Just look at this photo. Can you think of anything more adorable than a baby orangutan? It’s no wonder that they’re one of the most popular zoo animals! But it’s not just their cute appearance that draws us to these sweet creatures. We’re also fascinated by how much like us they are!
Orangutans are one of our closest cousins. Humans and orangutans share more than 97% of their DNA. Yes, they spend most of their time swinging gracefully from trees with their uniquely long arms — while we plod along flat-footed down on the ground. But our similarities are readily apparent in many other ways, from our facial features to the way we hold objects with our shared secret evolutionary weapon: opposable thumbs.
