annoying nitpick
There is no progression up a ladder in evolution, not towards sophistication nor complexity.
Every single species alive on earth comes from a genetic lineage precisely as old and thus “evolved” as we do. Species can shed complexity and capabilities from evolutionary pressures just as much they can gain them.
I know this is a meme but framings subconciously slip into our ways of thinking like this very easily.
My point is about the conceptual framing of a ladder leading to a narrow frame of view about evolution, not that this particular meme is portraying itself literally as an evolutionary ladder.
