Expanding subsistence strategies beyond big-game hunting and the consequential diversity in tool types has been noted as signs of behavioral modernity. A number of South African sites have shown an early reliance on aquatic resources from fish to shellfish.
Pinnacle Point , in particular, shows exploitation of marine resources as early as , years ago, perhaps in response to more arid conditions inland. Blombos Cave and Site in Sudan both show evidence of fishing as well. Taphonomic change in fish skeletons from Blombos Cave have been interpreted as capture of live fish, clearly an intentional human behavior. Evidence was found in , dating to about , years ago at the site of Olorgesailie in Kenya, of the early emergence of modern behaviors including: the trade and long-distance transportation of resources such as obsidian , the use of pigments, and the possible making of projectile points.
The authors of three studies on the site observe that the evidence of these behaviors is approximately contemporary to the earliest known Homo sapiens fossil remains from Africa such as at Jebel Irhoud and Florisbad , and they suggest that complex and modern behaviors began in Africa around the time of the emergence of Homo sapiens.
In , further evidence of Middle Stone Age complex projectile weapons in Africa was found at Aduma, Ethiopia dated 80,, years ago, in the form of points considered likely to belong to darts delivered by spear throwers.

See Bryant , p. Unfortunately this consensus in principle hardly clarifies matters much in practice. For there is no agreement on what the 'qualities of a man' actually are," [ The only widely recognized archaic subspecies [ citation needed ] is H. The name H. However, Linnaeus postulated four other extant subspecies, viz.
This classification remained in common usage until the mid 20th century, sometimes alongside H. See, for example, Bailey, ;  Hall, This height is indeed cm lower than the height of post-WWII Europeans, but compared to Europeans some 20, or years ago, it is practically identical or even slightly higher. Such change in shape contributed to the increased cranial volume. Bioclimatic effects directly upon body size and indirectly upon brain size in combination with cranial globularity appear to be a fairly powerful explanation of ethnic group differences.
