Beginning around 6:45 listen for the "continually advancing stages of the brain."
Humans quite literally have reptilian brain contained in their brain.
It's true! Why would humans bother inventing a new machine to control breathing and moving and stuff. Much more economical to upgrade then rebuild a system of this complexity.
Our cerebral cortex is ridiculous. It's like the ultimate absurd logical extension of what a cortex could become. It's a massive sheet of very thin layered processing area packed into a really small space. This is literally why it is so wrinkly. Birds have some cerebral cortex too but its just a tiny smooth bump in front of their lizard brain. But they get to fly so don't feel bad for them
Mammals are the best at making cortex. We can make it faster because we're warm blooded and we can make it longer by brewing it in a womb. Humans take this to the extreme. Cortex development begins really early so it can go as long as possible and it continues for over ten years after birth. Cortex totally dominates the skull while the core body running gear has been miniaturized. Your midbrain and hindbrain is just as big as T-rexs! Remarkable!
I love phylogenetics! The tree of life is a very beautiful and unifying concept IMO. All creatures are related to us in the same spreading causality wave.
this is a fun phylogeny website:
http://www.tolweb.org/tree/IMO, the diversity of our living relatives is the most amazing and beautiful thing in the known universe. Too bad we're causing a mass extinction
