Chernoff Faces
What I learned about the classification of living things after doing the Chernoff Face activity was how most classifications start off as broad overviews but as we get more specific, there are less and less species alike.  For example, we started off by splitting up into groups where we had the same head shape.  Although it was more specific, there were still quite of few people in each group.  However, after we broke it down further by the shape of our mouths, there were about three or four in each group.  Another kicker from the activity was how in which ways we were looking to classify and how that affected the outcome.  Instead of starting with the classification our head shape, we did the shapes of our noses--I think--and the people in each group changed drastically from the classifications of just our head shape.  This made me think about all of the species in our world, but the first that came to my head was the population of birds.  Scientists could first start off by classifying birds by the shape of their beak, whether it'd be rounded or pointed, and then classify further by the sound of their pitch and how there would be still thousands of birds classified in those two categories despite being fairly specific.  Birds are just a prime example about how scientists need to use all of their senses in classify birds because there are so many that are similar to each other, but they may have slight nuances which make them different.

Here are a couple of the faces in the experiment.  They are similar but very different at the same time.
