Andrew Parker reveals why scientists now believe that the arrival of
creatures with sight kick-started evolution's 'big bang'
13 October 2004
Around 530 million years ago, in the Cambrian period, the animal
kingdom exploded into life. This was the time of the "Cambrian
explosion" - evolution's "big bang". Prior to this animals were all
soft-bodied, like worms, as they had been for the past 300 million
years. Then, in less than five million years, nearly all the major
animal groups on Earth today independently evolved hard parts.
