Herbert Spencer was a British philosopher and sociologist who was intellectually active during the Victorian period. He was known for his contributions to evolutionary theory and for applying it outside of biology, to the fields of philosophy, psychology, and within sociology.

Herbert Spencer is famous for his doctrine of social Darwinism, which asserted that the principles of evolution, including natural selection, apply to human societies, social classes, and individuals as well as to biological species developing over geologic time.

Spencer’s basic model of evolution is outlined in Figure For societies, population growth is the basic driving force; the rapidity and diversity of the population growth is what creates different sorts of societies. Society responds to influxes of population by structurally differentiating.

Social Darwinists held that the life of humans in society was a struggle for existence ruled by “survival of the fittest,” a phrase proposed by the British philosopher and scientist Herbert Spencer. …

Answer: The statement that best describes evolution is ” It is the change in heritable traits in living populations over successive generations.”

Which of the following is the best example of gene flow? Wind blows pollen from one population of plants to another and cross-fertilization occurs.

Which best describes the relationship between evolution and natural selection? Natural selection leads to evolution. Natural selection is the same as evolution.

Evolution and “survival of the fittest” are not the same thing. Evolution refers to the cumulative changes in a population or species through time. “Survival of the fittest” is a popular term that refers to the process of natural selection, a mechanism that drives evolutionary change.

Artificial selection has long been used in agriculture to produce animals and crops with desirable traits. The meats sold today are the result of the selective breeding of chickens, cattle, sheep, and pigs. Many fruits and vegetables have been improved or even created through artificial selection.
