Homo sapien sapiens or Homo sapiens sapiens?

Answer 1

It depends on whether you think Neandertals and modern humans were members of the same species, in which case it would be: Homo sapiens sapiens and Homo sapiens neanderthalensis (i.e., they were simply different SUB species) OR whether you think they were two separate species: Homo sapiens and Homo neanderthalensis.

Homo = our genus name

'sapiens' = is our species name. Note that you ALWAYS write the genus name with the species name because two species might have the same species name. For example, Pan paniscus and Ateles paniscus.

Answer 2

Homo sapiens is the scientific name for modern human beings.

At some point between 400,000 years ago and the second interglacial period in the Middle Pleistocene (around 250,000 years ago) the trend in cranial expansion and the elaboration of stone tool technologies developed, providing evidence for a transition from homo-erectus (meaning "upright man") to Homo sapiens (meaning "wise man"); this origin/transition is speculated by human scientists as either due to a uni-regional development that spread (which seems likely, due to the general genetic homogeneity of Homo sapiens sapiens) or multi-regional developments that merged.
