Canis latrans, Canis lupus, and Canis lupus familiaris are three different species. According to the article, Yes, eastern coyotes are hybrids, but the ‘coywolf’ is not a thing, by Roland Kays mentions that Canis latrans are hybrid species composed of three genetic swapping among the three types of Canis groups. Each type of them have a separate ratio of how much each gene it is composed of. The article writes that the three species are biologically possible to interbreed with one another but preferably not to mate with each other. I think this is the vital part which supports that these species are no longer the same because within a population, species will not have an urge to kill one another within the group. However, the fact that these three species will exhibit enmity is a strong evidence that they are separate.

Maybe just fix this sentence,
Maybe just fix this sentence, "According to the article, Yes, eastern coyotes are hybrids, but the ‘coywolf’ is not a thing, by Roland Kays mentions that..." and delete the "by".
Suggestion
Avoid saying "I think" in science writing. It is too informal. If you wish to express doubt about a claim you are making, clearly explain why.

There should be greater evidence for your claim that the same species tend not to kill one another. Furthermore, the concept of species is defined by which species concept is being reffered to. Your argument may be stronger if you set the definition straight in the topic sentence.
