[QUOTE="rmwilliamsll, post: 22232081, member: 29694"] how do ring species fit into this definition? (is the relationship "is a species- transitive?) there is an additional problem with the word "can" in "that can produce fertile offspring", for instance, does that mean that corn with the Texas sterile gene is another species? or that two populations which never interbreed but can are still one species? for example, some insects which mature at different times never interbreed yet potentially can, yet are considered two species. defining species is not nearly that easy.
