This video provides an overview of the types of genes that, when mutated, can lead to the development of cancer.

This animation shows how disrupting cellular processes in the intestines can lead to colon cancer.

This film describes natural selection and adaptation in populations of rock pocket mice living in the American Southwest.

This animation shows how a mutation that allows adult humans to digest milk can be lost or spread under different circumstances.

This video explores the evolution of a stickleback fish population over tens of thousands of years, based on fossil data.

This animation shows how quickly an advantageous mutation can spread through a mouse population over multiple generations.

This animation shows how a tumor forms, recruits blood vessels, and enters metastasis.

This video provides a demonstration of differences between sexual reproduction, which involves recombination through meiosis, and asexual reproduction, which does not.

This animation shows how meiosis, the form of cell division unique to egg and sperm production, can give rise to sperm that carry either an X or a Y chromosome.

This animation shows how recombination occurs between the X and Y chromosomes, then within the Y chromosome itself.
