Chordata Memes

Behold the magnificent personality quiz of the deep sea! These translucent nightmares are actually sea squirts (tunicates) in their predatory form. Despite looking like rejected alien props from a sci-fi movie, these filter-feeding organisms are our distant evolutionary cousins! That's right—these gelatinous mouth-tubes share a common ancestor with vertebrates like us. I'm personally feeling like a number 7 today—ready to silently judge everyone while looking fabulous in my see-through body. Fun fact: some tunicates actually digest their own brains after finding a nice spot to settle down. Talk about the ultimate commitment to the homebody lifestyle!

Biologists really out here looking at a lancelet, a turtle, and a T-Rex saying "yep, same family reunion" but then freak out if two nearly identical worms diverged last weekend. The top diagram shows chordates (including us humans) claiming kinship with wildly different creatures because they share a notochord at some point, while the bottom shows taxonomists having an existential crisis over minor differences between worm-like creatures that probably couldn't even tell each other apart. The "point of divergence: before the big bang" vs "point of divergence: last weekend" is peak biological sarcasm. Taxonomy is just biologists playing favorites with their classification system while ignoring the screaming absurdity of it all.
