maybe i am wrong....but i was always
under the impression that significant natural evolution requires 
small isolated communities / populations
of the said organism, where the isolation is at least a period 
of measurement in terms of centuries
rather than years... (in the case of larger organisms like 
mammals...), clearly there are no such
isolated human communities anymore...
