More than likely, the infectious pathogens of early hominins and other animals evolved, due to climate changes, with their hosts to the present day and some became zoonotic pathogens.
Equus species possess widely varying diploid chromosome numbers, from 2n = 32 (Mountain zebra) to 66 (Przewalski's horse).
After having just photographed leopards, cheetahs and lions up close, I recalled the collaborations and publications with Steve O’Brien, Moritz Van Vuuren and Steve Osofsky on testing Africa’s big cats for the common domestic cat pathogens.
