Here, we propose using a simple one, the Evolutionary Species Concept, on the grounds of considering that separation of populations &ndash; disregarding other issues &ndash; is enough to describe the evolution of the human lineage. The question of the acceptable number of Middle Pleistocene hominin species is used as an example. Camilo J. Cela-Conde, Marcos Nadal ##submission.copyrightStatement## Thu, 02 Feb 2012 15:51:59 +0000
