One has to be careful of the words: "basic" and "exactly". The brains
of dogs and humans are basically the same and are not exactly the
same. They are both called "brains" (that's a good start for their
sameness) and a glance at them on the dissection table will reveal
similarities. But closer examination will reveal many differences
too, accounting for species differences in muscle control, the senses,
abstraction, etc. There are also similarities, which make the study
of animals a valid way of studying humans.
But what I'm trying to say is that the "brains" will define the limits
of capability of the characteristics of behavior specific to the
species; and, to this degree, brains are different, not only between
species, but between individuals. I'm just trying to build on what
the original post delineated regarding inherent (DNA is the way he put
it) characteristics of the brain.
I have seen people argue that all brains are equal and identical. It
seems to be a religious issue.
