Which does natural selection affect populations or individuals?
Populations evolve, but individuals are selected. Natural selection affects individual organisms.
What does natural selection only act on?
It acts on populations.
Which of the following is the most powerful evolutionary force in large populations over time?
Only natural selection could be the answer here as natural selection is the main driver of adaptive change leading to evolutionary change and speciation in large populations.
What kind of natural Selection would eliminate one extreme?
Directional selection
Does natural selection require small population size?
No. Natural selection works in all populations. However, new alleles spread more slowly in large populations; the large size has a stabilizing effect. So one should expect large populations to change more slowly than smaller populations.
What will produce adaptive changes in populations?
Natural selection
Is natural selection happening in human populations?
To a very low extent, yes.
How have animal populations changed over time?
Charles Darwin Theory of natural selection
What causes populations to complete?
Compete? The need to be a moron. Complete? The lack of natural selection.
What is natural selection and how does natural selection evolution?
A simplified explanation. Natural selection is the nonrandom survival and reproductive success of randomly varying organisms who by this reproductive success change the allele frequency over time in populations of organisms, which is evolution.
What characteristic within populations cause natural selection to occur?
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
Natural selection causes changes in populations of organisms not individual organisms because?
differential reproductive success caused by genetic variation is necessary for the process of natural selection.
