Human evolution
Separation:
An earth quake happens and during so the earth cracks in Asia and most of the land goes under water and all there is left is a small island that is not roomy enough to fit every one.
Australia also doesn't go under water along with the United states.
Adaptation:
People start to have to go under water more and fish so they can eat because they ran out of resources for all those people. There is room running out on the island because people are still reproducing and they need room. People start growing bigger sets of lungs so they can be under water for longer periods of time. The start growing webbed feet so they can swim faster and not tire them selves out. Eventually they turn into mermaids and live under.
Division:
Eventually humans find the mermaids but can not reproduce because the mermaids have genetically changed how they reproduced.
