There are many theories about early humans - where they came from - how they evolved - and how they are evolving in the next step of humanity's journey. One theory describes intervention by ancient aliens as part of one or more biogenetic experiments whose exact propose has not as yet been defined. Each year discoveries are made which lead to more questions as humanity seeks its source of and purpose for its creation.
Many human 'prototypes' coexisted in Africa BBC - August 9, 2012
Fossils from Northern Kenya show that a new species of human lived two million years ago, researchers say. The discoveries suggests that at least three distinct species of humans co-existed in Africa. The research adds to a growing body of evidence that runs counter to the popular perception that there was a linear evolution from early primates to modern humans.
New Flat-Faced Human Species Possibly Discovered Live Science - August 8, 2012
New fossils from the dawn of the human lineage suggest our ancestors may have lived alongside a diversity of extinct human species, researchers say. Although modern humans, Homo sapiens, are the only human species alive today, the world has seen a number of human species come and go. Other members perhaps include the recently discovered "hobbit" Homo floresiensis. The human lineage, Homo, evolved in Africa about 2.5 million years ago, coinciding with the first evidence of stone tools. For the first half of the last century, conventional wisdom was that the most primitive member of our lineage was Homo erectus, the direct ancestor of our species. However, just over 50 years ago, scientists discovered an even more primitive species of Homo at Olduvai Gorge in Tanzania they dubbed Homo habilis, which had a smaller brain and a more apelike skeleton.
New Kenyan fossils shed light on early human evolution PhysOrg - August 8, 2012
Exciting new fossils discovered east of Lake Turkana confirm that there were two additional species of our genus - Homo - living alongside our direct human ancestral species, Homo erectus, almost two million years ago. The finds, announced in the prestigious scientific journal Nature on August 9, include a face, a remarkably complete lower jaw, and part of a second lower jaw.
