Reflection on the film “What Darwin Didn’t Know”

The film “What Darwin Didn’t Know” explains the advances that have been made in evolution since he passed.  With new technology scientists have been able to find exactly which genes between and within  species have mutated and changed. Through knowing which genes have changes and how great the changes are, scientists are able to figure … Continue reading Reflection on the film “What Darwin Didn’t Know”
