Describe the role that Charles Darwin played in the study of human development

British naturalist Charles Darwin observed the infinite variation among plant and animal species. He also saw that within a species, no two individuals are exactly alike. From these observations, he constructed his famous theory of evolution. The theory emphasized two related principles: natural selection and survival of the fittest. Darwin explained that certain species survive in particular environments because they have characteristics that fit with, or are adapted to, their surroundings. Other species die off because they are less well-suited to their environments. Individuals within a species who best meet the environment's survival requirements live long enough to reproduce and pass their more beneficial characteristics to future generations. Darwin's emphasis on the adaptive value of physical characteristics and behavior found its way into important developmental theories.
During his explorations, Darwin discovered that early prenatal growth is strikingly similar in many species. Other scientists concluded from Darwin's observations that the development of the human child follows the same general plan as the evolution of the human species. Although this belief eventually proved inaccurate, efforts to chart parallels between child growth and human evolution prompted researchers to make careful observations of all aspects of children's behavior. Out of these first attempts to document an idea about development, scientific child study was born.
