Science in Motion: Genetics of Self-Sacrifice

The video explores whether animals can make sacrifices or cooperate without direct benefits, focusing on a lizard species with three genetic variations. Each variation exhibits different behaviors: orange throats are aggressive, yellow throats are sneaky, and blue throats cooperate in buddy systems. The blue-throated lizards' cooperation may lead to more offspring of their genetic type, highlighting a form of altruism in nature.

In what way does evolution prioritize the survival of species according to the text?
