The divergence of the two species will generally take place over a long period of time, and it can be the effect of differences in things such as diet, behavior and mate selection. This is a relatively uncommon form of speciation, though it has been observed in hawthorn flies and orcas. Though not common, sympatric speciation is an important evolutionary process that can separate a species into two new ones. They also have very different behaviors and feeding habits, which is what is believed to have led to the divergence, or separation, of the original species. There are two types of orcas that inhabit the same area, but they don’t interact or mate with each other. Both males and females prefer to mate and lay eggs on the fruit they came from, so there is little mating interaction between the two groups, and they have been separate long enough to have developed some genetic differences.Another example of sympatric speciation in animals has occurred with orca whales in the Pacific Ocean.
The ancestors of hawthorn flies used to lay their eggs exclusively on hawthorns but now lay their eggs on both hawthorns and apples. The hawthorn fly is an example of sympatric speciation based on a preference of egg-laying location. Over a long enough period of time, an entirely new species might develop. As they continue to mate with other members of their new group, these variations will become more prevalent in the population. Each new population of flies will have genetic variation in its gene pool, which is the collective genetic information for the group. Sympatric speciation occurs if interactions are so limited between these groups that mating no longer occurs between them. At first, all of the flies feed on red apples, but at some point, some of the flies begin to prefer green apples. There are two sources of food for them to choose from: red apples and green apples. We’ll start with a group of flies that are all the same species. This can happen in a variety of ways, but let’s look at a hypothetical example to understand the process better. You might be wondering how one species can become two separate species, even though they still live in the same area. This process allows new species to evolve from a common ancestor, while the new and old species are still living in the same geographic region. When this happens in nature, it’s called sympatric speciation. Eventually, you might even evolve enough to feel that there are more differences between you than similarities.
