Scientists uncover new species of human ancestor

Name: Scientists uncover new species of human ancestor
Source: University of New South Wales
Date: April 9, 2010
Link:http://www.biologynews.net/archives/2010/04/09/scientists_uncover_new_species_of_human_ancestor.html

Summaries: In this article a team of 60 scientist have discovered a skeleton of an adult female and a child's skeleton. Dr. Andy Herries from the University of New South Wales was also apart of this discovery. These skeletons were found in South Africa. The skeletons are about 1.95 million to 1.78 million years old. Those two skeletons were from a new species. The name of the new species is called Australopithecus sediba. This species has similarities to the bipedal ape and an early homo. This article shows us that there are more species that were around that we don't know about that are extinct. It makes me wondered what other new species are out in the world.

    Question: How do they know the species is an ancestor of humans?

    Answer: The species has many traits that are similar to that of humans, such as being able to walk upright on two legs. Also, they were ancestors of many Primates, who happen to be closely related to humans. However, it's not certain that this species was an ancestor of either of these species; it's only known that the species was closely-related to both humans and our close relatives.

    P.S. - this is Erin Clingenpeel. I had to use a former name...

    IS Australopithecus sediba an actual Ancestor of humans?
    Actually some scientist are saying the fossils do not match that much. They look at the bones of the Female and it say that it may be ancestor of the ape but the bones doesn't directly match that of a human in most aspects. According to Dr. J.L Wile out of 7 claims the scientist made who discovered the "extinct Ape" Only 3 out of seven actually match. So it is still possible for it to be a direct descendant, but scientist still isn't sure. More research is still going to have to be made on the bones of the child before a conclusion can be made.
