Natural selection is defined as a process in nature through which living organisms adapt and change in response to an environmental condition. And organisms that are better suited to their environment tend to survive longer and produce more offspring. ... This variation exists within organisms, and changes occur at random.

What is natural selection and examples?
Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes eaten by snakes and birds.
What do you understand by the term natural selection?
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
What is selection give an example?
The definition of a selection is a person or thing that's been picked or are available to pick. An example of a selection is a cat chosen from a litter of kittens. An example of a selection is a litter of kittens to choose from at the humane society. The act of selecting something.
Which is one of the best example of natural selection?
Tree frogs are the best examples of natural selection.
Natural selection is a natural process in which organisms that are more adapted to their environment successfully reproduce more than those that are not. Snakes and birds, for example, have been known to devour tree frogs.
What is an example of natural selection in humans?
One example of recent natural selection in humans involves the ability to tolerate the sugar, lactose, in milk. In most parts of the world, adults are unable to drink milk because their body switches off the intestinal production of lactase, an enzyme that digests the sugar in the milk, after weaning.
How does natural selection cause evolution examples?
This change in gene structure happens because the environment selects for it; for example it could be a mutation that leads to denser hair and a mutation that leads to more subcutaneous fat which means that in a suddenly sub zero climate these individuals are more likely to survive upto reproductive age because they ...
What do you understand by the term natural selection class 10?
Natural selection means that the organisms with favorable variations will survive because they adapt to the changes in their surroundings while the unfit organisms (who do not adapt to the environment) will be destroyed or eliminated by nature.
What is natural selection class 9?
Natural selection is the process by which organisms having variations, which are better suited to the environment, are more likely to survive and reproduce more efficiently. This ensures inheritance of the beneficial traits to succeeding generations.
What is natural selection Ncert?
Natural selection is an important mechanism of evolution. It states that the organisms that are able to survive and reproduce with the changing environmental conditions are selected by nature while the ones that cannot survive are eliminated.
What do you mean by natural selection class 12?
The process by which plants and animals that can adapt to changes in their environment and are able to survive and reproduce is called natural selection.
What is an example of natural selection at work in a population over time?
An example of natural selection at work - antibiotic resistance. You may have heard about antibiotic resistance. Bacterial infections in humans are commonly treated with antibiotics. However, because of their overuse and misuse, some pathogenic bacteria have become resistant to some of these treatments.
How did Darwin describe natural selection?
In 1859, Charles Darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. He defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
What is necessary for natural selection?
Four (4) conditions for natural selection.
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
What causes natural selection?
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.
