I thought our discussion of how to classify life in class was very interesting. I had never really thought about this before, so when the question was posed to us in class I thought it would be really easy to answer. After class, I started to think about what seperates humans from other organisms, or even if humans can be seperated. I have heard before that humans have a higher level of consciousness, but how is this measured or defined? How do we know that other animals don't communicate with the same complexity?
