Fossils cast doubt on human lineage originating in Africa

Fossils from Greece and Bulgaria of an ape-like creature that lived 7.2 million years ago may fundamentally alter the understanding of human origins, casting doubt on the view that the evolutionary lineage that led to people arose in Africa.

Scientists said on Monday the creature, known as Graecopithecus freybergi and known only from a lower jawbone and an isolated tooth, may be the oldest-known member of the human lineage that began after an evolutionary split from the line that led to chimpanzees, our closest cousins.

The jawbone, which included teeth, was unearthed in 1944 in Athens. The premolar was found in south-central Bulgaria in 2009. The researchers examined them using sophisticated new techniques including CT scans and established their age by dating the sedimentary rock in which they were found.

They found dental root development that possessed...
