CORE DEFINITION

Any investment (time, energy, risk) made by parents for the survival and reproductive success of their offspring, at the cost of the parents' ability to invest in other offspring.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

The biological basis of sunk costs. Because too much has been invested in a child, it is impossible to let go. This is also the source of brand loyalty—the more time and data users invest in a product (parental investment), the more indispensable it becomes.

Parental investment in resources/care affects offspring survival; heavier investment leads to fewer but higher-quality offspring, shaping reproductive strategies.

Exaptation

A trait originally evolved or invented for one function is later co-opted to serve a completely new function. Gould and Vrba coined the term in 1982 to replace the teleological "pre-adaptation".

Semelparity

Semelparity and iteroparity are two reproductive strategies available to living organisms. A species is semelparous if it is characterized by a single reproductive episode before death, and iteroparous if it is characterized by multiple reproductive cycles.

The Anna Karenina Principle

For tasks requiring several necessary conditions jointly, failure of any one may prevent success; this does not make all successful cases identical.
