... survival. "When we lose this vine, this beautiful butterfly
dies off with it, and we'll never see it again except in photographs at museums," said Proctor. "And when that happens, it can never be recovered." While this new research has implications for theoreticians who calculate endangered species, the moral...

Altered expression of key developmental genes underlies evolution of butterfly wing patterns
...rs studying gene expression in a range of moth and butterfly
species report this week that a certain class of wing patterns has likely evolved through seemingly simple alterations in the timing of various types of gene expression. The class of wing patterns in question, so-called "intervein" patterns, have lin...
