The core of Darwin's theory is natural selection, a process that occurs over successive generations and is defined as the differential reproduction of genotypes. Natural selection requires heritable variation in a given trait, and differential survival and reproduction associated with possession of that trait.Charles Darwin. Charles Darwin - Evolution, Natural Selection, Species: England became quieter and more prosperous in the 1850s, and by mid-decade the professionals were taking over, instituting exams and establishing a meritocracy.

(4 points) The only way to eliminate harmful mutations is through natural selection. Mutations occur at random; natural selection can preserve and distribute beneficial mutations. Natural selection creates beneficial mutations. Natural selection is a random process. VISTA. Natural selection is a simple mechanism that causes populations of living things to change over time. In fact, it is so simple that it can be broken down into five basic steps, abbreviated here as VISTA: Variation, Inheritance, Selection, Time and Adaptation. The four key points of Darwin’s Theory of Evolution are: individuals of a species are not identical; traits are passed from generation to generation; more offspring are born than can survive; and only the survivors of the competition for resources will reproduce.We'll begin by looking at Darwin's own words, in chapters 3 and 4 of the Origin (chapter 3 on "struggle for existence", and chapter 4 on "natural selection".) ...overproduction. more offspring can be produced than can survive to maturity. genetic variation. within a population, individuals have different traits and the traits can be inherited. struggle to survive. compete for food and shelter.
