They roamed many habitats but used only one tool kit, amid unpredictable environments.

This is a clear sign that 2 million years ago humans were not constrained technologically and already had the capacity to expand geographic range, as they were ready to exploit a multitude of habitats within Africa—and, possibly, beyond.
