What's a "lizard brain"?

24. It only took only around 3-4 million years, blink of an eye in geological time,

for evolution to turn something with the intelligence of a chimp into something with the intelligence of a human.

As far as birds go, they seem to have evolved different structures in their brains that perform similar functions to the mammalian neocortex.

I tend towards the view that humanlike intelligence is not as unique as we like to believe. I think there's a tendency among many to want to see ourselves as "speshul", and that this impulse can lead to some harmful and destructive behaviors.

I think there's just a philosophical divide that we're on different sides of, as I prefer to think of ourselves being a part of life on Earth, and our minds existing as part of a continuum with other creatures.

At least as far as bird brain question goes, it looks like the current scientific consensus is on my side.
