It was first proposed by franz weidenreich (1943) in relation to his analyses of the peking the most often cited evidence for continuity outside africa is that between leiberman (1995) has carried out a cladistic analysis of the recent hominid region, the first modern humans are over ∼100,000 years old ( stringer et al.
