What would happen if only females existed on Earth?

Answer 1

If only females existed on Earth, then there would not have been an possibility of generations as a woman alone cannot give birth.

This is a highly speculative question. If only females existed on Earth, it could be that the human race would die out in one generation, or it could be that there would be advances in the field of human cloning, and the human race would perpetuate itself by means of asexual reproduction. Even then, I would expect the global population to decline. There would be a tremendous number of other consequences, as well. For one thing, since women would no longer have any reason to make themselves appealing to men (who would not exist) the whole concept of fashion would be likely to change.
