What major biogeographic event is cited as evidence for Musteloidea superfamily incursions into South America?
Answer
The Great American Biotic Interchange (GABI)
The migratory history of the Musteloidea superfamily involved widespread movement across continents. Evidence of their spread includes incursions reaching into South America, a dispersal event specifically linked to the Great American Biotic Interchange (GABI). This interchange involved the substantial exchange of terrestrial fauna between North and South America. Although the main radiation of the *Mustelidae* family was established before GABI significantly shaped modern distributions, members of the broader superfamily utilized this connection to establish a presence on the southern continent, showcasing the wide dispersal capabilities of these ancient carnivoran forms.
