Green Beard Altruism

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.

abandonware

n. software that is no longer sold or supported by the original publisher / developer, often found as free downloads on the internet because it cannot be obtained elsewhere. Not legal, but often seen as morally acceptable because the company that made it is no longer selling the title, nor releasing it as freeware, therefore abandonware is "keeping the game alive", so to speak.

Doom II is not abandonware because id still sells it, while The Incredible Machine is not sold, therefore is abandonware.

Foot prisons

Socks. Annoying, sweat-causing, non-barefoot enducing, everyday socks.

The first thing I do when I take off my shoes, is rip off the foot prisons I had to wear inside them. That's why I prefer flip flops, even in winter!
