An extinct hominid
could explain the history of humankind
Sharp-edged debris from such rock pounding raises questions about how hominid
Since finding Lucy, other fossils of the hominids
were discovered but they were either older than 3 million years or younger than 2.3 million years.
Researchers from the University of Tubingen in Germany said the ape's diet was similar to that of African hominids
, which only disappeared four million years ago.
Richard Wrangham and Dean Falk, both accomplished anthropologists, have each written a book presenting a novel theory on how and why the human lineage (a group of primates known as hominids
) developed characteristics that distinguish us from other animals.
Remains of a second hominid
of the same size and stature has been dated to 74,000 years ago.
"Most scientists agree that Toumai is a hominid
," says Pilbeam.
The fossil material -- a nearly complete cranium, two lower jaw fragments and three isolated teeth -- was recovered between last July and February, and constitutes a new genus and species of hominid
, the articles said.
He said: 'The new hominid
displays a unique combination of primitive and derived characters, suggesting a close relationship to the last common ancestor between humans and chimpanzees, suggesting him as a likely ancestor of all later hominids
And when finds are made, they have to be fitted into a vast time scale; depending on how we define the term "human", we are looking at a period of initial hominid
development of between six and three million years ago.
Any organism that is more human than ape is called a hominid
(from a Latin word for "man").
People from Melanesia, a South Pacific region encompassing Papua New Guinea and surrounding islands, may carry genetic evidence of a previously unknown extinct hominid
, Ryan Bohlender reported October 20.
