Natural selection favors a trait by increasing its frequency in a population. Natural selection is differential reproductive success. If one variant of a trait enables an organism to have and raise more offspring successfully than other variants in a particualr environment, then it will become more common in the population.

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.
What scientist proposed that all organisms evolved toward perfection and complexity?
Jean-Baptiste Lamarck proposed the theory of evolution known as Lamarckism, which suggested that organisms evolve toward perfection and complexity through the inheritance of acquired traits. This theory has been largely discredited in favor of Charles Darwin's theory of natural selection.
What factors support evolution-?
As we currently understand it, evolution happens if: - There are populations of organisms reproducing with variation - Those variations are inherited by offspring - More offspring is produced than can comfortably subsist in the habitat - Offspring therefore compete with one another for resources and mating opportunities - Variant inherited traits affect their ability to compete.
What is the role of natural selection in convergent evolution?
If it is easier or more likely that an organsim is going to survive and reproduce if that organism works together with another or takes advantage of a certain opportunity, natural selection will favor the organisms that are more suited to maintaining their realtionship with the other organism.
What happens when previous adaptations are no longer suitable for changes in the environment?
Organisms may struggle to survive and reproduce, leading to decreased population fitness. Over time, natural selection may favor individuals with genetic variations more suited to the new environment, promoting adaptation and evolution. If the changes are too rapid or extreme, it could potentially lead to extinction.
When natural selection favor the intermediate version of a characteristic it is called?
stabilizing selection
How natural selection favor evolution of drug resistant pathogens?
because he died from.....
How does selection favor calling How does selection favor not calling?
Not
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.
Natural selection would favor which of the these rabbits in Antarctica?
It would favor white because then it could camouflage and hide from predators and would be most likely to survive
How can natural selection favor different phenotypes at different times?
Natural selection is something that happens over time and is somewhat dependent on the conditions of climate and environmental changes. There are times when natural selection can favor different phenotypes, if and when the culture starts to seek out others with certain traits and characteristics to breed.
Forensic pathologist use evidence to find what evidence in favor of evolution and natural selection?
direct evidence is the observation as it occurs
Natural selection can favor traits that make an animal more vulnerable to predators if those animals?
Leave more offspring
How does natural selection favor timid mice over bold mice?
Timid mice are less likely to be caught by a predator.
What were Darwin's best arguments in favor of his theory of evolution what were the most serious objections to it?
Darwin's best argument in favor of the theory of evolution was natural selection. The most serious objections came from religion.
What is the role of the environment in the selection of the future selection that will prevail in a given area?
The environment plays a key role in natural selection by exerting pressures that favor certain traits over others. Organisms with advantageous traits for a specific environment are more likely to survive and reproduce, passing on those traits to future generations. Over time, this process leads to the selection of traits that are well-suited to the specific environmental conditions of a given area.
What scientist proposed that all organisms evolved toward perfection and complexity?
Jean-Baptiste Lamarck proposed the theory of evolution known as Lamarckism, which suggested that organisms evolve toward perfection and complexity through the inheritance of acquired traits. This theory has been largely discredited in favor of Charles Darwin's theory of natural selection.
