He came up with this theory as a result of observations from a round-the-world expedition, years of experimentation and his knowledge of geology and fossils. Evolution can be defined as the change in the frequency of a phenotype in a population over many generations. WebMultiple choice questions.

Evolution through natural selection - Natural selection …

WebEvolution is the change of inherited characteristics within a population over time through natural selection, which may result in the formation of a new species. Part of … WebThe statements in Figure 3 below apply to evolution by natural selection, but they are in the wrong order. A: Individuals carrying the mutation survive and reproduce: B: A random variation occurs in and organism during its DNA replication (copying) C: The new allele becomes the predominant one in the population: D: Web1044. 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. Natural selection is one of the ways to account for the millions of species that have lived on Earth. launch ot
