Listen up all of you would-be claspers.
The first rule of thumb to remember is that our (Males) buttons, snaps, fly flaps are all the right side of our clothing. The female's are all on the left. (Do not know the reason, but I'm sure someone here does)

Archeologists and Anthropologists have recently discovered that Buttonlapithicus was an genderless society. There were no distinctions between male and female (except reproductive organs), which were concealed beneath their non-descript clothing. Buttonlapithicuses looked so alike that male and female were often confused and during mating rituals often found themselves in bed with their same-sex, which of course inhibited reproduction. As homo-sexuality increased, population decreased to the point that the Buttonlapithicus society neared extinction! So, the smartest of their group, what we would call Men, devised a system of button wearing that separated the sexes.
So, you see, it has to do with survival of the fittest and evolution.
