#2 Geez, attend an extended family reunion and you will reach this opinion on your own.

#3 That interbreeding thingy is still going on out in the African bush (although not with offspring anymore). Isn't that how the monkey HIV virus first transferred to humans? There are always those for whom any mammalian orifice will do in a pinch. *shudder*

#4 Moreover, the speciation process was unusual – possibly involving an initial split followed by later hybridization before a final separation.

Sounds like very early examples of multi-culturalism.

#6 Additional findings reveal a particularly young age of one of the human sex chromosomes and point to a complex process of speciation, with possible interbreeding during speciation.

To quote Frank Zappa (re: AIDS coming from monkeys): "So, who's been plunkin' the monkeys?"

#8 About HIV, some guy named Hooper came out with a very boring, unnecessarily long book about how SIV-->HIV might have been the unintended result of early polio vaccine trials, but he couldn't prove it.

Humans probably had some sort of hybridization event after breaking off from the rest of the family tree. Humans are the only apes with 23 pairs of chromosomes instead of 24. I've seen some proponents of aquatic ape theory suggest that this hybrization occured between a group of saltwater swimmers bred with a group of freshwater swimmers.

#9 Aquatic apes? Hooper? Wasn't he into sharks?

#11 Humans are the only apes with WEBBED FINGERS. So, we must be the Aquatic apes.

Actually, a good argument can be made that we made the intertidal zone our home. Its fits.
Omnivore: Meat, shell fish, fish vegies.
Webbed: Lion comes by you swim out to sea a bit.
Shark comes by you return to land further down the coast than the Lion.
On the way you pick some clams up and a little seaweed and have sushi.

#13 Having 23 chromozomes instead of 24 would be, IMHO, a serious impediment to hybridization by cross-mating. Nothing a serious geneticist can't bridge, but there were none presumed to occur at the time ~ 6mya, or even 100kya. Actually, the 2nd and 3rd ape-ish chromosomes look as if they were, for the lack of better word, 'spliced' in humans. What does that mean? Nobody has the faintest... We can conjecture til kingdom come, but that would be all we can come up with--conjectures.

Apropos, I would like to see the methodology for the revelation in the article, specifically The relative age of genetic changes between the human and chimp genomes varies over a period of ~ 4 million years. Without available genome of the represenative samples in between ~6mya and now, it is possible to generate gazillion of scenarios, depending on where in the genome you look.

Oh, yea, the aquatic ape theory... if true, the sea otters should have no hair either. But nooo, they don't want to get rid of it since at least Miocene.

#14 So where does the bonobo fit in all of this? I suspect (with zero supporting evidence I should point out) that this strain is implicated here.

#15 KBK - sorry, I was responding to two seperate ideas in my post. The Hooper book is here.

Some aquatic ape stuff is here.

#16 I find the aquatic ape hypothesis persuasive. It's not just the physical evidence, its also the behavioral evidence. Ever wonder why people pay a fortune for beachside property, or why kids are fascinated by ponds, streams and other bodies of water.

#17 I remember reading a popularization of the aquatic ape theory back in the '70s. Supposedly that's why young females grow long hair (for the floating babies to grab on to), and adult males go bald (I didn't quite grasp the explanation for that one, I'm afraid). I don't remember any explanation for why some men have hairy torsos, and others are practically bald, chestally. ;-)

#18 Different genes evolve at different rates, no surprise.

Fascination with water may have as much to do with spending the warmest, safest time of one's life in a sea, Mom's womb.

Also, there is another view you can take on this, which is protien evolution, not just gene.

#20 This is a complete crock. It goes against everything we know about human paleontology, anthropology, and our race's history. It's equivalent to revisionist archaeology by a group that has determined to determine that we are closer, genetically, to chimps than we actually appear, genetically, to be historically IMO.

There is hard evidence that "modern" humans go back a helluva' lot farther than most paleontologists, anthropologists, and archaeologists are willing to admit in public. In private, however, they will tell you that our species is far older than we think it is or may believe it might be.

There's even recent genetic evidence to intuit that dogs and humans are gentically closer, due to our long history together, than chimps and humans are.

We simply do not, currently, understand how species cross-polonization of genetic material occurs or why.

Until we do, genetic studies like the one cited here are highly suspect.

In addition, the stufy would seem to deny the archaeological and dated fossil record of a long line of human/hominid ancestry dating back more than a dozen millions of years. It would deny Austrolopithecus, Homo Erectus, Neanderthal (on off shott shown conclusively to have not given rise to Homo Sapiens), and possibly even Cro Magnon ancestry for modern humans IMO.

(Yes, I do know a little about the science - everything else I learned by working, occasionally, at the Joint Genome Institute)
