The discovery of these footprints settled the issue, proving that the Laetoli hominins were fully bipedal long before the evolution of the modern human brain, and were bipedal close to a million years before the earliest known stone tools were made. [11] The footprints were classified as possibly belonging to Australopithecus afarensis.
The footprints measured between 140 and 260 mm (5.5 and 10.2 in), thought to equate to heights between 0.9 and 1.7 m (2 ft 11 in and 5 ft 7 in). It is believed that the individuals who made them were from the species Homo antecessor , [ 7 ] known to have lived in the Atapuerca Mountains of Spain around 800,000 years ago.
Fossilized footprints of Homo erectus were found in Ileret, Kenya.Science reported that there were multiple trails of footprints found at the Ileret site: “two trails of two prints each, one of seven prints and a number of isolated prints.” [4] These footprints reveal that these early hominins most likely traveled in groups—evidence which researchers see as a sign of social behavior. [5]
The footprints have generally been classified as australopith, as they are the only form of prehuman hominins known to have existed in that region at that time. [ 38 ] According to the Chimpanzee Genome Project , the human–chimpanzee last common ancestor existed about five to six million years ago, assuming a constant rate of mutation.
Human footprints in White Sands National Park in New Mexico. Stone, bone, and wood artifacts and animal and plant remains dating to 16,000 BP in Meadowcroft Rockshelter, Washington County, Pennsylvania. (Earlier claims have been made, but not corroborated, for 50,000 BP at sites such as Topper, South Carolina.) [61] [62] [63] Europe: Sicily: 20
According to the study, the Trachilos footprints may represent an early hominin or primate species that may have evolved hominin-like feet independently, outside of Africa. [1] It also suggests the possibility of convergent evolution, wherein unrelated species adapt similar traits and characteristics to each other.
