New York’s Evolution store specializes in natural history objects such as skulls and skeletons, fossils, minerals, antique anatomical charts and so on. The centerpiece of their inventory is a series of teaching-grade and museum-grade replica skulls of early hominids made from sturdy resin and plastic. I bought one of these today — it was one of those things that you only realize that you’ve been looking for it all your life at the moment that you clap eyes on it. Pictured here, a teaching-grade replica of a Australopithecus africanus, a human ancestor that lived 3.3 million to 2.5 million years ago.
