Thanks Phi for All, I did look at that post but didn't find anything about the viability of humans. I hadn't considered this point, certainly a great point. Everything else I have learnt has refuted what you have said, yet it makes more sense using other examples in nature. Can evolution still occur even though humans are not isolated to one particular environment? A teacher said evolution can not take place within the human race because reproduction isn't limited to a certain evironment due to advances in technology.This means no human needs to evolve to adapt to a certain environment. is this correct? Thanks.

It is sometimes argued that advances in the medical science, by reducing the mortality due to hereditable diseases, result in building a reservoir of unfavourable genes in the human population, and that this will reduce the viability of the human species. Discuss this statement. I have read a few blogs on this topic but none explain about medical science reducing the viability of the human species. Can you please help me out here, it would really help gaining an understanding of this. Thanks

Hello Im Browne and I'm new can anyone tell me how to post something for people to discuss so a gain a stronger understanding of a topic? Thanks.
