Miami has 100s of acres of beautiful Natural Areas which lend themselves to research projects! (Quicktime movie~4 mb). On the same walk, I spotted my first garter snake of the spring! In another 1 mb quicktime movie, a pair of mallard ducks lands in Harkers Run in Bachelor Woods

I decided to change my research idea because I felt that the deforestation was too broad of a topic. The sloth was an interesting creature and unique to the Central American region unlike deforestation. I also choose the sloth because I was honestly curious how a creature that is that slow could have survived through evolution. I would have thought that something like that would have died out through natural selection a long time ago. I did this paper to find out to find out why my assumption that natural selection should have run its course long ago is false, I think the reasons behind it will be fascinating.
