A large international team of researchers has conducted an extensive genetic analysis of lions, and in so doing, has learned about their evolutionary history. In their paper published in Proceedings of the National Academy ...
"Jumping genes"—bits of DNA that can move from one spot in the genome to another—are well-known for increasing genetic diversity over the long course of evolution. Now, new research at Washington University School of ...
