Capuchin flakes are smaller and contain fewer fractured areas than ancient hominid
tools, says archaeologist David Braun of George Washington University in Washington, D.
This conclusion is further corroborated by electron microscope analysis of the tooth's masticatory surface, which reveals that the Bulgarian hominid
had consumed hard and abrasive objects like grass, seeds, and nuts.
The new species of hominid
was scientifically named Sahelanthropus tchadensis and was nicknamed Toumai, which means ''hope of life'' in the local language, according to the magazine.
He said its significance rivalled that of Australopithecus africanus, the first hominid
discovered 77 years ago, which confirmed the African origin of humans.
Typically, early hominids
would have made a stone cutting tool from a solidified lava cobble, found probably in a stream bed.
Scientists have found evidence of upright walking, or bipedality, in hominid
fossils as much as 4 million years old, which is about 1 million to 3 million years after the hominid
line split from the ancestors of the chimpanzees and gorillas.
Any organism that is more human than ape is called a hominid
(from a Latin word for "man").
A total of 12 early hominid
fossil specimens were discovered, including parts of one individual's skeleton.
That species is probably not Neandertal or Denisovan, but a different, related hominid
group, said Bohlender, a statistical geneticist at the University of Texas MD Anderson Cancer Center in Houston.
Gen Suwa, an anthropologist from the University of Tokyo Museum, have overturned the common assumption that manual dexterity evolved after the development of bipedal locomotion freed hominid
hands to use fingers for tool manipulation.
His discovery is being ranked with that of the first hominid
These discoveries are more complete and considerably older compared to the previously oldest acclaimed hominids
from Aramis, Ethiopia, aged 4.
