Bipedalism in humans may have come from foraging in treetops, research suggests
Guardian (UK) ^ | Wednesday, 14 Dec 2022 | Nicola Davis

The ancestors of humans may have begun moving on two legs to forage for food among the treetops in open habitat, researchers have suggested, contradicting the idea that the behaviour arose as an adaptation to spending more time on the ground.

The origins of bipedalism in hominins around 7m years ago has long been thought to be linked to a shift in environment, when dense forests began to give way to more open woodland and grassland habitats. In such conditions, it has been argued, our ancestors would have spent more time on the ground than in the trees, and been able to move more efficiently on two legs.

But now researchers studying chimpanzees in Tanzania say that trait may have different origins...

Writing in the journal Science Advances, the researchers report how they spent 15 months studying 13 chimpanzees living in Issa Valley in western Tanzania, an environment similar to that experienced by our ancient ancestors.

The results reveal that these chimpanzees spent a greater proportion of their time on the ground, and in movement, when in an open environment of woodland and grasses than in densely forested parts of the same area.

However, even in the open environment, the proportion of time the chimpanzees spent on the ground was similar to that previously recorded for other populations of the apes living in densely forested areas, including Gombe and Mahale...

The team says that while the study cannot prove that our human ancestors showed the same patterns of bipedal behaviour, it calls into question common assumptions of how humans ended up walking on two legs, and suggests that trees continued to play a role in our evolutionary story even as the environment shifted.<

“…it calls into question common assumptions of how humans ended up walking on two legs,…”

_____________

Atheists are always wrong about our origin, because of their refusal to admit the truth.

They listen in denial.

bipedalism

noun

The habit of standing and walking on two feet; the state of being bipedal

the bodily attribute of being bipedal; having two feet

So all animals with 2 feet use them to get around. Almost like God and Nature intended. I am losing more and more respect for the word "Science" as more and more of these scientific papers get published.

Does quadrapedalism originate from bi-bipedalism?

My mom had a cookie cutter of a man with two legs, so that’s why.

If evolution, to the point of speciation, was real, it would be more likely that humans found it advantageous to use their their hands to carry things or throw things than to forage in tree tops.

The positioning of that particular hole in our heads just doesn't get enough respect.

Researchers like to fabricate elaborate stories to keep the funding coming in, research suggests.

Sounds like settled science to me. After 7 million years surely we got it right?

7m years?

We sure frittered away 6.9m of ‘em before we did anything with it.

Try try try. Always trying to disprove the obvious and cloudy up reality. Sigh.

I don’t believe so. Anything that could maybe point to something they don’t understand and BAM! Evolution!

Binarypedalism is used to transport oneself, so wouldn’t that be...

trans-non-binarypedalism?

If they were bipedal they could have run...faster.

Carrying their wheat n stuff.

;)

That’s really a neat story.

Well, my ancestors developed feathers and wings to do that.

We age bugs before Soros said to.
