Greenbeard altruism is a fascinating concept in evolutionary biology that attempts to explain the evolution of altruistic behavior. It proposes that a single gene (or a set of tightly linked genes) can be responsible for three distinct traits: a noticeable signal or "tag" (like a green beard), recognition of that signal in others, and altruistic behavior directed towards those with the same signal. This allows individuals to selectively cooperate with others who share the same gene, even if they are not related. 1 While the "green beard" example is hypothetical, there are real-world examples of this phenomenon in various organisms, highlighting the potential for cooperation to arise through mechanisms beyond kin selection.
Green beard altruism, while theoretically possible, is rarely observed in nature due to the complex requirements of a single gene controlling the signal, recognition, and altruistic behavior.

Get the green milkmug. Basically kid in front of the green screen that reacts to short. But the true is they hide in the corner of the screen, and stealing the content, sometimes giving no credit to the original creator. Like these Green screen kids sucks, they don't give a fuck to the lazy content they made. Somehow, they got a lot of views like how tf?
