Natural selection is the type of selection that can result in a branching evolutionary tree if it goes on long enough. This is because organisms may eventually evolve into a distinct species.
No, natural selection is believed to result in evolution.
Natural selection.
Natural selection.
speciation
No. Evolution is the change in allele frequency over time in a population of organisms. This may be the result of stabilizing selection, but is still evolution.
Natural selection.
increased biodiversity and as a result faster and more effective natural selection and hence evolution.
Evolution through natural selection occurs slowly over millions of years. It has been hypothesized that evolution is the result of positive mutations that occur in a community of organisms that help them survive better. Evolution is essentially descent with modification.
Natural selection is only the result of changing environments, mutation and the variation resulting therein. Natural selection is the process of adaptive change and the main mechanism of evolution that leads to speciation. Natural selection is a process as mutation and variation are grist to the mill of natural selection.
Evolution is the change in populations of organisms over time while speciation is the direct result of natural selection working to select individuals with traits different enough, but beneficial enough, y drive their alleles into greater frequency in popilations so that new species have a chance of arising; either by anagenesis or phylogenesis.
evolution
I believe you are referring to evolution, which occurs as a result of natural selection causing species to change into new species over time.
