MARKUS REHM can leap much farther than the length of your family car. He’s a world champion long jumper. But he only has one leg. He wears a device called a prosthesis in place of his missing leg. You’d think that a missing leg would cause problems—especially for an athlete. But the prosthesis Rehm wears is specially designed to propel him forward. It’s a lightweight, curved metal blade. Some call Rehm “Blade Jumper.”
At a 2015 competition for athletes with disabilities, he sailed 27.6 feet (8.4 m). That distance would have beaten the non-disabled gold medalists at the 2012 and 2016 summer Olympics. Rehm wanted to compete in the 2016 summer Olympics. But some thought his blade leg gave him an unfair advantage. And he couldn’t prove that it didn’t.
Researchers have conducted extensive tests on the benefits of blade-shaped legs when it comes to running and jumping. The results are mixed.

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.
