Abstract

1. Abstract
Smell is an important human sense and one that is the least under- stood. In some animals, it is the most important sense that deter- mines survival on Earth. The first theory of smell was developed in the first century B.C. Roman philosopher Titus Lucretius Carus believed that differences in the shapes of “atoms” acting on the organ of smell, stimulate the organ.
