The acquisition of bipedalism is considered to be a decisive step in human evolution. Nevertheless, there is no consensus on its modalities and age, notably due to the lack of fossil remains. A ...

You will be hard-pressed to find an animal that has no rudimentary or useless traits: Atrophied eyes, discarded wings, or male breasts, to name just a few of many. In males, for example, what is the ...

In fact, over 85% of the occurrences of bipedalism that were observed took place when the apes were in the trees. "Our study suggests that the retreat of forests in the late Miocene-Pliocene era ...

Walking on two legs has long been considered a milestone in human evolution and one of our most defining characteristics. Until now, researchers assumed that the first humans originated in Africa and ...

A 6-million-year-old fossil ape has shed new light on the evolution of human movement. For a study published in the journal Innovation, a team of scientists employed a novel method to study the skulls ...

The inner ear may not seem like a particularly bony place, but human ears in fact have three small bones (also known as ossicles): the malleus, the incus and the stapes. While most people would assume ...

One of the biggest questions in human evolution asks why humans became habitually bipedal about 7 million years ago. Most of our primate cousins do well walking quadrupedally and switch to two legs ...

It’s a much bigger question than it seems. Most animals, including most mammals, are quadrupeds (or greater — many arthropods and insects have six or more legs). We, and a few other primates, are ...

A new study has shown that humans may have evolved a spring-like arch to help us walk on two feet. Researchers studying the evolution of bipedal walking have long assumed that the raised arch of the ...
