Evolution in action: Our antibodies take 'evolutionary leaps' to fight microbes
Date:1/5/2009

ns), it caused several mutations at once (cluster mutations) in the DNA, adapting our antibodies for a rapid and effective response to a new microbial invader.

"As the planet warms, infectious diseases may be one the biggest threats to human survival," Weissmann added. "Nowadays, mosquitoes, parasites and viruses cause diseases in the United States that were once isolated to warmer parts of the world. They evolve, and - a la Darwin - so does our immune system each time we meet a new microbial invader."
