human race

Good topic,it all happened due to geographical differences,genetic constitution for colour variations,shapes,heights etc.,but the problems like religions,castes created by human being only for his convienience to divide and rule in early ages of culture..The bad thing is still it is continuing rather increasing the problems which creating no peace or leading to wars also.....

Color is base don where you live. People who live in warmer climates have eveloved to have darker skin and tan easily. Caste and creed is because not every person is created equal or thinks the same and need something to differentiate themselves from the others around them.
