      Excellent question. At fist everything reproduced asexually so there was no distinction between male and female, and organisms just sort of cloned themselves. Sexual reproduction is advantageous because it allows the genetic mixing of two lots of DNA which allows for a greater instance of mutation which speeds the process of evolution up and organisms can adapt quicker, which is useful when the environment is changing quickly.
