The Cambrian Explosion!
About 540 million years ago, life experienced a dramatic increase in diversity during the Cambrian Explosion. This period saw the emergence of complex body structures, such as exoskeletons and segmented bodies, which gave rise to many of the animal groups that still exist today.
The evolution of vertebrates began in the oceans with fish-like creatures that developed spinal columns. Over time, some vertebrates adapted to life on land, giving rise to amphibians and later to reptiles, birds, and mammals.
