Abstract - “Ancient vision and the cause of the Cambrian explosion”
Suddenly,
and for no obvious reason, the range and variety of animals erupted
around 530 million years ago. This was during the Cambrian period,
and it represents life’s ‘big bang’. On a seemingly
separate subject, the first animal to evolve vision was a Cambrian
trilobite, a distant relative of spiders and shrimps. Before long
it had also evolved swimming capabilities and strong, grasping limbs
and mouthparts: it had become an active predator – in fact,
the first active predator, with visual search capabilities. If the
first eye is added to the geological timescale, the order of events
becomes the introduction of vision, first, followed closely by the
Cambrian explosion, second. Maybe this is more than mere coincidence.
