Two Fossils
The geologists and a paleontologist went to find a jawbone of Homo habilis at 1.44 million-years-old in Kenya. This shows how two early humans lived together for half a million years in Africa. Next, they found a 1.55 million-year-old skull of Homo erectus in Kenya. Brown and Gathogo determine the order of volcanic ash layers above and below the fossils which allows scientists to determine the ages of the fossils. Journal Nature described the two fossils. Koobi Fora Research Project discovered the two fossils. Gorillas are in the article. Both are found in 2000 at Ileret region. This is significant because if Homo habilis and Homo erectus lived at the same time, then humans formed from both of them over the years. http://unews.utah.edu/old/p/080607-1.html

With all these new bones being found more is found on the past life. Little things like jaw bones are a huge deal in the field because were finding more out on the people. 1 million years is a long time and to see how life was then.Also this helps us know when certain species branched off and moved to where. Information like this shows movement in culture and people like tools and homes.The more bones we find the more we can learn.
