contracted a potentially fatal disease usually only known in birds.
Given the rapid reproduction rate of micro-organisms I suspect that
they have the ability to evolve faster than macro-organisms.
I wonder why people don't study evolution in microbes rather than
creatures like anole lizards? It probably wouldn't take 30 years to
