restricted to Africa....whereas Neandertal was restricted to Europe.

Quote:The human family tree just got another mysterious branch, an African "sister species" to the heavy-browed Neanderthals that once roamed Europe.

While no fossilized bones have been found from these enigmatic people, they did leave a calling card in present-day Africans: snippets of foreign DNA.

There's only way one that genetic material could have made it into modern human populations. "Geneticists like euphemisms, but we're talking about sex," said Joshua Akey of the University of Washington in Seattle, whose lab identified the foreign DNA in three groups of modern Africans.

This is incredibly interesting. I hope more evidence comes to light soon, so that we might see a more complete picture.

Thanks for ferreting this out. :3

The wording of the article does not inspire confidence that the arthor knows what he is talking about.

Too often the case. I'm sure there is more out there about it, though.

As stated it is published in Cell Journal.... the Spring edition of which includes such monumental topics as...

Quote:Evaluation of Preincubation Time Interval in Testicular
Biopsy to Obtain Optimum Sperm Parameters

The Summer issue is not even online yet.

They probably had the Publicity Department issue a press release that the Washington Post picked up and which was re-issued by the Star Tribune. It will take years for the scientific community to investigate.

You learn something everyday.

And seriously dolphins and whales can both have offspring!?

I wasn't aware of this, either. But I bet the offspring would be sterile.

Since dolphins are generally much smaller than whales, I would say copulation between a dolphin and a whale to be as logistically impossible as cross breeding between tigers and house cats.

I think the underlying grain of truth might be similar species of dolphins might mate amongst themselves, or similar species of whales might mate, but not between dalphins and whales.

Technically several species most of us consider whales are dolphins.

I realise there are a handful of fairly large dolphin species that are colloquially called whales, but these are still so morphologically distinct from comparably sized true whales that cross breeding would be extremely unlikely.
