Biology 2.0

Hi, I’m Dr. Sammy, your friendly neighborhood entomologist and I’ll be your host for Crash Course Biology 2.0! Over the next 50 episodes, we’ll explore the science of life, from the itty bitty cells to the vast global cycles, and discover how species evolve, how genes work, and what happens inside a cell. We’ll also take a look behind the science through the stories of biologists both past and present, and see how biology can help us respond to global challenges like hunger, access to clean water, and climate change. Join me as we explore our place in a big, diverse family tree about four billion years in the making!
