What about sea food?!
Dietary strategies of Pleistocene Pongo sp. and Homo erectus on Java (Indonesia)

Kudu runner asked:
What about sea food?!
??
Don't you even know, my little boy, that aquatic food (necessary for erectus' brain elnlargement) is "less dependent on variations in seasonal resource availability"??
How much sea food do elephants eat? Their brain is 3 to 4
times bigger than a human brain.

Dietary strategies of Pleistocene Pongo sp. and Homo erectus on Java (Indonesia)

Early to mid-Pleistocene Java was inhabited by hominid taxa of great diversity,
but their seasonal dietary strategies have never been explored.
We undertook geo-chemical analyses of Pongo sp., H.erectus & other mammalian Pleistocene teeth from Sangiran.
We reconstructed past dietary strategies at subweekly resolution, and inferred seasonal ecological patterns.
Histologically controlled spatially resolved elemental analyses (laser-based plasma mass spectrometry) confirmed the preservation of authentic biogenic signals, despite the effect of spatially restricted diagenetic overprint.
The Sr/Ca record of faunal remains is in line with expected trophic positions, contextualizing fossil hominid diet.
- Pongo sp. displays marked seasonal cycles:
~3 month-long strongly elevated Sr/Ca-peaks, reflecting contrasting plant food consumption (monsoon season?),
lower Sr/Ca ratios suggest different food availability during the dry season. - In contrast, omnivorous H.erectus shows low & less accentuated intra-annual Sr/Ca-variability vs Pongo sp.:
d13C data of 1 individual indicate a dietary shift from C4 to a mix of C3 & C4 plants.
Our data suggest: H.erectus on Java was
- maximizing the resources available in more open mosaic habitats,
- less dependent on variations in seasonal resource availability.
While still influenced by seasonal food availability, we infer:
H.erectus was affected to a lesser degree than Pongo sp., which inhabited monsoonal rain-forests on Java.
We suggest:
H.erectus maintained a greater degree of nutritional independence by exploiting the regional diversity of food resources across the seasons.
Very interesting article.
It shows that H.erectus probably had a lot of plant food (incl. seaweed?) in their diet:
IOW, only incredible idiots believe their ancestors ran after kudus.
The shift from C4 to C3+C4 confirms that H.erectus (probaby *at least* early-Pleist.) had shellfish in their diet:
- shell engravings, google "Joordens Munro",
- stone tools = opening shellfish cf. sea-otter,
- brain size x2 vs apiths-apes, cf.DHA in seafoods,
- pachyosteosclerosis only seen in shallow-diving tetrapods,
- island colonizations, e.g. Flores,
- intercontinental dispersal (+ mid-Pleist. H.neand. seasonally along Rhine, Meuse...),
- etc. = coastal dispersal hypothesis.
Google "human evolution Verhaegen" :-)
Only incredible imbeciles still believe their Plio-Pleistocene ancestors ran over hot savannas.
How long will these idiots still write their nonsense??
The really interesting questions are:
why do many?most aquatic mammals evolve rel.large brains?
- abundance of brain-specific nutrients in aq.foods? only *sea*food? DHA, iodine etc.
- less mobile heads/necks in swimming?
- less carrying costs: density of water?
- complex evol.histories?
- ...?
- how can some people be so stupid that they believe they descend from savanna animals??
Savanna animals have to be fast & mobile: they need rel.small heads+brains: IOW, only incredibly idiots believe they descend from kudu runners.

Only the stupid would claim "aquatic food (necessary for
erectus' brain elnlargement)". By the just so story approach of
AA, an elephant must eat sea food.

Amongst the incredibly stupid things you've said, this must rank amongst
the stupidest, if not holder of the title of absolute stupidest...
We know human brains require DHA and we know we're not very good at synthesizing it and we know that the genetic mutation that helps us to synthesizing it is *Way* younger than erectus or even what you nimrods
call "Anatomically Modern Humans."
Also we know that Homo exists outside of Africa.
For real. Homo exists outside of Africa AND has existed outside of Africa
for millions of years.
EVERYONE accepts that Homo spread across the world via "Coastal
Dispersal." This is another name for "Aquatic Ape" -- Homo on water's
edge, exploiting marine resources, following the coast..
And, finally, you have never ever made any "Argument" about elephants
apart from claiming that there is an argument to be made... without you
ever making it.
Are elephant brains as dependent upon DHA as our own?
Are elephants as poor at synthesizing it?
AND THEN there's the fact that the elephant brain is SIGNIFICANTLY
smaller than is the humans, if we want to say that size is in proportion
to total body volume or wood by weight...
But that's you! You say incredibly stupid things that sometimes
/Sound/ good to the intellectually lazy or challenged... people who
don't understand the issue or what matters here... your comments can
only fool the ignorant, stupid, emotionally disturbed... well, that's about it.
Like this stupid "Elephant" thing.
You can use it to sway a moron, sure, but at the expense of making anyone with critical thinking skills see you are a goddamn idiot.
