Lab #8 Darwin's Dilemma

The video explores Darwin's dilemma which was that his theory of gradual evolution is not supported by the fact that the fossils he found seemed to have been formed almost at once.  The evolution was not gradual but rather sudden and is called the Cambrian Explosion. The duration is not known and it raises huge questions, it could have lasted from one day to many years.  These findings have stirred up massive debate which challenges Darwin's theory.  Southern China seems to have a lot of fossils in mint condition that can be examined, and there are some fossils from before the Cambrian explosion that can help explain how this came about.  Darwin's theory while viable  is not the only one out there and many people adhere to it so that any other theory seems to be pushed to the wayside.  I don't know what to believe anymore. Evolution is still a lot of theory.  "Nature takes no sudden leaps" is a famous quote from Darwin which is being challenged by this
Cambrian Explosion.  It seems some sort of biological catalyst was introduced that jump started all of these species.
