Missing link in coronavirus jump from bats to humans could be pangolins, not snakes

As scientists scramble to learn more about the SARS-CoV-2 coronavirus, two recent studies of the virus' genome reached controversial conclusions: namely, that snakes are intermediate hosts of the new virus, and that a key coronavirus protein shares 'uncanny similarities' with an HIV-1 protein. Now, a study refutes both ideas and suggests that scaly, anteater-like animals called pangolins are the missing link for SARS-CoV-2 transmission between bats and humans.
