re: #148 SixDegrees
New species are certainly one result of evolution. But they are not it’s only product. The accepted definition is simply that of a change in a population’s genetic makeup - there’s no distinction made between large changes (the addition or subtraction of genetic information) and small changes, such as as a simple shift in frequency of certain genetic elements. It’s all evolution.
