In this seminar we will explore the exciting story of Yellowstone’s beloved evolutionary cousins: gray wolves (Canis lupus) and coyotes (Canis latrans). While fossils suggest that these two species diverged over a million years ago, more recent genetic analyses suggest that that this divergence may have been as recent as approximately 50,000 years ago – just a blink in evolutionary time! Yet while many similarities exist between these two species, important ecological and behavioral differences occur too. Gray wolves are distributed throughout the Northern Hemisphere (North America, Europe, and Asia), whereas coyotes are a true American species, found only in North and – now – Central America. Gray wolves will always seek out and spend their lives in social groups, while coyotes can live as solitary individuals. Both species were targeted throughout the 19th and 20th centuries in US predator control campaigns, but though gray wolf numbers plummeted, teetering on the edge of extinction in the US by the 1960s, the distribution of coyotes has continuously expanded over the past 50+ years. What accounts for these differences? Just how similar are they? In the field, lecture, and film we will explore the evolutionary history of coyotes and wolves, observe and discuss their similarities and differences, and gain a rich appreciation of the behavior and ecology of these two iconic Yellowstone canids.
