Eyes give insight into evolutionary arms race
..."If the development of complex life is viewed as 24 hours, everything
of interest happened in the first hour," he says. "Our fossils are
from that first hour. Within the first blink of evolution, animals had
evolved eyes that are very similar to what modern animals have today."
....Although the find is important because it is the first of its kind
to be found in such a preserved state, Lee says it is doubly
significant because the eyes are "so unexpectedly advanced".
