Old Bones

For the original article click here

Archeologists have discovered two million yer old bones (and possibly skin as well) from an apelike species that may have developed into the first humans. He is known as the Australopithecus Sediba. He was discovered in the Malapa Region in South Africa in 2008 and the first time it was mentioned was last April. From studying him scientists think that he was capable of using and making tools of the materials around him. They also think that they found some fossilized skin, and when and if they can prove it that will be the first time we find soft tissue from that long ago. Also it is very important because it comes from a very important time to us. The reason that time is important is because it makes us who we are today and we know little about it. There were two bones found, one from a teenage boy and one from a (about) thirty year old femal. The died either hours or days apart from each other. They also, possibly, could have been related. Both of them contain an unusual mix of primitive and derived—or human-like—traits. An example was that the female that her ankles allowed her to walk straight, but she had ape like heels. She was about four feet tall and the Sediba climbed tree, but were also able to walk straight. Also from studying them we see that their brain was similar to ours, but was the quarter of the size of our modern day brains and their brain was just a little larger than a chimpanzees.
