Science: Fear of Snakes May Have Driven Pre-Human Evolution

"An evolutionary arms race between early snakes and mammals triggered
the development of improved vision and large brains in primates, a
radical new theory suggests. The idea, proposed by Lynne Isbell, an
anthropologist at the University of California, Davis, suggests that
snakes and primates share a long and intimate history, one that forced
both groups to evolve new strategies as each attempted to gain the
upper hand. Early primates developed a better eye for color, detail and
movement and the ability to see in three dimensions - traits that are
important for detecting threats at close range. Humans are descended
from those same primates. "
