The Joke

The comic is titled "The Evolution of Consciousness" and presents a series of six panels, each showing a brain (or brain-like organism) at a different stage of cognitive development. The stages progress as follows: (1) "Can react to environment" -- a simple blob. (2) "Can imagine environment" -- a slightly more developed brain. (3) "Can imagine other minds in the environment" -- the brain is getting larger. (4) "Can imagine own mind" -- self-awareness emerges. (5) "Can imagine murdering in cold blood for purely social reasons" -- a fully developed human brain. (6) In the final panel, a human proudly declares "I'm the pinnacle of all biology!"

The Humor

The comic sets up what appears to be a straightforward, ascending hierarchy of consciousness -- each stage seems like a genuine milestone in cognitive evolution. The reader expects the progression to culminate in something noble or profound, like abstract reasoning, art, or philosophy. Instead, the penultimate stage is the ability to contemplate premeditated murder for social reasons (jealousy, status, revenge), which is presented as the crowning achievement of the human brain.

The final panel delivers the second punch: a human smugly declaring themselves "the pinnacle of all biology," completely oblivious to the fact that the comic just established that humanity's most distinctive cognitive ability is cold-blooded, socially motivated violence. The joke is a dark commentary on human self-regard -- we pride ourselves on our advanced consciousness while ignoring that much of our higher cognition is devoted to decidedly ignoble purposes.
