Evolution

Just received a wonderful letter from a friend that inspired me to think of a new theme:

Evolution

This word has an interesting flavor this month.  For some it is an incredible challenging concept to embrace.  The challenges could be based on one's faith or it could also be based on one's physical structure. Evolution could also be a process that one embraces and invites into their lives. For this post I want to focus on the physical structure, then expand, or evolve if you would like to say.

While waiting for crews to return to Sunset Island this evening, I found a pair of Horse Shoe Crabs mating on the small beach that faces Chokoloskee Bay.  These creatures who have compound eyes located on the front of their shells and 5 more addition eyes located from head to tail.  A creature that has remained basically the same since the Paleozoic Era.  The world around it evolving.  The birth of flowering plants, amphibians, humans have all come to life, while the humble Horse Shoe Crab has remained the same.  The blood that courses through their systems also protects humans by preventing harmful bacteria from being introduced into ours.  

How does this creature remain unchanged for over 350 million years?  How does it not evolve?  A world spinning and changing and the Horseshoe Crab plows it's way through history doing it's thing.
