Brown Tree Snakes' Hidden Genetic Edge | Science News

The brown tree snake’s takeover of Guam is a biological thriller — scientists once thought a few accidental arrivals would be too inbred to survive, but new DNA research reveals over 19,000 genetic differences, especially in immune and smell genes, giving them an evolutionary edge. This hidden genetic diversity explains their explosive adaptation and resilience — bad news for eradication efforts, but a hopeful blueprint for saving other endangered species struggling with small populations. The next big question? Were these genes already there — or did they evolve on Guam? Listen in comfort:Get a discount on a Soli Pillow: http://solipillow.com/discount/dnn.
