Exposure of a population to a toxin that kills a high percentage of the population selectively eliminates those individuals most susceptible to the toxin. This leaves the most resistant individuals to reproduce individuals that are also resistant. After many generations of this selection the whole population is resistant.
his development in science is that he created the natural selection
Adaptation does not allow for natural selection: natural selection causes adaptation.
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
The development of a new species through evolution is called speciation.
They are the selective agent in natural selection ;)
An example of microevolution is the development of antibiotic resistance in bacteria due to natural selection. Over time, bacteria that are resistant to antibiotics survive and reproduce, leading to a population of bacteria that is predominantly resistant to that antibiotic.
Natural selection is the mechanism primarily responsible for the development of today's biodiversity.
Bacteria is the answer
The process of natural selection results in populations of bacteria that are not harmed by antibiotics because bacteria that are born with mutations that make them immune to antibiotics will be the ones to survive and reproduce.
Natural development and selection.
The development of antibiotic resistance in bacteria is a result of genetic variation that was favored by natural selection. Bacteria that had a mutation making them resistant to antibiotics were able to survive and reproduce, passing on this trait to future generations. Over time, this led to the prevalence of antibiotic-resistant strains in bacterial populations.
No, all life evolves. Bacteria evolve, viruses evolve, protists evolve, plants evolve, fungi evolve and animals evolve. Evolution is driven by Natural Selection. So, no. The evolution of all life on Earth is driven by Natural Selection: all bacteria, plants, animals, mammals, fish, insects, biochemical pathways, behaviours et cetera evolve by Natural Selection.
mutations that allow the bacteria to survive the antibiotic's effects, leading to the selection of resistant bacterial strains. These resistant strains can then replicate and spread, making subsequent infections harder to treat. Additionally, the overuse and misuse of antibiotics can contribute to the development of antibiotic resistance.

Evolution is the process by which living organisms change and adapt over time through natural selection. An example of evolution is the development of antibiotic resistance in bacteria. When exposed to antibiotics, only the bacteria with genetic mutations that make them resistant survive and reproduce, leading to a population of bacteria that is mostly resistant to the antibiotic.
