Just got an audience with the creator, gave you an opportunity to choose one organ to enhance/reduce its functionality; Cause apparently the creator can “grant your wish”
- what organ would you choose?
- what functionalities would you add/deduct?
- why such?
The tldr is not every species with a uterus menstruates.
Most animals’ bodies don’t convert into a child bearing state until they’re already pregnant. Dogs and cats for example don’t grow breasts (or line their uterus) until they’re pregnant. Humans (and a few other species) evolved to just be ready to raise a child at any time, which results in permanently developed breasts and a continuous refreshing of a uterine lining.
