Assume that a lineage of rainbow trout accumulates mutations over time that make the trout a uniform dark brown with orange spots and produce a dorsal fin shape that is very different from all other rainbow trouts. This group of rainbow trouts also has lips that are twice the size of other rainbows and they have a much narrower body. How do we know when the natural selection of such characteristics results in a new species of fish?
