"So then, you believe there is a creation/evolution hybrid thing going on? Is my brain more complex than that of a Sparrow? So which part was created, and which part “morphed”."
Not really. My personal opinion is that the whole universe is a natural phenomenon, brought about by the laws of physics. Life is chemistry.
A sparrow is not a mammal. Your brain is actually somewhat more complex than a bird's brain. It is not, however, different in its components than that of a mouse. The human brain is larger and has more neural connections than that of a mouse, but the structures are equivalent. Different portions of the human brain are larger (comparitively) than the mouse's brain, but the various sections of the brain are made up of virtually identical components.
The bird's brain is more closely related to that of the reptiles. There are common structures, however, even in the bird or reptile brain and the human brain. The brain stem, for example, which handles some basic things, like the beating of the heart, etc., along with the fight/flight instinct, are quite similar in birds and humans.
>>A sparrow is not a mammal.<<
So, then, you believe that Sparrows and mammals have completely discrete evolutionary paths, going back to their very beginning root of "life from lifelessness"?
