I found this on a web site and thought you guys would find it interesting. Also could you explain how this works in the context of gradualist evolution.
"The punctuated reality of the fossil record is best exemplified by the "Cambrian explosion." Virtually every animal phyla (including chordates and many phyla now extinct) appeared during the short geological moment called the Cambrian explosion (13). This period of time is now known to have covered a period of time of less than 10 million years (14, 15). The diversity of life and the variety of body designs has led Stephen Jay Gould to make the following statement:"
"We have reason to think that all major anatomical designs may have made their appearance at that time."16
