The wolf, dingo, dog, coyote, and golden jackal diverged relatively recently, around three to four million years ago, and all have 78 chromosomes arranged in 39 pairs.[6] This allows them to hybridize freely (barring size or behavioral constraints) and produce fertile offspring.
> Coyotes are closely related to eastern and red wolves, having diverged 150,000–300,000 years ago and evolved side by side in North America, thus facilitating hybridization.
