Are you familiar with the Cambrian Explosion?

Nigel Eves Actually it was an eighty million year event, hardly a flash in the pan!
"Paleontologists are gradually abandoning the misleading and outdated term “Cambrian explosion” for a more accurate one, “Cambrian slow fuse” or “Cambrian diversification.” The entire diversification of life is now known to have gone through a number of distinct steps, from the first fossils of simple bacterial life 3.5 billion years old, to the first multicellular animals 700 m.y. ago (the Ediacara fauna), to the first evidence of skeletonized fossils (tiny fragments of small shells, nicknamed the “little shellies”) at the beginning of the Cambrian, 543 m.y. ago (the Nemakit-Daldynian and Tommotian stages of the Cambrian), to the third stage of the Cambrian (Atdabanian, 520-515 m.y. ago), when you find the first fossils of the larger animals with hard shells, such as trilobites."
Nelson The previous commenter was being slightly dishonest in his comment. In geologic time the Cambrian period is aptly described as explosion - having occurred over such a relatively short period - and yet almost all present animal phyla appeared during this time.
