Final answer:
Karl Von Frisch is known for discovering the unique communication method of honeybees, known as the waggle dance, which earned him a Nobel Prize in Physiology or Medicine in 1973.
Step-by-step explanation:
Karl Von Frisch is renowned for his groundbreaking work in the field of ethology, specifically for deciphering the communication system of honeybees through their waggle dance. His work expanded the understanding of animal behavior and was instrumental in explaining how bees communicate the location of food sources to their hive mates. His profound contributions to biology earned him the Nobel Prize in Physiology or Medicine in 1973, sharing it with Konrad Lorenz and Nikolaas Tinbergen, for their collective works concerning organization and elicitation of individual and social behavior patterns in animals.
