Biology

The Neanderthal species is inferred to have been largely similar to Homo sapiens, but with some distinct features as listed below.

Size

Neanderthal adult height averaged about 160cm, and average body mass is estimated at about 60-85kg    

Growth

Most data suggest that the Neanderthals had an extended period of growth similar to, or only slightly accelerated compared with, Homo sapiens.

Life Expectancy

Skeletal data suggest that it was rare for a Neanderthal to reach 50 years in age.

Physiology

This is assumed to have been largely similar to that of Homo sapiens, but with the possibility of a somewhat higher metabolic rate.
