The Earth is really, really old. It’s so old that it’s tough to imagine how old it is. The best we can do is come up with a metaphor that compares it to things we deal with in everyday life. Dinosaurs went extinct around 66 million years ago. That’s a long time ago, about 1,000 times further back than humans have been around. People that looked like us first turned up about 300,000 years ago. But here’s where it gets wild: the Earth itself formed about 4.54 billion years ago. If you could time travel 66 million years in a single step, you’d have to take about 70 steps to get to the first days of the planet! By the time dinosaurs went extinct, almost 99 percent of Earth’s history had already happened.

THE LEFT OVERS
A lot has happened for modern humans to get to this point. We lost most of our hair, learned how to make tools, established civilizations, sent a person to the Moon, and invented artificial intelligence. Whew! With all of these changes, our bodies have changed, too. It’s only taken us about six million years.
SO, WHAT IS A PRIMATE?
What do you have in common with the aye-aye, sifaka, siamang, and potto? If you said your collarbone, you re probably a primatologist—a person who studies primates. If you’re not, read on.
