Question

Quizplus · Accepted Answer

The Laetoli footprints provide the earliest direct evidence of bipedalism in hominins, as they show a hominin species, likely A.afarensis, walking upright on two legs. The footprints also suggest that A.afarensis had a stride similar to modern humans, indicating that they were efficient walkers and likely had the ability to cover long distances on foot. However, the footprints do not provide evidence for the size of the species or their social behavior, and there is no indication that they were either a prey species or had any particular predators.
