Evolution of venom, binge eating seen in snake DNA

Python and cobra genes evolved quickly to enable hunting strategies

Snake genes are in high evolutionary gear.

Complete genomes of the Burmese python and king cobra reveal that many snake genes have changed more rapidly than those of other vertebrates, researchers report December 2 in two studies in the Proceedings of the National Academy of Sciences.

The two genomes are the first complete sets of snake genes ever assembled. 

Snakes evolved some extreme survival strategies. Cobras and pythons represent some of the most out-there examples, says David Pollock, a c...
