  • Hi, I'm wildlife ecologist Dr. Rae Wynn-Grant, and welcome to Crash Course: Zoology

  • I've been studying wild animals in their natural habitats for more than 15 years, and

  • I'm just getting started.

  • I discovered my interest in wild animals when I was a kid -- I would sit and watch nature

  • shows for hours on end and wanted to explore the animal kingdom just like the hosts I saw on tv.

  • I later learned that there are entire fields of science dedicated to the study of wild animals!

  • Zoology is the study of those animals and their traits, and how and why they are the way they are.

  • And the scientists who study zoology are zoologists who investigate big questions about how millions

  • of species changed their form and function over time, and how they're related to each

  • other and the rest of the Earth.

  • Others are making medicine from spider venom, learning how to regrow limbs from axolotls,

  • or turning hagfish slime into bulletproof vests.

  • Zoology is a big field and it overlaps with many more.

  • Like ecology, where we study how living things are related to each other and their physical surroundings.

  • These days my work focuses on the way animal behavior can change in environments where

  • humans are present.

  • The work I do helps us better understand wild animals, and also helps us develop the science

  • to save endangered species from going extinct

  • It's super fun, but also very challenging work.

  • I travel around the world and have worked on 6 of the 7 continents studying lowland

  • gorillas in central Africa, grizzly bears in North America, ring tail lemurs in Madagascar,

  • cougars in California, lions in Tanzania, and more. Oh my!

  • And those are just 5 of the 1.5 million animal species we know about and have described in

  • the scientific record.

  • There are millions more out there that are yet to be discovered.

  • And within their incredible diversity, there are many wildly different animals, with surprising

  • adaptations and behaviors.

  • Every single one of them is unique, and at the same time, related.

  • The next 14 episodes will give you a taste of the incredible diversity in the animal

  • kingdom and the surprising ways they've adapted to life on Earth.  

  • We're going to dive deep into how animals are constructed and how they work, what they

  • eat, how they sense their environment, and how they behave.

  • And through it all, we'll show you how evolution has shaped almost everything about them, and

  • how the only way to make sense of the truly wild level of diversity in animals is by examining

  • change over time.

  • We'll spend a whole episode about animals that live inside other animals, and a chunk

  • of another episode about animals that sense electricity and magnetic fields.

  • Just wait until you hear how many beetles there are, or how sea apples evolved, lost,

  • and then evolved their current body shape and lifestyle again

  • It's a wild world out there, hundreds of millions of years in the making, and zoology

  • can give us the tools to make sense of it all.

  • I'll see you next episode!

  • Thanks for watching this episode of Crash Course Zoology which was produced by Complexly

  • in partnership with PBS and NATURE.

  • It is shot on the Team Sandoval Pierce stage at Porchlight Studios in Santa Barbara, California

  • and made with the help of all these nice people.
