Homo sapiens

Unique characteristics of human reproduction and life history traits

"...humans exhibit relatively low per-copula fertility in association with concealed ovulation, an especially invasive form of hemochorial placentation coupled with copious mensruation compared to other primates, and remarkable fatness in babies, well beyond that of other mammals. Finally, humans have evolved substantial alterations in life history, with neurologically precocial yet physically altricial infants, remarkably short interbirth intervals despite the high cost to mothers of fetal development, a relatively elongated childhood, a greatly extended adult stage, and a postreproductive period in females associated with alloparental care."
