What would the effects (implications?) be if every male and every female in the world looked exactly the same?

This afternoon, while watching a sports program, I saw a cyclist who had a very big nose a bit like these ones in Frasier.
Suddenly I thought it strange that we all look different from each other.
That made me think of the following question:
What would be different in the world that we know now, if all men, and all women (the men and the women would look different from each other), looked the same same face, same body, same height, same weight, same odour…, everything exactly the same.?
For example, bullying would be history (or would it?).
Other things that you can think of?
I put it in Social, because humor is always appreciated, but some serious, well thought out answers are welcome!
