Natural selection is limited by the ability of the population to produce variation. This in turn is limited by the amount of mutation a lineage can survive. Too many mutations, and the effect becomes detrimental. Too few, and the population may not be able to adapt fast enough to changing circumstances and go extinct.
Without variation in organisms there can be no natural selection.
Physical limits imposed by the fact that natural selection is a tinkerer with what it already has to work with. No wings will sprout from humans even though they might be useful.
in simple words
1- to be powerful enough to compete with other organisms
2-to have the strength to overcome modifications/alterations taking place in environment
Not all of the species evloves, some of them are left as they are, and most of them die out .

What two people disproved evolution?
The Darwinian model of evolution by natural selection has not been disproved.
Compare and contrast natural selection and evolution?
Natural selection is the most powerful driver of evolution and it is the only mechanism of evolution ( genetic drift and gene flow are two other mechanisms ) that leads to adaptive change. Natural selection is the nonrandom survival and reproductive success of of randomly varying organisms. Evolution is the change in allele frequency over time in a population of organisms.
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 two ideas did Darwin use to explain evolution?
natural selection and common descent
The theory of evolution combines which two principles?
selective breeding and genetic resistance
What two factors are responsible for evolution?
Mutation and natural selection.
What two people disproved evolution?
The Darwinian model of evolution by natural selection has not been disproved.
What are the two theories for which Charles Darwin is known A.Evolution and natural selection B.Psychoanalysis and the unconscious C.Evolution and socialism D.Natural selection and psychoanalysis?
A. Evolution and natural selection. Charles Darwin is primarily known for his theories on evolution, which explains how species change over time, and natural selection, which is the process by which advantageous traits become more common in a population.
Can you have evolution without natural selection?
Of course you can. Google genetic drift and gene flow for two evolutionary drivers ( weak drivers ) that have nothing to do with natural selection. Then there is that subsection of natural selection called sexual selection.
Was evolution around before natural selection?
The concept of evolution existed before the theory of natural selection. Evolution as a concept dates back to ancient Greek philosophers, while natural selection was proposed by Charles Darwin in the 19th century as a mechanism to explain how evolution occurs.
What are the contributions of Charles Darwin in the field of evolution?
The theory of evolution by natural selection. Sexual selection. Just to name the two most important contributions of Charles Darwin.

What 2 factors determine the evolution of a species?
Two key factors that determine the evolution of a species are genetic variation and natural selection. Genetic variation provides the raw material for evolutionary change, while natural selection acts on this variation by favoring individuals with traits that increase their chances of survival and reproduction.
Who proposed a theory of evolution by natural selection similar to Darwin?
Alfred Russel Wallace, a contemporary of Charles Darwin, independently proposed a theory of evolution by natural selection that was similar to Darwin's. Wallace's work on natural selection prompted Darwin to publish his own views on the subject. The two scientists jointly presented their work in a paper in 1858.
Do evolutionists believe in natural selection?
" Evolutionists? " Believe in? " Two words/phrases that are ideological in nature and have no place in a scientific discussion. Evolutionary scientists accept the overwhelming and convergent evidence for the theory of evolution by natural selection. This is the best explanation we have for the adaptive changes seen in evolution.
