Question

Why would a diverse population be more resistant to the disease, predation, and invasion?

(Sum it up for me)

anonymous · Answer

resistant to disease because people are immune in adapting different things.

anonymous · Answer

resistant to invasion because different people from different cultures will likely be in good terms.

anonymous · Answer

Would that still apply in the terms of organisms?

anonymous · Answer

a diverse population would be more resistant to these factors because, the organism number of species in a population can accomadate for losses by predators, resistant to disease because of the high tolerance range each member possesses, different immunity to different diseases and a more diverse  population tend to out-compete other invasive species gaining dominance

Thank you, that was a great answer. Very specific. :)

anonymous · Answer

Mind summing it up for me though? I have limited space.

anonymous · Answer

Ok, no problem!

anonymous · Answer

Could you sum it up smaller for me though? Not sure how to.

anonymous · Answer

A more diverse gene pool increases the chance that there will be beneficial mutation and thus protects the entire population against extiction due to diseases due to lack of a certain immunity factor, i.e. a greater T-cell number or the ability to produce a certain antibody.
