@edhollox [Such a tempting hypothesis.] Here's another gene duplication & diet story: https://t.co/j8TUp5JK2R. Mammalian - but not bird - blood feeding bat species have a duplication of the Plasminogen activator gene (serine protease that regulates blo

Vampire bat plasminogen activator genes (produce saliva enzymes that degrade blood clots) show positive selection w/loss of K2 domain = increased fibrin specificity & enhanced ability to feed on mammalian blood (& WWV bat likes mammal blood too) ht
