Different species concepts, which broadened the scope of Mayr’s Biological Species Concept, have been put forward aiming to produce sound taxonomies of fossil taxa. Here, we propose using a simple one, the Evolutionary Species Concept, on the grounds of considering that separation of populations – disregarding other issues – 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.
