Walking With Cavemen - Episode 1 of 4 - First Ancestors
"It's 3.5 million years ago and in East Africa a remarkable species of ape roams the land. Australopithecus afarensis has taken the first ... all » tentative steps towards humanity by standing and walking on two legs.
"Just a few million years previously, Africa was covered, almost edge-to-edge, with dense rain forest. Our ancestors almost certainly used all four limbs to move and live and hunt in their tree-top homes. But massive geological turmoil changed their destiny.
"The rift valley was forming, and the rain forests dying as Africa dried out - turning the landscape into a mosaic of scattered trees and grass. In this new environment afarensis found it more efficient to move about on two legs rather than four."

Attention! Ne consultez surtout PAS les archives des mois précédents! En effet, je publie tant d'articles par jour que le contenu d'un mois est énorme, et de consulter un mois passé risque de faire crasher votre ordinateur. Utilisez plutôt la fonction "rechercher" et "sur le blog" tout en haut de la page ou la fonction "Search this blog" de Technorati dans la colonne de droite; ou mieux encore, utilisez la fonction "CATEGORIES" qui se trouve dans la colonne de droite. Je suis en train de travailler sur une éventuelle solution pour les archives mensuelles.
Caution! Do NOT consult the archives of past months! Indeed, I post so much every day that the content of any given month is enormous, and to consult any previous month could cause your browser or even your computer to crash. Better use the "search this blog" function - either at the top of the page or the Technorati one in the right-hand column. Better still, you could also consult the "CATEGORIES" in the right-hand column. I am currently working on a possible solution for the monthly archives.
