WebMechanisms of Evolution. Populations evolve, but individual organisms do not. A population is an interbreeding group of individuals of one species in a given geographic area at the same time. A population evolves because the population contains the collection of genes called the gene pool. As changes in the gene pool occur, a population evolves. WebOne of the steps that often generates difficulties is cell isolation and separation. Depending on the final goal of the research, various techniques can be used to make this process more efficient and quick. One of the most used and compatible methods to isolate single cells is flow cytometry with Fluorescence-Activated Cell Sorting (FACS).
