The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits.
Changes that allow an organism to better adapt to its environment will help it survive and have more offspring. The theory is sometimes described as "survival of the fittest," but that can be misleading. Here, "fitness" refers not to an organism's strength or athletic ability, but rather the ability to survive and reproduce.
Mutations can be caused by random errors in DNA replication or repair, or by chemical or radiation damage. Most times, mutations are either harmful or neutral, but in rare instances, a mutation might prove beneficial to the organism. If so, it will become more prevalent in the next generation and spread throughout the population.
In this way, natural selection guides the evolutionary process, preserving and adding up the beneficial mutations and rejecting the bad ones. Mutations are random, but selection for them is not random.

How evolution occurs via natural selection?
Evolution occurs via natural selection when certain traits become more favorable in a population over time. This is typically due to the environment or natural selection pressures in the population. Natural selection works by favoring individuals with traits that are better suited to the environment while those with less favorable traits may die off or be less likely to reproduce. Over time these favored traits become more common while unfavorable traits become less common. This process eventually leads to evolution as the population changes to adapt to its environment. The three main components of natural selection are: Variation: Individuals within a population have different traits Inheritance: Traits are passed from generation to generation Differential Reproduction: Traits that are more favorable are more likely to be passed onNatural selection is an ongoing process as the environment is constantly changing and influencing the traits of the population. It is important to note that natural selection is not a directed process and does not necessarily lead to a specific outcome. The result of natural selection is determined by the environment and the traits that are favored in the population.
What is the main similarity between the process if artificial selection and natural selection?
The similarity between artificial and natural selection is that they are both weeding out unfavorable traits for favorable traits to be well equipped for survival.
What does Darwin's theory of evolution by natural selection predict?
The theory of evolution by natural selection simply summed up. The nonrandom survival and reproductive success of randomly varying organisms.
What happens to unnecessary traits during the process of natural selection?
How does natural selection affect undesirable traits?
What process in which organisims with traits well suited to an environment are more likely to survive and to produce offspring is?
natural selection
What is the process in which traits are chosen to be inherited in evolution?
Natural Selection
What 2 factors determine the evolution of a species?

The only traits that can lead to natural selection and evolution are traits that?
influence either survival or reproduction.
Evolution by natural selection involves what three factors?
there is variation in traits , differential reproduction and last is heredity
When certain traits increase the likelihood of a animal living a long life it is referred to as?
Natural Selection

To Darwin what was central to organic evolution?
To Darwin, the central concept of organic evolution was natural selection. He proposed that individuals with advantageous traits are more likely to survive and reproduce, passing those traits on to their offspring, leading to changes in the characteristics of a population over time.
How does evolution by natural selection differ from lamarcks view of evolution?
Lamark believed that behaviors learned by parents could become inheritable traits.
What are two ideas about evolution that were proposed by scientists in the 18th century?
One was Darwin's theory was the process of evolution by natural selection and the second one was Lyell's theory was that animals can adapt and change their traits to fit the environment.
What is evolution and its relation to natural selection?
Natural selection is the gradual, non-random process by which individuals with a different trait or traits are more reproductively successful than others. This relies on variation existing in the population. Natural selection results in traits becoming more or less common in the population based on the success of those with the trait(s). Natural selection is the main mechanism for evolution. Favourable traits make it more likely for these animals to survive and pass on their genes. This means that over time, more of the population will have these genetics. This can result in species which specialize - and may become a new species. This is how natural selection relates to evolution.
Process by which organisms acquire and pass on novel traits through generations?
evolution or natural selection
Is natural selection responsible for inherited traits?
no, inherited traits are responsible for natural selection
