What are the components of natural selection
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.Natural selection involves two components of fitness: reproduction and survival. Under sexual selection, traits that increase reproduction are selected for. In many cases, these traits can reduce survival of the individual, but the overall fitness of the organism is still high due to the enhanced fitness from reproduction.The essence of Darwin's theory is that natural selection will occur if three conditions are met. These conditions, highlighted in bold above, are a struggle for existence, variation and inheritance. These are said to be the necessary and sufficient conditions for natural selection to occur. To say that the three conditions are necessary means ...

Figure 1. Different types of natural selection can impact the distribution of phenotypes within a population. In (a) stabilizing selection, an average phenotype is favored. In (b) directional selection, a change in the environment shifts the spectrum of phenotypes observed.

Darwin’s observations that led to his theory of natural selection are: Overproduction – all species will produce more offspring than will survive to adulthood. Variation – there are variations between members of the same species. Adaptation – traits that increase suitability to a species’ environment will be passed on.The five principles of natural selection are typically described as follows: 1. Most characteristics in the population must be inherited. 2. More offspring must be produced than can survive. 3 ...Evolutionary biology portal Category v t e Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Natural selection states that given these three conditions, a population will accumulate the traits that enable more successful competition. “Origin of the species by means of natural selection” (Darwin, 1859) Darwin used several lines of evidence: 1. Artificial Selection was used as an analogy for natural selection: If humans can breed1.Much of the research on evolution by natural selection done since Darwin relies on a solid and ever-expanding understanding of the process of genetic transmission. 2.Evolution by natural selection is the inevitable consequence of three simple conditions: variation, inheritance, and differential reproductive success.
