When did almost all animal phyla diverge?
Solution
According to theory of cambrian explosion, beginning some 545 million years ago, an explosion
of diversity led to the appearance over a relatively short period of 5 million to 10 million years of
a huge number of complex, multi-celled organisms. Moreover, this burst of animal forms led to
most of the major animal groups we know today, that is, every extant Phylum. It is also
postulated that many forms that would rightfully deserve the rank of Phylum both appeared in
the Cambrian only to rapidly disappear..
