A Tale of Toxins vs. Resistance (2013) watch online HD

"A Tale of Toxins vs. Resistance," lets people in on the dynamic between species that are toxic and their prey, many of which develop such a strong resistance to the poison that they're able to vanquish their predators. But just as some animals become more resistant, the poisonous creatures develop ever more potent poisons through natural selection. In this way, the life-and-death competition between species takes on some of the aspects of the human arms race.
