Google Doodles are meant to be fun and informative, but lately they've been cause for outrage.

Tuesday's Doodle is no exception. It features a primate, an Australopithecus (a close relative to humans) and a human, to celebrate the 41st anniversary of Lucy the Australopithecus' discovery. Lucy is thought to have walked upright and is considered to be an early human ancestor.

Forty-seven of Lucy's 206 bones were found in Ethiopia in 1974 — about 40% of her skeleton.

Evolution, of course, is an aggressively disputed topic (remember the Scopes trial, anyone?) and some creationists — and, probably, a few trolls too — have taken to the Internet to express their anger at Google for celebrating a historic scientific moment.

"Google, I'm not a monkey!" one wrote.

Another: "Google supports the THEORY of evolution. If evolution were true we wouldn't have monkeys around anymore, idiots!" (This idea is, of course, false.)
