Overproduction, variation, selection, and adaptation
Generally and simply, mutation, genetic variation and natural selection.
No. Intelligent Design is not a viable theory since it does not explain all of the steps nor provide any evidence to substantiate its claims. As a result, the Theory of Evolution remains unchallenged by it.
1. Reproduction Information (DNA is used for life on Earth) is accurately replicated. 2. Variation Changes in parts of the information caused by mutation or recombination. 3. Selection Individuals with changes that give rise to increased reproductive success, will tend to have more offspring. This will spread that advantageous change through the population. Changes that reduce reproductive success will lead to less offspring and so are "weeded out" by selection.

Overproduction, variation, selection, and adaptation
Generally and simply, mutation, genetic variation and natural selection.
There are really no steps in natural selection - just conditions required for it to occur.
The four stages are: Overproduction, Genetic Variation, Struggle to Survive, and Successful Reproduction
overproduction: to many offspring and 3 others
Why do different organisms live in different places Why do different regions have different organisms
Artificial selection.Artificial selection is the selection, by humans, of which individual plants or animals to breed from. In this way desirable characteristics, such as increased yield or disease resistance, can be preserved or improved.Charles Darwin used artificial seletion as a model for how evolution could take place in nature, where competiton between individuals replaced the selective action of humans. He called the natural process 'natural selection'.See http://evolution.berkeley.edu/evosite/evo101/IIIE4Evochange.shtmlfor an excellent account.

Charles Darwin's theory of natural selection applies to organisms who adapt to their environment better than others and survive to pass on their traits to offspring. Due to variation in their genes, may be caused by mutation but rarely so, organisms are able to adapt to their environment. If they don't adapt well they die. If they adapt to their environment it means that they have fought for their survival and are now able to pass on their variations to their offspring and make them stronger. Often as a result a new species is formed due to the accumulated differences.There are three types of natural selection: Directional, disruptive, and stabilizing selection. In directional selection only one extreme genotype is favored to pass on. Meaning the environment chooses one genotype to pass on. An extreme genotype for example would be either SS or ss for sickle cell, either the genotype for sickle cell is passed on or the non-sickle cell genotype is passed on. In disruptive selection, a disruption separates similar organisms causing the favoring of two extreme genotypes. For example both SS and ss are favored to pass on. In stabilizing selection only the middle genotype is favored meaning Ss which is carrier of sickle cell.Natural selection is when the environment determines which alleles enable organisms to survive.The theory of natural selection states that traits in a species become more or less prevalent depending on environmental pressures that select either for or against such traits.Individuals that have traits that better suit their environment are more likely to survive.Darwin broke down the process into 4 steps:1. individuals that make up a population vary in their traits2. some of these trait differences are heritable3. in each generation, many more offspring are produced than can survive. Only some individuals survive. Of these, some will produce more offspring than others4. Individuals with certain heritable traits are more likely to survive and reproduce.Natural Selection occurs when individuals with certain traits produce more offspring than do individuals with certain traits produce more offspring that do individuals without those traits.when organism adapt to the environment they will be likely to survive and produce healthy offspring.
The selection process includes submitting an application, validation of the forms, pre-selection of the candidates, interviews, verifying the documents, final section and contract. Only applicants that meet the stated requirements can be chosen.
