1. How does the story of the Brodies' work demonstrate the power of evolutionary

Based on the story of Newts and Snake,an the emergence of toxic poison in newts,it shows that evolutionary change  can be outstanding with  a significant effects especially  when two families  involved are at war with one another.

Most importantly it shows that the  evolution  that occurs now is a follow up of the millions of evolutionary history which occurs million of years ago in history.Some evolutionary changes did not occur in the past because of blockages of   some  the right pathways, while some  evolutionary pathways  opens because  right things occurs.
