If an organism is already well suited to its environment, there is no need for it to change or 'adapt'.
This can be seen in sharks and crocidiles, they have changed very little over thousands of years and are the top predators in their environment, as such they have not changed as they have not had to.

Why is genetic variation important for natural selection to drive evolution?
Genetic variation is important for natural selection to drive evolution because it provides the raw material for natural selection to act upon. Without genetic variation, there would be no diversity in traits for natural selection to favor or eliminate, and evolution would not be possible.
Which is more likely to be true natural selection or evolution?
Evolution, of course. Evolution can happen without natural selection in some cases; drift, flow. Generally though, natural selection causes evolution and then, by definition, would come first.
Evolution by natural selection works best on populatin having no variation?
Evolution by natural selection actually relies on variation within a population. Without variation, there would be no genetic differences for natural selection to act upon, leading to no evolution. Variation provides the raw material for natural selection to work with, allowing beneficial traits to be favored and passed on to future generations.
Why is it the Darwin theory natural selection is nice?
Nice? The theory of evolution by natural selection is the best and best supported explanation for the fact of evolution we have, but it just is and a word such as " nice " would not always fit theory. Google Ichneumon wasp to see that natural selection is not always " nice. "
Would evolution stop if there were no natural selection?
No, but adaptive change would be difficult. Remember, evolution is the change in allele frequency over time in a population of organisms. Mutation, genetic drift, genetic flow and other processes would continue without natural selection.
Why should people believe in evolution?
People should not " believe in " evolution but accept that evolution, the change in allele frequency over time in a population of organisms, is fact. The also need to consider the theory of evolution by natural selection, which explains much about evolution, as one of the most well supported explanatory theories in science. Then they would, if they are intellectually honest, come to accept not only the fact of evolution but the theory of evolution by natural selection. " Believe in " is a term one uses when one can provide no supporting evidence for one's concepts and this does not include evolution and the theory of evolution by natural selection.

How would you use evolution natural selection adaptation and fitness in a sentence?
An important mechanism in evolution is natural selection, which allows populations to develop adaptations to changing circumstances based on the fitness landscape of the environment. Nah, still doesn't work. I'm no good at long sentences.
What term can be used to describe natural selection?
Survival of the fittest
Who was the English scientist who proposed the theory known as natural selection?
Charles Darwin's theory of evolution included the natural selection as a means that determined which species would survive and which did not. It remains an open question in the present time.
Which 2 scientists independently proposed natural selection as the mechanism of evolution?
That would be Charles Robert Darwin and Alfred Russel Wallace.
That evolution by natural selection is occurring in this cactus population?
To determine if evolution by natural selection is occurring in a cactus population, you would need to observe changes in the heritable traits of the cacti over time, caused by differences in survival and reproduction. This would indicate that certain traits are being favored, leading to a shift in the genetic makeup of the population.
Which of the five factors that can lead to evolution would operate on a change in body color that enabled animals to better hide from predators?
natural selection :")
