Humans and their domesticated animals represent 96% of all mammalian biomass on earth, whereas all wild mammals represent only 4%. [139] Estimates of the population at the time agriculture emerged in around 10,000 BC have ranged between 1 million and 15 million.

Comparing this to other mammals, it can be inferred that the first mammals to gain sexual differentiation through the existence or lack of SRY gene (found in the y-Chromosome) evolved only in the therians. Early mammals and possibly their eucynodontian ancestors had epipubic bones, which serve to hold the pouch in modern marsupials (in both sexes).
