Canis lupus familiaris (dogs), Canis lupus (wolves), and Canis latrans (coyote) are very similar animals, and often a topic of conversation if the species are under one species or separate. Although, these animals are different species, and should never be considered the same species.  Those who are in favor of the three animals being considered the same species, base that assumption because these three animals are able to interbred with each and produce viable offspring, which in past years was a sign that organisms are considered to be part of the same species. However, in an article Yes, eastern coyotes are hybrids, but the ‘coywolf’ is not a thing, the author points out that different species do not have to be completely reproductively isolated, as that notion is now disregarded by zoologists in present time. The article points out that in times when both the species of Canis lupus and Canis latrans were underpopulated and endangered that the different species would mate with each other along with the other species Canis lupus familiaris. Although, when each species is not in endangered they choose to mate with their respective species instead of interbreeding with other species. Therefore, because the animals choose to mate within their own type when there is no risk of extinction, shows that each animal is in different species. 



This is an interesting topic, I didn't know this was such a hotly debated subject! However, in the first sentence, it would have been better if you said "and often a topic of conversation IS if the species..". Adding an "is" in this context makes the statement flow much better.

in the last sentence, you say that 'the animals choose to mate within their own type' and I think that in scientific writing you should try to substitute 'animal' and 'type' for more scientific phrases such as species, taxon, subspecies etc.. 

I thought this was really interesting! I also agree that the last sentense should use more of the scientific nomenglature. Also the content was very interesting! Great job!
