n 1978, a 75-centimeter trace of clear human footprints was discovered in a layer of volcanic ash aged 3.75 million years.

In addition, the growth of Australopithecus, and, accordingly, their bones, including the foot, was significantly smaller in size than modern humans.

So where does a 75 cm long track come from?
