A workforce of scientists just lately found the age of over 50 footprints that have been present in fossilized seashore sediment close to Trachilos, Crete in 2017. They’re the oldest identified pre-human footprints ever discovered, relationship again greater than six million years.
The worldwide workforce of researchers revealed their findings in Scientific Experiences on October 11. Using geophysical and micropaleontological strategies to seek out the age of the footprints and estimated them to be about 6.05 million years previous.
The scientists imagine the footprints date from the Cenozoic period, making them the oldest footprints ever discovered of a human-like foot. In response to scientists, the fossilized footprints shed a lightweight on the early evolution of people strolling in addition to the dispersal of mammals from Eurasia to Africa.
“The tracks are virtually 2.5 million years older than the tracks from Laetoli in Tanzania, that are ascribed to Australopithecus afarensis (Lucy),” Uwe Kirscher, one of many scientists who led the research, mentioned.
In response to the scientists, these footprints are the identical age because the orrorin tugenensis, an early species of people that have been found in 2000. Nonetheless, fossils from the species embody numerous bones however no footprints or foot bones.

“The oldest human strolling foot had the ball of the ball, with a close-fitting and sturdy large toe, in addition to constantly shortening facet toes,” Per Ahlberg, a co-author of the research, mentioned. “The only of his foot was shorter than that of Australopithecus. An arch of the foot was not but pronounced and the heel was narrower. “
Right now, the island of Crete is the most important island in Greece and stretches roughly 160 miles. However throughout the time the footprints have been made, scientists imagine Crete was nonetheless related to the Greek mainland. On account of this, the scientists weren’t capable of rule out the likelihood that the footprints got here from the pre-human Graecopithecus freybergi.
This hominin was researched by one of many coauthors of the research, Madelaine Böhme, and her workforce in 2017. Her workforce recognized fossils present in Athens, Greece that have been over 7.2 million years previous. Böhme mentioned the footprints may have been created by these pre-humans.
In response to Böhme, the Orrorin tugenensis was the oldest prehistoric man, originating in Kenya between 6.1 and 5.8 million years in the past. Böhme believes the geographical distribution of early people over 6.25 million years in the past may have led to a big migration from Mesopotamia to Europe.
She additionally mentioned that the blockage of explicit continents from the desertification section of the Sahara 6 million years in the past probably led to a separate growth of pre-humans resulting in African and European prehistoric males.
The idea Böhme has coined “desert swing,” may clarify how short-term desertification within the Sahara and surrounding areas “managed” the migration of species from Eurasia to Africa.
