Biology of Aging
A basic assumption that underlies a great deal of this research is that the use of models for research on human aging is valid and informative. Models for research include a wide variety of organisms, including yeast, worms, rodents, and nonhuman primates. Many genes are common to the genomes of all of these organisms. Humans share genes even with yeasts. Thus it is assumed that phenomena observed in these model organisms provide relevant information about how aging occurs in the human species.
