[edit]It is undoubtedly true that failure to consider phylogenetic relationships might lead to misleading results because of the potential problem of phylogenetic inertia. [1]
They represent average values and should only be considered as approximations. [2]
Numerous mammalian taxa exhibit reproductive delays, pauses in reproduction that occur between mating and fertilization, between fertilization and implantation of the embryo, or after an embryo has implanted. [3]
The conclusion is that the nine-month gestation period for humans is merely a matter of human size and not the result of some evolutionary optimization. [4]
In reproductively mature female mammals, an interaction of hormones from the pituitary gland and the ovaries produces a phenomenon known as the estrous cycle. [5]
