Two fossils of an ape-like creature have been discovered in
Bulgaria and Greece, with specimens dating back 7.2 million years. An
international team of researchers discovered the 'Missing Link' in the
Mediterranean region, with the last common ancestor of both chimpanzees and
humans named Graecopithecus freybergi or ‘El Graeco' by scientists. This puts
our ancestors in Europe 200,000 years before they were in Africa, challenging
common perspectives on the origins of human history.
Even though Europe was an ape's paradise roughly 12 million
years ago, researchers used to believe they were confined to Africa after
environmental conditions deteriorated about 10 million years ago. That was
until the 2012 discovery of an ape tooth from Bulgaria that was just 7 million
years old, which shed new light onto the uncovering of a fossil jawbone found
near Athens in 1944. Following a complementary analysis that investigated the
local geology in Greece and Bulgaria at the time, scientists now believe that
Graecopithecus split from the chimp evolutionary lineage a little earlier than
7.25 million years ago.
The research team analysed the two known specimens of
Graecopithecus and used computer tomography to visualise the internal
structures of the fossils. Researchers then discovered that the roots of the
premolars were widely fused and shared additional dental root structures,
features that are characteristic of modern humans, early humans, and several
pre-humans. According to Professor David Begun, a University of Toronto
paleoanthropologist and co-author of the study, "This dating allows us to
move the human-chimpanzee split into the Mediterranean area."
According to Professor Nikolai Spassov, co-author from the
Bulgarian Academy of Sciences, “This study changes the ideas related to the
knowledge about the time and the place of the first steps of the humankind ...
Graecopithecus is not an ape. He is a member of the tribe of hominins and the
direct ancestor of homo ... The food of the Graecopithecus was related to the
rather dry and hard savannah vegetation, unlike that of the recent great apes
which are living in forests. Therefore, like humans, he has wide molars and
thick enamel. To some extent this is a newly discovered missing link. But
missing links will always exist, because evolution is infinite chain of
subsequent forms. Probably El Graeco's face will resemble a great ape, with
shorter canines."
Not everyone agrees with the implications of this finding,
however, with David Alba from the Catalan Institute of Palaeontology in
Barcelona not convinced by the idea that tooth roots alone can identify
Graecopithecus as a hominin. While Alba and others agree that Graecopithecus is
different from other ancient apes found in Europe, primates are particularly
prone to evolving similar features independently. While Professor Begun and
others involved in this study would surely disagree, some scientists are not
ready to accept such big evolutionary claims.
