What is selectionalism?

Answer 1

Hyper-selectionism, in the philosophy of Biology, refers to people who attribute all (or nearly all) evolutionary change to natural selection, and ignore, disregard or minimize the significance of so-called "random" sorting mechanisms such as genetic drift.

The term is usually applied as a criticism of someone else's work. Nobody refers to themselves as a hyper-selectionist.

It's not a disease, so I think you might have asked in the wrong forum.

Answer 2

Selectionalism is a theory in linguistics that focuses on how words are selected based on their meaning and grammatical properties in sentence construction. It examines how words in a sentence are chosen based on the required semantic relationships with other words in order to create a coherent and meaningful expression.
