How are they determined to be new species and what are some specific examples of how they evolved?

  5. Our brains are very complex machines, and in some ways, we still do not understand them. How does the physical brain give rise to human consciousness? Can this be explained by neuroscientists, and how did this come about? Are other organisms conscious? For example, insects do not feel pain, but many animals are capable of a wide range of emotions. How does our knowledge of the body relate to the philosophy of the mind?
