Why do humans menstruate when most animals don’t?
In: Biology
Because we weren’t meant to live like this. Humans evolved constantly underfed and females were pregnant most of the time from maturity to death. This had a huge toll on their bodies and there was no extra energy for “periods”. Combined with not having a specific mating season, it was a good enough system. Now, women’s bodies have way more rescources and are rarely pregnant (compared to then) so this tiny backup mechanism in our biology to quickly flush out the gunk has become a huge painful part of women’s everyday lives. So it’s basically a side effect of our changed lifestyle and how society evolves faster than biology.
