What is significant about the Laetoli footprints?
Based on analysis of the footfall impressions “The Laetoli Footprints” provided convincing evidence for the theory of bipedalism in Pliocene hominins and received significant recognition by scientists and the public. Dated to 3.7 million years ago, they were the oldest known evidence of hominin bipedalism at that time.
What type of fossils are the Laetoli footprints?
The Laetoli footprints were most likely made by Australopithecus afarensis, an early human whose fossils were found in the same sediment layer.
How did natural events help to preserve the Laetoli footprints?
The Laetoli footprints were formed and preserved by a chance combination of events — a volcanic eruption, a rainstorm, and another ashfall.
How many individuals made the Laetoli footprints?
The fossils found at Laetoli date to a period between 3.76 and 3.46 million years ago (mya). They come from at least 23 individuals and take the form of teeth, jaws, and a fragmentary infant skeleton. In volcanic sediments dated to 3.56 mya are trails of remarkably humanlike footprints (presumably made by A.
What did Ardi look like?
Ardi weighed about 50 kg (110 lb), and could be up to 120 cm (3.9 ft) tall. Although she is a biped, Ardi had both opposable big toes and thumbs in order to climb trees. It is speculated that her bipedality impeded movement, but enabled her to bear more offspring.
