In sympatric speciation, groups from the same ancestral population evolve into . In order to be considered to be a single species in the biological species concept, a group of organisms must produce healthy, fertile offspring when they interbreed. This example of sympatric speciation occurred through habitat differentiation: apple maggot flies began to prefer apple trees as host plants, whereas their ancestors used hawthorn trees. In some case, organisms of different species can mate and produce healthy offspring, but the offspring are infertile, cant reproduce.

Speciation is an evolutionary process of the formation of new and distinct species. On the flip side, organisms that belong to the same species can look very different from one another. The definition of "species" is hotly debated among evolutionary biologists and none of the (numerous) proposed definitions seems to adequately cover all cases. (see, Hybridization is known to happen between what are generally accepted to be different species sometimes this leads to new species, other times some traits from one species become incorporated into another species. This question may seem silly for very different species (like a plant and an animal), but for others like the horse and the donkey above, it's much less obvious. https://teach.genetics.utah.edu/content/evolution/speciation/ Chapter 23 Practice Answers.pdf - Madeira City Schools Key.
