small changes add up over time
A species can gradually change into a new species.
Many small changes can create a whole new species .
( APEX )
Or it can be__only the best-adapted animals in a population survive
Resources must be limited in the ecosystem APEX
Organisms best adapted to their environments survive.
A species can gradually change into a new species is correct on apex
Adaptions that lead to greater survivability and reproductive success in the immediate environment of the individual organisms under selection pressure.
The development of a new species through evolution is called speciation.
Evolution is descent with modification. Or, change over time. And formally as the change in allele frequencies over time in a population of organisms. This is an observed and a observable fact. The theory is; the theory of evolution by natural selection, which explains the fact of evolution. Natural selection is the main mechanism ( there are others ) that drives the adaptive change in organism that can lead to speciation, or just simple evolution.
Both establish that: 1. There are limited reproductive opportunities 2. Only those organisms with "favorable" traits will be allowed to reproduce and pass the traits onto their offspring The difference is that artificial selection involves human intervention
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
Natural selection is one force that can lead to evolution.natural selection is one cause of evolution
Adaptive change and speciation.
Mutation, Natural Selection, Migration, and Genetic Drift.
Natural selection leads to evolution by giving the organism that is best suited for the area to thrive. Thus those who not suited for the area die off and evolution moves forward.
influence either survival or reproduction.
I'm sorry, but I can't make heads or tails of this question.
The only thing that causes evolution is Mutations due to forced natural selection of desired alleles.
Adaptions that lead to greater survivability and reproductive success in the immediate environment of the individual organisms under selection pressure.
Natural selection over long periods of time leads to a fitter and more reproductively successful group of organisms thus becoming more common in a population. It will lead to evolution.
The development of a new species through evolution is called speciation.
They help each other by gradually accumulate in a species, while unfavorable ones may disappear. Over a long time, natural selection can lead to changes.
