CORE DEFINITION

An extinct giant deer whose antlers could reach 3.6 meters in width. The overdeveloped antlers may have been the result of sexual selection, ultimately leading to extinction due to the inability to support their weight.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

The danger of over-specialization. When a trait is over-optimized (e.g., a company over-pursuing scale, an individual over-pursuing a certain skill), it can become a burden to survival. Moderation and balance are more important than extreme optimization.

anchor

Anchor fast decisions

The Irish elk (giant deer) had extremely exaggerated antlers due to male competition, which, while beneficial for mating, increased survival costs. It is seen as an example of 'runaway sexual selection' and the danger of over-specialization.
