ultimately gave rise to the genus Homo‚ which includes Homo sapiens. But not everyone agrees with this view. Critics say the skeletons are not old enough to be the precursors to Homo. Others say the similarities can be chalked up to the diversity of early hominids‚ but that aspects of A. sediba’s anatomy make it unlikely candidate for being our forebears.

million years old‚ which predates the earliest known "Homo" species. There is no known evidence that any "Homo" specimens appeared by 2.5 million years ago. A Homo fossil was found near some Oldowan tools‚ and its age was noted at 2.3 million years old‚ suggesting that maybe the Homo species did indeed create and use these tools. It is surely possible‚ but not solid evidence. Bernard Wood noted that "Paranthropus" coexisted with the early Homo species in the area of the "Oldowan Industrial Complex"

regions and mixed together which contributed to the development of the modern human. What makes these theories the most highly debateable in paleoanthropology is that 30‚000 years ago‚ the taxonomic diversity previously seen amongst homo sapiens‚ homo erectus and homo Neanderthals had vanished and humans everywhere had evolved into the anatomically and behaviourally modern form; there is much deliberation as to how this occurred which rose this differing schools of thought; one that emphasises multiregional

Working to succeed and survive requires certain behavior and execution. It was not as easy to live at the time of the Homo erectus‚ Neanderthals‚ and Indians form the twentieth century. They had many problems‚ which made it difficult to survive. Some of their problems are problems that we still have today‚ but with our improvements such as new studies and technology‚ it is much easier for us to deal with these situations. They needed order and systems. They needed a leader; one who could take the

a group of scientists found the partial skeleton of a new human species we had never seen before. Researchers called the remains LB1‚ also nicknamed the hobbit due to its small size. It was first believed that this new species‚ Homo floresiensis‚ was a descendent of Homo erectus that had simply dwarfed over time due to limited access to resources. However‚ newer studies have highlighted some of the more primitive characteristics of LB1‚ which lead scientists to believe that the hobbits branched off

Surviving in Africa Film Summary Three million years ago in Africa‚ early hominids walked around upright. What we know about them is minimal and teams of archaeologists spend their lives searching for clues that might help us to better understand their ways of life. Don Johanson‚ a well-known archaeologist‚ and his team spent many years in Africa in the early 70s searching for remains left behind by our early ancestors. In 1974 Don discovered a bipedal skeleton that was about one third
