Crested iguanas were discovered on Fiji in 1979, and since then we've learned a lot about their behaviour, including their strange mating rituals. But how exactly did they end up on such a remote island in the first place?
Epidote might just look like a pretty little crystal, but it has a secret. thanks to the high-pressure circumstances where it forms, we can use it to help us uncover the origins of life on our planet, and maybe even find signs of life on Mars.
Your DNA contains all the instructions your body needs to function. In this episode of Crash Course Biology, we’ll figure out what this giant instruction manual looks like and how this three-billion-letter code gets copied into your trillions of cells through DNA replication.
Ever wonder why we aren’t exact clones of our parents, or why siblings aren’t exactly alike? The reason traces back to meiosis. In this episode of Crash Course Biology, we’ll discover how egg and sperm cells get made and learn why you’re a totally unique remix of your parents’ DNA.
Biologist Kathleen McAuliffe dives into new research that suggests certain bacteria in your gut can influence major parts of who you are, from your personality to life-changing neurological disorders.
Cells need energy to power the chemical reactions that keep their microscopic cities running, and most of that energy comes from a chemical called ATP.
The world relies on manufacturing, and manufacturing relies on heat — a massive contributor to global carbon emissions, responsible for a quarter of the world's fossil fuel use.
Humans may have been around for a long time, but life has existed for way longer. In this episode of Crash Course Biology, we’ll journey through deep time to uncover the history of life on Earth.
We've long known that animal pollination is an important way plants reproduce on land, but we're only JUST finding out animals also pollinate plants underwater.
How come sharks get to have endlessly regrowing teeth when humans only get one set our entire lives? And how come some other mammals get to cheat the system? From elephants to baboons, we'll learn why teeth don't grow back.
