I just read about how coyotes and dogs can interbreed, and their offspring can also breed. I thought one of the classifications of species was that two different species could either not breed together, or their offspring would be infertile. Dogs are of the species canis lupus, and coyotes are of the species canis latrans; different species, yet they're able to create fertile offspring. So was I misinformed about the distinction between different species? Thanks.
