Origin of Selection Microsphere-like structures almost certainly served as the first protocells. In a population of protocells , Selection could occur. Requirements for selection 1. Population of individuals. Properties of individuals governed based on interactions with the environment.
Individuals differ in efficiency.
Materials, Energy limited. Initially selection was more governed by environment than by heritable characters of the individual. Many molecules are asymmetrical. Such molecules are classified by their abilities to rotate light in particular directions when placed in a fluid medium. Organic macromolecules tend to be L. One strong argument for the single origin of life.
