I don't think we were solely responcible for the extinction of the other hominids or apes... I'm saying we are a very efficent nail in the coffin....
one of the most tramatic things a species can experience is a change in its environment... this was happining as the glaciers advanced and then retreated creating new ecosystems and distroying old ones....
species that cant adapt to new conditions die off... we do have a habit of helping them allong though...eaven you cant argue that one
Plese explain your 'universal' myth of aliens interbreading with humans... I've heard no such myths from my people... Perhaps aliens created westerners?
races exist because people adapted to different environments with the help of localized gene pools... much like why different breeds of horses, dogs, cattle, sheep and goats exist.... the genetic difference is absolutely tiney... .001% of the DNA.
the primary difference... mellinin ammounts is how people adapted to differing ammounts of UV radiation... more UV exposure, more mellinin, darker skin... Less UV, less mellinin, lighter skin...
I dont ignore the skulls from anywhere... The skull binding phenomina was quite common all over the americas... Peruvian, Mayan, the "Flat-heads" of california, eaven my own Cherokee ancestors performed this body alteration.... you can tell from the formation of the bones that they were altered as they grew... much like the foot binding practice of China or the 'giraffe neck' practices of maylasia and africa... it shows on the bones.
every branch of science debates its basic belief systems...
I'll use paleontology as its my strongest field...
The most earth shaking arguments began in the 60's and continue today... such as the warm-cold debate in referance to metabolism in dinosaurs... we are also still debating the 'avian origens'....
both of these theories are mostly settled but science is about pushing theories and so the debate continues in a good natured way... keeping science on its toes...
other arguments include...
T.rex.. hunter vs. scavenger
Oviraptor egg theif or good mom...
how the heck did stegosaurus do it?
flight mecanics of pterosaurs
swimming mecanics of plesiosaurs... boy I bet they would love to see a living one to settle that debate!
I personally don't fully agree with the feathered baby T-rex... We know from skin impressions of fully grown Carnotaurus that they had boney noduals like a mosaic in thie skin (like the legs of a bird)... T-rex being a relitively close cousin to carnotaurus probably had skin like this as well...
However I am amazed by the number of good specimins of other theropods with feathers we are finding... such as the Dromeaosaurs (raptors in JP) Therizrinosaurs (wierd plant eating threopods) Oviraptors (the 'infamous' and falce egg thief)
dozens of new birds such as Confusicornis
Scinosauropteryx (a basal little celeosaur)
et cet...
as for this one :

from my reading of it... they arn't ignoring him they are simply waiting for more evidence... a valid thing in science... Archeology is well known for its arguments on dates and its considered the most importent thing for them to verify...
look at Monte Verde... they are going back to the site more than 20 years later in hopes of getting better dates because they are so hotly debated... to think that the 'establishment' isn't intrested in obviously important sites is falce....
ps.. I saw an intresting documentery a few years back about the 'maping-guari'(sp) supposidly a living giant sloth... a biologist heard about it from the natives and decided to devote his life to finding it....
they spent several weeks in the jungle, going to all the places he knew it would be... they never found it... but they got some hair and dung samples that later turned out to belong to tapirs and monkeys...
but who knows maybe some day...
also they had reports of 'giant prehistoric elephants' in far northern india... it was hoped that they were mammoths... they also got DNA samples from the supposedly prehistoric animals... they turned out to be regular asian elephants... just a little bit bigger than normal...
