Abridged Whale Evolution chart

I was at oceanography camp and my group did our presentation on the evolution of whales from land to sea. Basically this chart shows the three main steps of whale evolution(this is not the whole evolutionary line, just three steps I felt most summed up the changes) Oh yeah, and if Judy sees this somehow, thanks for ruining finding Nemo for me with your presentation (I will never see that movie the same way) and I'M BATMAN!
