What is meant by orthoselection?

Answer 1

Orthoselection :

A primary selective pressure of a directional kind, which results in a self-perpetuating evolutionary trend. Species selection, via the effect hypothesis, has been advanced as an alternative explanation for such trends.

Answer 2

Orthoselection refers to the ability to selectively induce a certain orientation or arrangement in a chemical reaction. It allows for control over the stereochemistry or regiochemistry of a reaction, resulting in the formation of a desired product with specific spatial characteristics. For example, chiral catalysts can be used to promote orthoselective reactions that produce only one enantiomer of a product.
