    9. Phylogenetic Tree

    11. About 12 million years ago there is a fork in the tree where scientists and anthropologists believe human-like animals(hominids) separated from the apes.

    12. For awhile many scientists believed that this common ancestor was a human-like creature called Ramapithecus. Unfortunately because the only fossils of this organism that can be found are jaw bones and teeth, it can not be determined whether it is actually a human ancestor.

    13. An early ancestor of humans is a human-like creature called Australopithecus afarenis. This was one of the first complete skeleton fossil that was found.

    14. The next main character in the path of evolution is Homo habilis. This name means handy man or tool user. This is the first group of fossils that were found to be clearly human.

    15. Next on the phylogenetic tree is Homo erectus. They existed about 1.5 million years and their brain size is about 800cm3.

    16. The Neanderthals This is the earliest group of fossils to be classified as Homo Sapiens. These people appeared about 80,00years ago and became extinct about 40,000 years ago.

    17. The Neanderthals were thought to be fairly intelligent, fully bipedal and had strong muscles in the chest and arms. They had the ability to use fire and tools.

    18. Cro-Magnon Man It seems that Cro-Magnon man and Neanderthal man coexisted for a period of time. These people are modern in appearance.

    19. Cro-Magnon Man Cro-Magnon man was far more advanced than Neanderthals. They had the ability to make excellent tools, domesticate animals and plant food.
