In this tutorial, students will identify the fossil evidence for the evolution of bipedalism then hypothesize about the evolutionary pressures affecting bipedal behavior.

John Noble Wilford, a "New York Times" science writer, outlines various hypotheses on the origin of bipedalism.

Article discusses the importance of Lucy to the theory of evolution and her bipedalism form of locomotion. Archived.

This lesson plan explores the primates in the African savannas that were the first animals to walk erect (bipedalism), which is a milestone in human evolution.

From ABC News in Science, Will Dunham's article on orangutans covers topics related to the evolutionary process of "bipedal walking," or walking on two legs instead of four.

In this exercise you will build two skeletons, one of an ape and one of a modern human being. The bones have been completely mixed up so its up to you to find the right fit. In this exercise you will learn about the unique...

Explore walking upright, tools and food, bodies, brains, social life, language and how humans ultimately changed the world. Excellent charts, pictures and videos accompany easy-to-understand text on the earliest humans.

Primates are a group of mammals that include apes, humans, monkeys, and prosimians. Primate characteristics and anatomy are explored, as well as life cycles, behavior and diet. Human impacts on other primate species have been...

Talk Origins gives a broad description of the types of Hominid species, and then gives a description of each species. Includes the specific characteristics of each, and explains the differences between the species.
