The gestation period in humans is relatively high, compared to some other animals out there, and actually varies by race and ethnicity. But many other animals have much higher gestation periods. Manatees, for instance, carry for 15 months. Camels carry for over a year. Giraffes carry for a year and a half, and elephants carry for nearly two years. Gestation periods are dictated by natural selection; e.g. how long it takes the embryo to develop into a viable fetus that can survive on oxygen and nutrients from milk.
