We always start with the simpler animal, not that one animal changes into another but we look at the simplistic organism then we move to more complex organisms and through dissecting we hope to see that there's  an in structure for those specific systems. So for example respiration the simplistic animals go through diffusion and then they might have a real simple gill structure and then eventually the more complex that animal is the more complex that structure is so. More complex animals are going to have lungs. So by doing various dissections we can see that increase of complexity of the structures.”

Why is learning these things important? “I think the main thing is that humans tend to, and I've said this in bio 3-4 too, put ourselves up on a pedestal .
