Evolution in a Big City
Using a tiny portion of the world as an example, Jason Munshi-South explains how cities have altered the genetic makeup of the animals living in them. Yip, salamanders living on either side of two bridges connecting the Bronx with Manhattan have different DNA sequences, because of the man-made infrastructure. Mice who were confined to certain forested areas have evolved differently to mice of the same species in other areas of the country. It’s an interesting talk, all demonstrated in beautiful photos and illustrations.
