Open pies in Kenya the older human tracks until the moment
To borders of the Turkana lake, in the barren north of Kenya, an international team of investigators is shortage the oldest tracks known a hominino, of it does a million and average of years already it walked with feet of structure and operation similar to those of the Homo sapiens.
The finding that publishes Science has produced in the region of Koobi Fora, an authentic thematic park of fossil rest that has not stopped rendering pieces of puzzle human since it began to excavate itself does four decades under the auspices of Richard Leakey, prominent member of a famous clan of paleoantropólogos anglian-Kenyans. Her mother, Mary, would later discover 10 years the oldest tracks of a hominino in Laetoli (Tanzania), a group of footsteps whose age is considered in 3,75 million years.
In order to determine what homíninos their tracks in the mud of Koobi Fora imprimieron, “they were compared with those of Laetoli and with footsteps of the local population”, Bennett explains. The investigators discovered that the feet were “anatomically modern”, with a sharp bridge and a big toe next to the others and aligned with the axis of the foot, unlike the one of the simios, more separated and in angle to climb to the trees. The landlord of the step is similar to the one of the present humans and different from the one of the simios. All this difference to these tracks of those of Laetoli, attributed to a biped - the bipedalismo goes back to six million years but more simiescas, perhaps of a primitive Australopithecus.
“We knew then that the tracks had to belong to one of the three species that coexisted then in the zone: Paranthropus boisei, Homo habilis [both more primitive] or H. erectus (or its early form, H. to ergaster)”, says Bennett. The geologist concludes: “What they say us to the tracks on his corporal mass and height aims at erectus”, a hominino of great stature - their tracks equal in size to those of a present adult human who was, according to he is created, the first human ancestor who left the African cradle in search of other territories.
