Studying Evolution can teach us a lot about the animals around us here in Alaska, how they survived under certain environmental conditions, and how the world has changed with all the different biomes that occurred during continental drift.  

Confirming evolutionary timescales across many species might help understand the timescale of speciation processes like chromosomal synteny.  

The Earth was not created 6000 years ago...it is billions of years old.  There was never a great flood that could have caused the extinction of a freshwater dolphin.
