How natural selection favor evolution of drug-resistant pathogens?
Natural selection favors the evolution of drug-resistant pathogens because when a population of pathogens is exposed to antibiotics, those that have genetic variations allowing them to survive and reproduce will pass on these resistance traits to future generations. Over time, this can lead to the emergence of drug-resistant strains as the surviving pathogens multiply.
Why is it important for physicians to have a clear understanding of evolution by natural selection?
Physicians prescribe drugs to the patients.But the pathogens have the propensity to evolve and become "super bugs"(so called because they are drug resistant).This could lead to a bad condition of the disease or might develop some rare form of disease.The common cause of the development of drug resistance is inappropriate dosage of drugs.In that case these drugs act as natural selection agents and could not kill the entire population of pathogens this could lead to the increase in frequency of those resistant forms of pathogens.So if a physican has a clear understanding of evolution by natural selection he will not be careless about the dosage of drugs
Is natural selection a cause of evolution?
No, natural selection is believed to result in evolution.
Can natural selection exist with out evolution?
Perhaps not, but evolution can exist without natural selection.
What is another word for Darwin's theory of natural selection?
Evolution by natural selection.
Darwin's theory of evolution by natural?
Evolution by natural selection.
Which type of natural selection prevents evolution?
Natural selection directs evolution; it cannot stop or prevent it.
How are evolution and natural selection related?
Natural selection is one of the mechanisms that shapes adaptation and enables evolution.
Is evolution a natural selection?
Natural selection explains the process of evolution: evolution by natural selection. It basically means that species with the highest fitness (survival rate) will live, and be selected by nature for the characteristics they possess that make them more apt to survive. Because of natural selection, evolution occurs.
In evolution survival of the fittest refers to?
In evolution, natural selection is often called survival of the fittest.
What principles is not part of Darwin's original theory of evolution by natural selection?
Random processes are not part of the theory of evolution by natural selection.
What was Charles Darwin's contribution to science?
his development in science is that he created the natural selection
