Manga Girls Beware: Extra Large Eyes Caused Neanderthal's Demise

Posted by Unknown on from the four-eyes-stays-alive dept.

An anonymous reader writes "The BBC reports on a new study of prehistoric skulls which suggests that Neanderthals became extinct because they had larger eyes than our species. As a consequence of having extra sized eyes, an average 6 millimeters larger in radius, more of their backside brain volume was devoted to seeing, at the expense of frontal lobe high-level processing of information and emotions. This difference affected their ability to innovate and socialize the way we, modern people (Homo Sapiens Sapiens) do. When the last Ice Age set on 28,000 years ago, Neanderthals had no sewn clothes and no large organized groups to rely on each other, hastening their fall. Yet, they were not stupid, brutish creatures as portrayed in Hollywood films, they were very, very smart, but not quite in the same league as the Homo Sapiens of Cromagnon."

    Personally, I'm more partial to the theory that we *are* Neanderthals (hybrids) and that they didn't 'die out', but were simply bred away.

    There has been little hard evidence that Neanderthals were any less intelligent than Sapiens, just less evidence found for their intelligence, likely because there were far fewer of them. Studies of their flint knapping abilities show they were at least as skilled at toolmaking as Sapiens.

    Anyhow, the article reads ore like a daydream than a piece on science, as evidence for the most important part (percent usage of the brain for eyesight, and the retardation effects of this difference)are omitted.

      Yeah, no kidding. My first response was, "what the fuck?" This is (seemingly typical) bad science.

      I'm sorry, there's more than 10mm variability in eye size in existing populations. That variability is kind of how you get stereotypes and things like manga in the first place. Not only that, but extrapolating "they didn't have mental capacity because they had larger eyes" doesn't even begin to follow, logically. Maybe their visual cortex was the same size? Maybe it was actually smaller and significantly more efficient, allowing them to actually process more of what they saw (unlike us, who ignore most of it)? Maybe, just maybe, they used more of their brains - which were actually bigger, despite the "they were stupid by modern standards" stereotypes.

      Pretty tiring. It's pretty irritating to see the "science" out of these types.

      In certain ways, yes. Chimps are known to torture other chimps, and ape packs are known to go after other packs of the same species and try to kill them all off.

    I thought it was already proven that Europeans are the ancestors of Neanderthals through DNA sequencing? And it's this very DNA responsible for a strong immune system in people with large amounts of Neanderthal DNA.

    Yep. From the article:

    Ms Pearce found that Neanderthals had significantly larger eye sockets - by an average of 6mm from top to bottom.

    From the summary:

    Now that cloning may have been perfected, we just need an “extremely adventurous female human” to carry a cloned Neanderthal baby.

    Wild enough?

    And from the departement of wild speculations we have the following gem...

    There is a way to test this hypothesis. There is a variation in eyeballs size among modern humans. If this hypothesis is correct, people with bigger eyeballs should be dumber. So get a random sample of people, measure their eyeballs, give them an IQ test, and see if there is any correlation.
