Crash Course Ecology - Season 1 Episode 1 The History of Life on Earth
0.00 13 minutes With a solid understanding of biology on the small scale under our belts, it's time for the long view - for the next twelve weeks, we'll be learning how the living things that we've studied interact with and influence each other and their environments.
