Interesting. Humans got the common cold virus from camels.

     I got this info from Trivia Genius (https://www.triviagenius.com/) which sends me trivia emails each day.

The dawn of human civilization was a boon for many pathogens, which thrived thanks to the close proximity of so many potential hosts. It's not simply that humans started gathering in towns and cities; it's that they began domesticating animals. Influenza is believed to have originated in birds, HIV in chimps, Ebola in bats, and new research indicates that the common cold came from camels. Scientists figured this out while researching Middle East Respiratory Syndrome (MERS). Scientists tested 1,000 camels to confirm that they were the source of the outbreak and found cold virus pathogens that can infect humans in several subjects. Although the human immune system has developed protections against the cold, making it relatively harmless, the same is not the case for MERS, which is in its early stages of evolving to be able to infect humans. This means that it is not always easy for it to pass from a camel to human, but when it does there's a high mortality rate because our immune systems are not primed to fight it off.
