Evolution & Taxonomy Nerd Hats

Carcinization is the name for the way crustaceans keep evolving into crabs. Know Your Meme says crustaceans have taken the crab shape at least 5 independent times, and PopSci reports the crab form has evolved so many times that scientists had to come up with a special term for it. That is the in-group this page is for. Cladists have a favorite correction of their own. ScienceAlert's version: for a cladist, either there is no such thing as a fish, or we are fish too. And by the cladistic definition, birds are dinosaurs, the same way bats are mammals. These evolution and taxonomy hats put those corrections on a dad hat. Two badges name the trade, EVOLUTIONARY BIOLOGIST and TAXONOMY NERD. The rest are the pedant's one-liners: the bird correction, the fish admission, the crab meme, a taxonomy label with an attitude, a fruit-relative claim, and a deadpan four billion years of history with the wearer as the result. BIRDS ARE DINOSAURS already appears on TeePublic hats, so it gets a second colorway, and so does the crab line. Every design is custom embroidered on an unstructured dad hat. Wear one to the field station, the faculty meeting, or any thread where someone just called a crab a crab.
