Based on the article and Mayr’s definition of a species, it is correct to say that coyotes (Canis latrans), wolves (Canis lupus), and dogs (Canis lupus familiaris) are separate species. The article mentions that in the past, and today, that all three species had the ability to breed with one another, but in Mayr’s definition there is an emphasis on “interbreeding natural populations.” In his article Kays says the last recent account of wolf and coyote mating took place a hundred years ago and was due to low numbers of wolves in the Great Lakes area. This forced both species to interact. The same occurred between dogs and coyotes as coyotes began moving east but could not find others and instead bred with feral dogs. Kays states that while interbreeding can happen, they are usually exclusive within their own group.

Next time make sure the paragraph is longer and legible because the characters are too small I can barely read it. You can also add more sentences to the paragraph it is too short.
If you reference a definition
If you reference a definition, it might be less confusing to a reader if you include the entire definition in your paragraph.

The sentence, "This forced both species to interact," seemed a bit awkward because it was so short. I'd recommend integrating it into another sentence. For example: "In his article Kays says the last recent account of wolf and coyote mating took place a hundred years ago. Due to low numbers of wolves in the Great Lakes area, both species were forced to interact."
