Snakes on the Brain

Great editorial by UC Davis anthropologist Lynne Isbell in yesterday's New York Times about snakes and the evolution of vision in primates.

Isbell argues that "[n]ew anthropological evidence suggests that snakes, as predators, may have figured prominently in the evolution of primate vision — the ability, shared by humans, apes and monkeys, to see the world in crisp, three-dimensional living color." She offers this further proof: "The hypothesis draws further support from what we know about the evolution of raptors: Eagles that specialize in eating snakes have larger eyes — resulting in greater visual acuity — than eagles that don’t."

Opinion: Snakes on the Brain
There's a deep connection between snakes and primates, one that may have shaped who we are — and how we see — today.
