The human ancestors in the Tethys Sea. Dissemination 89th
There is a general tendency to think that the ancestors of the human species lived exclusively in the Rift Valley (South-Africa). However in recent years many discoveries are questioning this hypothesis, putting the spotlight to the tropical islands disappeared in Tethys Sea.
The Cubria sea 100 million years ago, a wide extension occupying the surface of the planet currently goes from the western Mediterranean to the Pacific Ocean. The movement of Laurentia (now Africa) and India towards Baltica (present Eurasian place) closed the sea (for 10 milion years) converting into the Mediterranean and caused desiccation 5 million years ago.
These movements brought out the sediment surface, not petrified, the seabed of the ancient Tethys and this has facilitated the discovery of fossils of small apes, whose characteristics correspond to anthropomorphic species, common ancestors of gibbons, great apes and humans.
Among these above mentioned discoveries we highlight 3 species: Pieralopithecus catalaunicus aged 13 million years, Pliobates Cataloniae aged 11.6 million years for the middle Miocene and anoiapithecus aged 9 million years. They all are discovered in sediments of the middle Miocene in Hostalets de Pierola (Barcelona). We can also point to the fossil of Hispanopithecus laietanus aged 9 million years discovered in Sabadell (Barcelona).
The anatomical characteristics: these Mediterranean apes as the last ancestors of common gibbons, big apes and humans; they are in the functionality of the elbow and wrist. Both have rotation capacity which you cannot find in most of the primitive primates but in subsequent apes
