The Kickstarter Animal of the Day: Glyptodon!, one of our favorite prehistoric animals. It came into North America from South America, and it resembles other animals that it's not related to. That's called convergent evolution. Because of the way the environment impacts evolution, animals that aren't related can develop similar physical characteristics. In millions of years there may be an animal that looks like an elephant, but isn't...because of whatever vegetation and environmental pressures there will be then.
