Cambrian explosion

Read about Cambrian explosion.
Hundreds of millions of years ago, all of a sudden, huge number of animal phyla and species appeared like from nowhere. It seems like all the basic body designs were tested then. Any creatures, from earthworm to you, use the architecture first experimented during this eventful period.
There must have been a tremendous number of body designs that had failed to be passed on to the next generation. Evolution is a history of massive removal followed by differentiation within a few lucky surviving stocks, rather than the conventional tale of steadily increasing smartness, complexity and diversity. Among those blessed ones, you and me are here now having been created according to the blueprint that fortuitously has not been removed. Thank god.
