  • Pardis Sabeti of the Broad Institute in Cambridge MA recently developed a way to identify genes that played a key role in evolution. Her team has now gone further and put one such gene into a mouse to figure out how it changed human's ancestors. Humans differ in many ways, from skin color to immune systems. While some traits probably became widespread by chance, others gave their owners some sort of evolutionary advantage, and were therefore favored by natural selection. Sabeti's method can tell which was which by looking for features associated with natural selection. Sabeti examined the genomes of 179 people from around the world, and pinpointed 412 DNA regions that were selected for.
