for the kiddies.

    It's just like beavers: stupidity creates more stupidity,

    Umberto Eco: "Social media gives the right to speak to legions of imbeciles who previously only spoke at the bar after a glass of wine,
    without damaging the community. They were immediately silenced, but now
    they have the same right to speak as a Nobel Prize winner. It’s the
    invasion of imbeciles."

    If you follow Quora (as I, against my better judgement, have been
    doing) you may get the impression that ignorance and stupidity are characteristic of the USA, but I don't think it is that. There may well
    be proportionately as many ignorant and stupid people (including
    crackpots of all kinds, such as creationists and religious nutters) in
    the UK, France or the Netherlands as in the USA, but they have less
    opportunity to shout about their ignorance and stupidity, and they are encouraged less by idiot politicians.

    I had viewed the term as less restrictive, such that any alteration of behavior in turn altering the selective environment experienced by the organism would count. Darwin leaves open the question of whether change
    in phenotype or of behavior comes first, but he also suggests mutual
    feedback between the two. My notion was that it's not the physical environment that counts but the environment as experienced by the
    organism. Thus a change of food source could count. That would certainly increase the impact of niche construction on evolution and greatly
    increase the number of examples, which would otherwise be fairly few.

    Evolution has a number of feedback loops - between species (arms races), between the two sexes of a species (sexual selection), between organisms
    and the environment (niche construction), ... It'd be nice to
    operationalise our understanding of these processes, but I doubt that
    rises to a new theory of evolution.

    25 years ago chaos was a hot topic, and Kauffman's research program had
    hopes of bringing self-organisation into the centre of evolutionary
    theory. That, if successful, would have, I think, been a bigger change.
