First, most characteristics of organisms are inherited, or passed from parent to offspring, although how traits were inherited was unknown. Second, more offspring are produced than are able to survive. Natural selection is based on four main principles: variation, overproduction, adaptation and descent with modification. Briefly explain how each of these principles is necessary for natural selection to occur. Variation = natural variation in genetic code, due to mutations. Without this, change would never occur.Herbert Spencer coined the phrase "survival of the fittest".

Darwinism. Charles Darwin in 1868. Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809-1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.Evolution - Natural Selection, Adaptation, Genetics: The central argument of Darwin’s theory of evolution starts with the existence of hereditary variation. Experience with animal and plant breeding had demonstrated to Darwin that variations can be developed that are “useful to man.” So, he reasoned, variations must occur in nature that are favourable or useful in some way to the ...Darwin's concept of natural selection was based on several key observations: Traits are often heritable.

Natural selection changes the relative frequencies of genes in a population of different organisms in a subsequent generation.Natural selection acts on an organism's phenotype, or observable features.Phenotype is often largely a product of genotype (the alleles, or gene versions, the organism carries).When a phenotype produced by certain alleles helps organisms survive and reproduce better than their peers, natural selection can increase the frequency of the helpful alleles from one generation to the next - that ...Any difference between cells or groups of organisms of any type of species caused by genetic differences. Some examples of variation would be: height, able to roll tongue, hair color, eye color, or attached/unattached earlobes.This trait is a result of a mutation from thousands of years ago. The mutation causing the trait was beneficial and heritable, so it spread throughout the human population and many of us today have this trait! There are 4 mechanisms of evolution (how evolution happens): natural selection. mutation. genetic drift, and. Natural Selection - PhET Interactive SimulationsThe anthropic principle, also known as the "observation selection effect", is the hypothesis, first proposed in 1957 by Robert Dicke, that the range of possible observations that could be made about the universe is limited by the fact that observations could happen only in a universe capable of developing intelligent life.
