Homo erectus

First discovered in 1891, Homo erectus is one of the earliest-known and most geographically widespread species in the hominin fossil record. Fossil evidence attributed to this species has been found in Africa and Asia, as early as 2 million years ago and as late as 106,000 years ago. Whether these varied fossil samples really represent a single phylogenetic group is a matter of continuing uncertainty.

How capable were early human ancestors of crossing open water?

In past populations we should keep in mind the exceptional ability of humans to adapt to new circumstances.

A look at the intentional markings of Homo erectus

Looking at a 2014 paper by Josephine Joordens and coworkers, which describes zig-zag markings on a shell from Trinil, Indonesia. This shell may have been intentionally marked by Homo erectus.
