This finally equipped our ape ancestors with symbolic abilities, which in turn greatly enhanced communicative efficiency. The sequence of the human society evolution seems to be the improvement of efficiency in social communication, the manufacture of single blade stone axe, the development of "hands"...

The human hand can be distinguished from that of apes by its long thumb relative to fingers1–4 (Fig. 1a), which has been related functionally to different selective regimes—manipulation vs locomotion—acting on human and ape hands1,5. During the first half of the twentieth century, ...
Prolonged female postreproductive life—hereafter menopause—is an evolutionary oddity that has puzzled biologists and anthropologists for decades. In human societies, women living under natural survival and fertility can expect to spend an average of 42.5% of their adult life postreproductive1. This co...
