Gorillas. Orangutans. Bonobos. Chimpanzees. Humans. Can you name a more iconic Fab Five? This week, Dr. Laura Simone Lewis joins Jonathan for an episode all about our beautiful primate family tree! Listen in to learn how we’re related, what makes each species unique, and why we need to step up conservation efforts for our closest living relatives on the planet.   Dr. Laura Simone Lewis is a postdoctoral fellow at the University of California, Berkeley, and earned her PhD from Harvard in the department of Human Evolutionary Biology. Laura studies how social cognition has evolved in chimpanzees, bonobos, and humans. Besides hanging out with great apes, she loves swimming in the ocean, making pottery, and going on solo travel adventures around the world.   You can follow Dr. Lewis on Twitter @LauraSimoneLew. Here's a link to the chart on human evolutionary pathways. And here's a link to the great ape family tree, with a photo of Jonathan at the center! We have so much more ground to cover with Dr. Lewis, and we’re already planning a follow-up episode about social cognition in chimpanzees and bonobos.
