Assume that you discovered Caenorhabditis elegans that crawl significantly slower than others. How would you determine whether this behavior was due to an injury from the environment or to an inherited trait? A goal of using animal models is to explain the molecular detail of specific behaviors encoded in the human brain. How would you compare the developmental biology experiments on memory and learning using the fruit fly, Drosophila melanogaster, as evidence about the evolution of a human behavior?

Learning and memory

Learning is defined as a relatively permanent and irreversible adaptive change in behavior. It always results from experience. The ability of an organism to store and recall the effects, sensations, and knowledge gained through learning and experience is called memory.
