Forming a new species can be very tricky, however it is possible. This takes up time and also you need to breed one species with another specific species to get an end result. When it comes to reproducing, choosing a mate is very important. Also, there will be competition between all of the objects participating in this reproduction. Food resources are another very important thing to be aware of. A well known example of evolving into a new species is the Rhagoletis pomonella fruit fly.
