Natural Selection has a role in the changing population because the stongest genes stay and the weakest genes become extint (because the person has died) and so in conclusion that means that more and more people with the strongest genes will reproduce and the off spring will have the stronger gene. Meaning the population may not change in appearance but will change inside their bodies and become stronger.
What else can I help you with?
What is the role of the natural selection in evolution and what role does it play in environmental science?
Natural selection is the changing of organisms gradually over time. Natural selection and evolution are parts of environmental science due to them being the studies of organisms.

Which form of natural selection is most likely to play a role in speciation?
Reproductive isolation through sexual selection is often an important factor in speciation. This type of natural selection can lead to the evolution of reproductive barriers that prevent individuals from different populations from successfully interbreeding, ultimately resulting in the formation of distinct species.
What drives the process of evolution?
Mutation, genetic drift and gene flow can all drive evolution to a degree and the last two, drift and flow, are especially powerful in small populations. But, the driver of adaptive change in all populations of organisms is natural selection.
What role does the environment play on natural selection?
Nature plays no direct role in artificial selection. That is the difference between artificial selection and natural selection. Nature does play some indirect roles in artificial selection. One indirect role is in providing the organisms with which one beings the artificial selection. Another is in influencing the choices of the organism performing the artificial selection.
What provides the direction evolution takes?
Really only natural selection can provide an adaptive direction to evolution. Both gene flow and genetic drift can change allele sequences over time in populations but that is not enough to bring about speciation in those populations. Only natural selection gives you the adaptive change and directional selection that creates new species.
Does natural selection operate on today's society?
Modern human society is influenced by factors beyond natural selection, such as technology and medicine. While genetic differences can still have impacts on survival and reproduction, natural selection plays a diminished role in shaping human populations compared to its historical significance. Social and cultural factors now play a larger role in determining individual success and reproductive outcomes.
What role does natural selection play in microevolution?
First, I should mention that 'micro-evolution' is not a process in itself. Rather, it is a perspective on the effects of evolution. 'Micro-evolution' is those effects seen from close-up; by 'zooming out' one sees those same results in a wider scope called 'macro-evolution'. All evolution is driven by genetic variation and natural selection. Natural selection drives evolution by filtering out some variations while promoting others, thereby directing the slow change of morphology and behaviour of populations.
What is the role of recombinations in evolution?
Recombinations play a key role in evolution by shuffling genetic material from two parents to create genetic diversity in offspring. This genetic diversity allows populations to adapt to changing environments and increases the chances of beneficial traits being passed on to future generations. Recombination helps drive natural selection by providing a wider pool of genetic variation for organisms to evolve and survive.
Is NOT a component of the theory of evolution by natural selection?
Acquired traits. The theory of evolution by natural selection focuses on inherited traits that provide a reproductive advantage. Acquired traits, which are not genetically determined, do not play a direct role in this process.
What role do alleles play in natural selection?
Genes are the medium by which inherited traits are passed on to offspring. It is inherited traits, and thus genes, that receive positive or negative selection.
Why and how is over production important to natural selection?
Overproduction leads to more animals competing for the same amount of food, etc. This is where natural selection comes into play and those who are better adapted are more likely to survive and reproduce. Overtime this leads those with the beneficial traits to survive and the others to gradually die off...
