so who ever wrote that about 'hominin or not' - got mixed up?
because it is hominin.

The traditional definition of "hominin" is any fossil creature that arose after the human and chimp lines split. I looked up the paper cited as a reference for the aforementioned debate. This is what it says:

Quote:Is Ardipithecus a hominin?—that question
will likely dominate the paleoanthropological
debate over this fossil taxon for years to come.
In the 1970s, the discoverers of Australopithecus
afarensis described that fossil hominin as an
obligate terrestrial biped ( Johanson & White
1979). Further research offered the alternative
interpretation that AL-288 and her kin
were not fully terrestrial bipeds in the modern
sense and may have retained some adaptations
to arboreality (Stern & Susman 1983, Susman
et al. 1984), an analysis that may represent the
consensus view today. Further research and independent
study of the Ardipithecus fossils will
likely offer new interpretations of its behavioral
biology.

The argument seems to be that some people don't think it's a hominin simply because it wasn't fully bipedal.

RE: Ardipithecus - ape men?
because it walked on all fours ? how does that prove that is not hominin?

Because walking on two legs is considered a hallmark of humanity.

RE: Ardipithecus - ape men?
but according to the Ardi picture, it doesn't seem it would walk on all fours. Too big for that, maybe like Gorilla it does. Because Gorilla can bipedal IIRC? Mostly just the alpha males.

but didnt humans walk on all fours i thoguht once in history

or my alien theory connected with our gods is true

No, your alien/gods theory is not likely true. No evidence.

Skepticism is not a position; it is an approach to claims.

Ardi was drawn standing up because its a diagram to show off what she most likely looked like. She was actually quite small, about the size of a chimpanzee. Gorillas can only go bipedal for short periods of time. They are primarily fist walkers. All species that fall under the genus Homo were all completely bipedal.

I've talked to you about the alien stuff on the other forum. It's best that any further comment on the subject be moved to the "Skepticism, Pseudoscience, and Conspiracy Theories" subforum.

RE: Ardipithecus - ape men?
I thought Gorilla was Gorilla gorilla - Gorillas can bipedal as you can see in some YouTube videos. fist walkers? What's that.

but Ardi - is it still a human ancestor even tho they may of not been a hominin?

Gorillas have their own genus. This is separate from the genus Homo. They can move bipedally, but they primarily walk on their fists/knuckles, hence the term fist walking.





She certainly is a human cousin. I don't think there is a consensus yet as to whether or not she is ancestral.
