Eve's footprint

Replica of 'Eve's footprints' (Geelbek visitors centre, West Coast National Park, Western Cape, South Africa).

Eve's footprint is the popular name for a set of fossilized footprints discovered on the shore of Langebaan Lagoon, South Africa in 1995. They are thought to be those of a female human and have been dated to approximately 117,000 years ago. This makes them the oldest known footprints of an anatomically-modern human. The footprints found at Nahoon in the Eastern Cape are older however, at 200 000 years. The estimated age of Eve's footprint means that the individual who left the tracks in the soil, thought to be female, would have lived within the current wide range of estimates for the date of Mitochondrial Eve.[1][2][3][4][5][6][7]

The above conclusions appear to be challenged by K.L. Kuykendall of the Department of Anatomical Sciences, University of the Witwatersrand Medical School, in an article entitled "Never letting the facts get in the way of a good story".[8]

History

The three footprints were found in 1995 by geologist David Roberts from the Council for Geoscience and announced at a press conference with paleoanthropologist Lee R. Berger of the University of the Witwatersrand at Johannesburg, South Africa, at the National Geographic Society in Washington, D.C., USA. The discovery was documented in the August, 1997, issue of the South African Journal of Science.[1]

Berger and Roberts say the prints were made on a steep sand dune during a turbulent rainstorm. The location where they were found is in southwest South Africa about 60 to 70 miles (about 100 kilometres) northwest of Cape Town in the West Coast National Park. They were found in a ledge of sandstone at the edge of Langebaan Lagoon near the Atlantic coast. The preserved prints were moved to the South African Museum in Cape Town for protection and a concrete replica was mounted on the shores of Langebaan.[2]

The maker of the footprints lived in the time of the emergence of modern Homo sapiens, or people anatomically similar to humans alive today.[4] The footprints measure eight and a half inches (22-26 centimetres) in length and are about the size of a modern-day (U.S.) woman's size 7½ shoe (British size 6, continental European size 39½[9]). In one foot impression the big toe, ball, arch, and heel clearly are discernible.[5] Roberts thinks that the prints belong to an ancient female about 1.5 meters (5'3" to 5'4") tall. He said that the woman who made these footprints would resemble a contemporary woman.[7]

Fewer than three dozen hominid fossils from the period 100,000 to 200,000 years ago have been found. Berger said, "These footprints are traces of the earliest modern people." Roberts explained further that dry sand blew over the wet footprints and filled the prints. They eventually were buried to a depth of about 9 metres (30 ft). The sand and accompanying crushed seashells hardened like cement into sedimentary rock and protected the footprints.[3]

The team later found associated evidence of stone tool use (a core, scrapers, cutting blades, and a spear point) in the same area that is believed to date from the same period. There also was evidence of the use of ochre, leading to the intriguing possibility that the 'Eve' of 117,000 years ago may have been wearing the colorful powder.[6]
