The new finding in paleoanthropology

Hy! I find this articule about phisical anthropoloy, one of the most important findings of this times:

An international team of scientist found a new fossil skeleton in Africa, named Ardi, short for Ardipithecus ramidus. This fossil take place in the gallery of human origins, whit an age of 4,4 millions years. It much more primitive than the famous Lucy (Australopithecus afarensis).

This finding is important because, like the scientist said, Ardi open a new window for undestanding the first steps of human evolution. This species can give us more information about the moment that took our ancestors after diverged from our comun ancestor whit chimpanzees.

Ardi probably stood four feet, and weighed about 120 pounds. Is a foot taller tha Lucy, and twice the weith.

The brain was the same large than a chimp. It had agility to climbe a tree, but probably walked on two legs. Walking on two legs is a very important innovation in hominids, it seems that Ardy is the very first hominid who has the hability to do it, but not very efficiently.

Ardi is the result of 17 years of study nad hard work. The paleoanthropologist wrote in one of the many articles, that Ardi is full of anatomical surprises. The most significant surpise is thta Ardi give evidence fot suport the hypothesis that walking in two feets had evolved as an adapatation to life on grassy savanna!
