Dear MEL Topic Readers,

Being human: Big toe clung on longest to primate origins

Bipedal locomotion means standing or walking on two feet. Humans, birds and occasionally apes walk bipedally. Humans, birds, many lizards and cockroaches run bipedally. Kangaroos, some rodents, and many birds hop bipedally. This evolution in humans was aided by the development of an upright head and backbone and of an arched foot. It allowed humans to walk or run and use their hands freely all the time. In the meantime, humans lost their ability to grasp things like tree branches during the evolution. This shift took much longer time than previously thought. It seems that giving up the ability to live in trees and committing fully to bipedal life was not an easy or quick transition while it gave humans mobility and ability to live in different environments.

How was this evolution process found and studied?

Enjoy reading and learn about the mechanism of bipedal locomotion and human evolution.
