In 40 videos, Hank Green teaches you biology! This course is based on the AP Biology curriculum and also covers some introductory anatomy. By the end of this course, you will be able to:
* Recognize the chemicals, molecules, and structures that make up living things * Understand the processes that keep organisms alive and drive cellular reproduction
* Identify evidence of evolution and explain its role in speciation, development, and anatomy
* Describe the characteristics of the different kingdoms and some phyla that make up the taxonomy of living things
* Predict how the interactions between molecules, cells, organisms, and populations contribute to larger systems

Simple Animals: Sponges, Jellies, & Octopuses
Hank introduces us to the "simplest" of the animals, complexity-wise: beginning with sponges (whose very inclusion in the list as "animals" has been called into question because they are so simple) and finishing with the most complex molluscs, octopuses and squid. We differentiate them by the number of tissue layers they have, and by the complexity of those layers.

The Sex Lives of Nonvascular Plants: Alternation of Generations
Hank introduces us to nonvascular plants - liverworts, hornworts & mosses - which have bizarre features, kooky habits, and strange sex lives. Nonvascular plants inherited their reproductive cycle from algae, but have perfected it to the point where it is now used by all plants in one way or another, and has even left traces in our own reproductive systems.

Vascular Plants = Winning!
Hank introduces us to one of the most diverse and important families in the tree of life - the vascular plants. These plants have found tremendous success and the their secret is also their defining trait: conductive tissues that can take food and water from one part of a plant to another part. Though it sounds simple, the ability to move nutrients and water from one part of an organism to another was a evolutionary breakthrough for vascular plants, allowing them to grow exponentially larger, store food for lean times, and develop features that allowed them to spread farther and faster. Plants dominated the earth long before animals even showed up, and even today hold the world records for the largest, most massive, and oldest organisms on the planet.

The Plants & The Bees: Plant Reproduction
Hank gets into the dirty details about vascular plant reproduction: they use the basic alternation of generations developed by nonvascular plants 470 million years ago, but they've tricked it out so that it works a whole lot differently compared to the way it did back in the Ordovician swamps where it got its start. Here's how the vascular plants (ferns, gymnosperms and angiosperms) do it.

Fungi: Death Becomes Them
Death is what fungi are all about. By feasting on the deceased remains of almost all organisms on the planet, converting the organic matter back into soil from which new life will spring, they perform perhaps the most vital function in the global food web. Fungi, which thrive on death, make all life possible.

Ecology - Rules for Living on Earth
Hank introduces us to ecology - the study of the rules of engagement for all of us earthlings - which seeks to explain why the world looks and acts the way it does. The world is crammed with things, both animate and not, that have been interacting with each other all the time, every day, since life on this planet began, and these interactions depend mostly on just two things... Learn what they are as Crash Course Biology takes its final voyage outside the body and into the entire world.

The Traitors
Set in a remote castle in the Scottish Highlands and based on the wildly popular Dutch series of the same name, 5-time Emmy-nominated Alan Cumming plays host to twenty larger-than-life personalities (including reality A-listers and America's best game players) who come together to complete a series of challenges with the objective of earning a cash prize of up to $250,000. The catch? Three of the contestants coined "the traitors" will devise a plan to steal the prize from the other contestants coined "the faithful".
Son of a Critch
Based on the award-winning, best-selling memoir from Mark Critch. This new original comedy is the hilarious and very real story of 11-year-old Mark coming of age in St. John's, Newfoundland in the 80s. It's a heartfelt window into the life of a child – much older inside than his 11 years – using comedy and self-deprecation to win friends and connect with the small collection of people in his limited world.
