Why is pregnancy longer in elephants than in humans??

Answers (1)

Elephants have the longest gestation period out of all the animals. They carry pregnancy for more than one and half year that is 18-22 months. They are able to carry their young so long because they create more of the temporary glands that monitor hormone levels during ovulation and pregnancy.In elephants\, things are quite a bit different. Instead of creating just one corpus luteum they create on average five.Therefore , the glands don’t all form at the same time, they arise over time. As one gland begins to slow its production of progesterone, another is created to take its place, and this is how the elephant manages to keep a baby going inside of it for so long.
