I can?t see a diversification of the human species occurring, if a sub-species began to develop and was recognised the scientific community would be fascinated but the rest of the population would be scared ("It's an abomination" or "its so sad we must help") because of sapience we won't let this happen, its basic xenophobia and either we all evolve together or we stay as we are.

Ohh! I?m not a biologist so gave me a hand. Is inelegance an evolutionary fluke or do many evolutionary paths lead to it eventually?

If you believe everything you read, better not read.
