Small Shape-shifters Prepare for Attack.
Want to peer into the world of water fleas? Grab a microscope. These mini-crustaceans, also called daphnia, are approximately the size of several specks of table salt—they range in length from 2 to over 15 grains of salt. They are transparent. In a magnified view, you’ll notice their internal organs are visible from the outside. You may even see their last meal—a green gut means they’ve been feeding on algae. Daphnia have two large antennae they use to swim; the antennae jerk them through the water like jumping fleas. They also have a smaller, less obvious set of antennae, or antennules. This is where an incredible transformation begins.

HUMANS AREN’T THE ONLY PRIMATES THAT USE MEDICATION.
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.

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.
