What makes an organisms advanced or complex is by comparison to
another organism with respect to a specific feature. Humans have very
complex brains but rather uncomplicated digestive systems compared to,
say, ungulates.
What is important is to remove the notion that humanity is somehow the
primary goal of the evolutionary process, that we are the star on the
top of the christmas tree so to speak.

The Dragons of Eden is a very entertaining work but it not a good
reference for DNA or the brain as it is at least 15 years out of date.
Telling Alex to read _The Dragons of Eden_ is somewhat like telling a
particle physicist to read _The Tao of Physics_ for a reference on
quantum mechanics.
