Use the 9
steps of evolution by natural selection to explain how the
body type of Homo erectus & heidelbergensis
(both had very similar bodies) could then change to a
Homo neanderthalensis body.
Begin with a specific
morphological change in the body of a Homo
heidelbergensis, combined with the relevant selection
pressures and adaptive benefits, to work your way through each of
the nine steps to explain the evolution of Neandertals.
