You *$*%?#@! Neanderthal

There are some things that one knows instinctively. All the signals are there. We see them, they remind us of something and we wrack our brains to try to recall what they could conceivably mean. And then it hits: of course, that subliminal nudge really does not need scientific evidence because anyone with an iota of recall would remember the physical traits and match them up.

There are certain people among us who clearly have inherited questionable DNA.Secretly we think, wow, doesn't he look like a troglodyte?
  • Amazing, his loping, side-leaning walk.
  • Incredible what a sloven that woman is.
  • How could people be so utterly without morals?
  • And the prevalence of anti-social types lurking without society.
  • Not to mention all those psychopaths with not one shred of decency, incapable of feeling empathy for others, intent on sowing destruction wherever they pass....
Those are - we've always felt certain, though not all that certain as to voice it very often - the remnants of a primitive society that once stalked the Earth. Alongside homo sapiens. That's us, homo sapiens sapiens. "Man the wise", remember? Somehow, on the way to modernity,which is to say time approximating the current era, some of us mingled - ahem - with some of them.

Know what I mean? Damn well you know, you silly arse - get that innocent look off your face!

Seems, if you don't believe me, that scientists with the Max Planck Institute for Evolutionary Anthropology have conducted studies, extracting the DNA from very elderly bones. Bone fragments in fact, that they deduce represent three female Neanderthals, the youngest of whom would have lived 38,000 years ago. In Croatia.

These scientists led by Svante Paabo, have managed to sequence the Neanderthal genome using those primal bones. Neanderthals, we're reminded, lived alongside homo sapiens for quite a long while. It has always been suspected that there might have been some interbreeding. But here's a little secret: it wasn't us female homo sapiens that bore bi-racial babies.

The thing of it is we mightn't have been able to, since Neanderthals were unlike homo sapiens in some fundamental ways. Heavier-built, more muscular, with bony brow ridges - and larger brains. Translated, that means that a Neanderthal female would have been able to pass a newborn through her vaginal tract far more ably than homo sapiens females, more slightly built.

When the Max Planck Institute scientists extracted the DNA and subjected it to enquiry they were able to account for 60%of the Neanderthal genome, more than enough to be compared with the genomes of modern humans of European, Asian and African origin. And discovered what any alert judge of human form and character could have told them: we've a lot in common.

Obviously, some of us far more than others. Neanderthals may have left without leaving much of a trace about 30,000 years ago, but they live on. In us. In people of non-African ancestry, in any event. The conjugal relations appear to have taken place once humans left the African continent for Europe.

The findings point to "One to four percent of the DNA that I carry in my cells, if I come from outside Africa, is from the Neanderthals", according to Dr. Paabo. Considering the millennia upon millennia since then, he means not only himself, but you and me and everyone else. This is our inheritance.

You troglodyte.
