Greenbeards have blue throats in a breakthrough study of the evolution of altruistic behavior
A new study of side-blotched lizards in California has revealed the genetic underpinnings of altruistic behavior in this common lizard species, providing new insights into the long-standing puzzle of how cooperation and altruism can evolve. The study, led by researchers at the University of California, Santa Cruz, offers the first evidence in vertebrates of an…
