This meme brilliantly merges quantum physics with evolutionary biology! The double-slit experiment is physics' greatest mind-bender - particles behave as waves when unobserved, creating an interference pattern, but act like particles when measured. Here, a horse transforms into a zebra through the quantum barrier, referencing the extinct quagga (half-zebra, half-horse creature) mentioned in the title. It's basically Schrödinger's equine - the animal exists in a superposition of horse and zebra states until someone peeks. Quantum mechanics: making evolution work at light speed since 1927!
