Scientists can create new species in the lab by controlling he individuals that mate. this is also done in agriculture under the name of animal husbandry. speciation that occurs through this method is called

When Scientists, farmers and/or breeders allow only individuals with certain characteristics (desirable characteristics for a given purpose, i.e.: bigger fruits in some plants), this will result in the formation of new species by a process called Artificial Selection; because people, instead of nature, selects wich pairs of individuals will reproduce.

There is a large number of examples of this speciation process that we can point out: dogs are the result of the process of selecting only the most docile and manageable wolves of the breed.
