[35] [37] Human lice can also shed light on human migratory patterns in prehistory. The dominating theory of anthropologists regarding human migration is the Out of Africa Hypothesis. Genetic diversity accumulates over time, and mutations occur at a relatively constant rate. Because there is more genetic diversity in African lice, the lice and ...
Genetic analysis of clothes or body lice, which are one of three lice to live on humans, revealed that humans likely began wearing some form of clothing at least 83,000 years ago, according to a ...
The head louse (Pediculus humanus capitis) is an obligate ectoparasite of humans. [1] Head lice are wingless insects that spend their entire lives on the human scalp and feed exclusively on human blood.

Nakedness and clothing use are characteristics of humans related by evolutionary and social prehistory. The major loss of body hair distinguishes humans from other primates. . Current evidence indicates that anatomically modern humans were naked in prehistory for at least 90,000 years before they invented clothi
