University
of Melbourne – provides an unparalleled data set
for comparing these Late Pleistocene Homo sapiens
with earlier fossil trackways. With estimates that the
size of modern humans has reduced by around 30%
since the end of the Pleistocene, rare trace fossils of
human locomotion such as the Willandra trackway
represent a treasure trove of information for understanding
the evolution of human movement.
