A brief treatment of natural selection follows. For full treatment, see evolution: The concept of natural selection. More From Britannica. Mar 29, 2023 · Darwin acknowledges, “Many instincts are so wonderful that their development will probably appear to the reader a difficulty sufficient to overthrow my whole theory.” (p. 228) Darwin states, “He must be a dull man who can examine the exquisite structure of a [honeycomb], so beautifully adapted to its end, without enthusiastic admiration. Darwin’s distinction between good and evil is identical with the distinction made by hedonistic utilitarians. Darwin accepts the greatest-happiness principle as a standard of right and wrong. Hence, an action can be judged as good if it improves the greatest happiness of the greatest number, by either increasing pleasure or decreasing pain.

The crucial break from the concept of constant typological classes or types in biology came with the theory of evolution through natural selection, which was formulated by Charles Darwin and Alfred Wallace in terms of variable populations. Darwin used the expression "descent with modification" rather than "evolution".Darwin's theory of evolution by natural selection is based on four observations about the natural world.

Natural selection, also known as “survival of the fittest,” is the more prolific reproduction of individuals with favorable traits that survive environmental change because of those traits. This leads to evolutionary change, the trait becoming predominant within a population. Darwin's theory of natural selection lacked an adequate account of inheritance, making it logically incomplete. We review the interaction between evolution and genetics, showing how, unlike Mendel, Darwin's lack of a model of the mechanism of inheritance left him unable to interpret his own data that showed Mendelian ratios, even …Darwin’s finches are the emblems of evolution. The birds he saw on the Galapagos Islands during his famous voyage around the world in 1831-1836 changed his thinking about the origin of new species and, eventually, that of the world’s biologists.
