### Key Terms in Biology and Psychology #### Altruism Altruism refers to the selfless concern for the well-being of others, often leading to behavior that is beneficial to others at a cost to oneself. #### Circadian Rhythm A circadian rhythm is a natural, internal process that regulates the sleep-wake cycle and repeats roughly every 24 hours. It can influence sleep patterns, hormone release, eating habits, and other bodily functions. #### Neanderthal Neanderthals are an extinct species or subspecies of archaic humans who lived in Eurasia until approximately 40,000 years ago. They are closely related to modern humans, sharing a common ancestor. #### Pheromone Pheromones are chemicals produced and released into the environment by an animal (often an insect), affecting the behavior or physiology of others of its species. They are often used for communication, marking territory, mating, and signaling danger.
