The Parasite That Makes You King

The video explores the parasitic protozoan Toxoplasma gondii, which can infect various animals, including wolves. While generally harmful, it may benefit wolves by increasing their likelihood of becoming pack leaders. The parasite influences host behavior, making infected animals more prone to risk-taking. A study in Yellowstone showed infected wolves were more likely to disperse and become leaders, despite the risks. Toxoplasma completes its life cycle in cats, with cougars in Yellowstone serving as a primary host. The video also discusses similar effects in other animals, like hyenas and lions.
