New Ethiopian Fossil Teeth Reveal Early Human Ancestor
Scientists found old teeth in Ethiopia from a new member of the human family tree.
These teeth are from a time when humans had not yet evolved, but ancestors of the Homo genus existed.
The new species lived with early Homo species in the same region.
This means multiple kinds of human ancestors lived together.
The scientists are trying to see if these ancestors ate the same foods or competed for resources.
This discovery helps show that human evolution was not a straight line.
Researchers discovered new Australopithecus teeth fossils dating back approximately 2.65 million years.
The fossils were found in the Afar Region of northeastern Ethiopia.
The teeth belonged to a new Australopithecus species and early Homo species.
The findings suggest four hominins coexisted in East Africa.
Scientists are investigating resource competition between the species.
