Darwin and a scientific contemporary of his, Alfred Russel Wallace, proposed that evolution occurs because of a phenomenon called natural selection. In the theory of natural selection, organisms produce more offspring than are able to survive in their environment.

What is the modern concept of natural selection?
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. ... Through this process of natural selection, favorable traits are transmitted through generations.
What is the modern theory of evolution?
Modern evolutionary theory is based on combining the theory of De Vrie's mutations with Darwin's theory of natural selection leading to descent with modification. ... The Neo Darwin or Modern synthesis is dependent on the concept of mutations creating new information.
What is another way to describe Darwin's theory of natural selection?
More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.
How does modern evolutionary theory relate to Darwin's concepts of variation and natural selection?
The mechanism that Darwin proposed for evolution is natural selection. ... Natural selection causes populations to become adapted, or increasingly well-suited, to their environments over time. Natural selection depends on the environment and requires existing heritable variation in a group.
Who proposed the modern theory?
Modernization theory originated from the ideas of German sociologist Max Weber (1864–1920), which provided the basis for the modernization paradigm developed by Harvard sociologist Talcott Parsons (1902–1979).
What is Charles Darwin's theory of evolution?
Charles Darwin's theory of evolution states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. ... Individuals with characteristics best suited to their environment are more likely to survive, finding food, avoiding predators and resisting disease.
What is Darwin's contribution to modern science explain?
Darwin's greatest contribution to science is that he completed the Copernican Revolution by drawing out for biology the notion of nature as a system of matter in motion governed by natural laws. With Darwin's discovery of natural selection, the origin and adaptations of organisms were brought into the realm of science.
How it is different from Darwinism theory of natural selection?
Charles Darwin popularised the term "natural selection", contrasting it with artificial selection, which in his view is intentional, whereas natural selection is not. ... In other words, natural selection is a key process in the evolution of a population. Natural selection is a cornerstone of modern biology.
What is the Modern Synthesis of Darwin's theory of evolution with refinements from the science of genetics especially regarding the inheritance of traits through DNA?
The Modern Synthesis describes the fusion (merger) of Mendelian genetics with Darwinian evolution that resulted in a unified theory of evolution. It is sometimes referred to as the Neo-Darwinian theory. The Modern Synthesis was developed by a number of now-legendary evolutionary biologists in the 1930s and 1940s.
Which component of the modern theory of evolution explains where new variation comes from?
Mutations are the source of new variation. Natural selection itself does not create new traits; it only changes the proportion of variation that is already present in the population. The repeated two-step interaction of these processes is what leads to the evolution of novel adaptive features.
How does modern evolutionary theory contribute to our view of social change?
According to evolutionary theory, society moves in specific directions. Therefore, early social evolutionists saw society as progressing to higher and higher levels. As a result, they concluded that their own cultural attitudes and behaviors were more advanced than those of earlier societies.
What is modern synthetic theory?
The modern synthetic theory of evolution describes the evolution in terms of genetic variations in a population that leads to the formation of a new species. It explains the contribution of factors such as genetic variations, reproductive and geographical isolation, and natural selection.
How does natural selection lead to evolution?
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
How did Darwin discover natural selection?
A visit to the Galapagos Islands in 1835 helped Darwin formulate his ideas on natural selection. He found several species of finch adapted to different environmental niches. The finches also differed in beak shape, food source, and how food was captured.
How does Darwin's theory affect us today?
Darwinism allowed us to gain a better understanding of our world, which in turn allowed us to change the way that we think. ... By being able to apply this to other animals, it changed the way that people thought about life on earth and opened new doors for science in the future.
How can Darwin's evolutionary theory influence agriculture in modern times?
Can agriculture learn any lessons from Charles Darwin? ... Denison says Darwin's best argument for the power of natural selection was borrowed from agriculture, specifically the success of plant and animal breeders in improving crops and livestock simply by selecting which plants and animals get to reproduce.
