Gonorrhea. Bed bugs. Weeds. Salamanders. People. All are evolving, some
surprisingly rapidly, in response to our chemical age. In Unnatural Selection,
Emily Monosson shows how our drugs, pesticides, and pollution are exerting
intense selection pressure on all manner of species. And we humans might not
like the result.
Monosson reveals that the very code of life is more fluid than once imagined.
When our powerful chemicals put the pressure on to evolve or die, beneficial
traits can sweep rapidly through a population. Species with explosive population
growth—the bugs, bacteria, and weeds—tend to thrive, while bigger,
slower-to-reproduce creatures, like ourselves, are more likely to succumb.
