Australopithecus afarensis The most famous example of afarensis was the skeleton of 'Lucy' discovered in 1974 at Hadar in Ethiopia. Homo habilis Meaning 'handyman', Homo habilis was probably the first of our ancestors to use stone tools and thrived 2.2 - 1.6 million years ago. Homo erectus Homo heidelbergensis The heyday of this stout, thick-boned species was probably around 400,000 to 500,000 years ago. Homo sapien
Eskeletons Australopithecus - evolucion humana la historia de los primates más antigua, y hoy muy bien conocida: A. afarensis. Gracias a estas dos especies la caracterización de esta línea de homínidos primitiva es muy precisa. Se trata de especies de pequeño tamaño corporal, con una capacidad craneal ligeramente superior a la de los chimpancés, bípedos (los rasgos de adaptación al bipedismo de la tibia de A. anamensis hallada en Kanapoi retrasaría medio millón de años el desarrollo de una locomoción bípeda), pero que conservan algunos rasgos primitivos en sus extremidades, como las proporciones entre sus miembros o las falanges más o menos curvas. El primer homínido conocido, Ardipithecus ramidus, ocupa la base del árbol filogenético. Por su primitivismo, se considera el antepasado común a todos los demás homínidos. A continuación se sitúa A. anamensis como descendiente de A. ramidus y puede ser el antecesor de la siguiente especie, A. afarensis y/o de una especie aún no conocida que diera lugar a A. africanus y al primer Homo.

A Science Odyssey: You Try It: Human Evolution When did humans evolve? Who are our ancestors? Why did we evolve? At the turn of the century, scientists could only dream about finding the answers to these questions. The fossilized remains of a species known as Neanderthal had been found, and there was a primitive, human-like skull that had been discovered in Indonesia. Beyond that, there was little hard evidence to work with. With the 1912 "discovery" of the Piltdown Man, the study of human evolution was sent down a wrong track. There have been many discoveries, and much has been learned about the human odyssey over the past few decades. This activity shows the major hominid (human or human-like) species discovered to date, when they lived, and how they might be related to each other. More...
