This migration out of Africa is estimated to have begun about 70, 000 years BP and modern humans subsequently spread globally, replacing earlier hominins either through competition or hybridization.

It has been proposed that human genes " evolved with the expectation of requiring a certain threshold of physical activity " and that sedentary lifestyle results in abnormal gene expression .< ref name =" Cordain1998 "> Compared to ancestral humans, modern humans often have substantially less lean muscle, which is a risk factor for insulin resistance .< ref > Human metabolic processes were evolved in the presence of physical activity-rest cycles, which regularly depleted skeletal muscles of their glycogen stores .< ref > S. Boyd Eaton estimated that ancestral humans spent one-third of their caloric intake on physical activity ( 1000 kcal / day out of the total caloric intake of 3000 kcal / day ), and that the paleolithic lifestyle was well approximated by the WHO recommendation of the physical activity level of 1. 75, or 60 minutes / day of moderate-intensity exercise.

In the Southern Ocean, one species, the Antarctic krill, Euphausia superba, makes up an estimated biomass of over, roughly twice that of humans.

Scientists estimated that it would take a similar amount of time before humans adapted naturally to HIV infection in the way monkeys in Africa have adapted to SIV and not suffer any harm from the infection.

The use of a rat sequence also confirmed this topology and estimated date of divergence from the swine / human strains was 7. 44 × 10 < sup > 4 </ sup > years ago ( range 2. 1 × 10 < sup > 4 </ sup > to 1. 4 × 10 < sup > 5 </ sup > years ago ) Since this date is approximately coincident with the advent of agriculture it may be that this virus originally infected rats and subsequently spread to pigs and then to humans.
