Slide 4: Family as an evolving idea
Yet concern with the individual’s emotional needs is a relatively recent historical development. From an evolutionary perspective, families are necessary first and foremost for survival. Of all mammals, humans take the longest to develop into adults—and live the longest as adults. Consequently, throughout human history a family structure, in one form or another, has existed to nurture and protect the young and to tend to and care for the aged. Above, Charles Knight’s “Neanderthal Flint Workers” (1926) which shows a family at the Le Moustier cave in southern France hangs in the American Museum of Natural History in New York.
