My current understanding of evolution is that of a “ripple effect” at first one or two individuals gain an evolutionary advantage then pass that trait own to offspring thus multiplying the number of evolved individuals. As the number of evolved individuals increase the number of non-evolved individuals decreases thus for a short time (a few hundred years) there is a co-existence of both non-evolved and evolved.

To explain how one species splits and evolves into two seemingly different species is left to the fact that almost all animals current and prehistoric migrate until they find areas suitable to sustain them. Even in modern day animals it is true that when a large group of animals migrates not all of the animals choose to leave a give area thus leading to different paths of evolution. Obviously an evolutionary advantage in one area may not and usually does not translate to an advantage in another area.



As for finding research to back up my previous statements of the scaled and feathered raptors it will be a few days because I am having to go out of town for work but I will post my findings ASAP.
