What else can I help you with?
Which is more likely to be true natural selection or evolution?
Evolution, of course. Evolution can happen without natural selection in some cases; drift, flow. Generally though, natural selection causes evolution and then, by definition, would come first.
What does natural selection cause in a population on a genetic level?
Natural selection causes changes in the frequency of certain genetic traits within a population over time. Traits that confer a survival or reproductive advantage are more likely to be passed on to the next generation, leading to an increase in those beneficial genetic traits in the population.
How does population change as a result of natural selection?
Natural selection is not a thing that acts on populations, it is a tendency for harmful genes to not be passed on (die out) and useful variations to thrive and become common.
How is natural selection and evolution linked?
Natural selection is the process by which certain traits that provide a reproductive advantage become more common in a population over time, leading to evolutionary change. Evolution is the overall change in a population's genetic makeup over successive generations, driven by mechanisms such as natural selection. In essence, natural selection is one of the primary mechanisms through which evolution occurs.
Does natural selection change the individul or the population?
The individual is selected and the population evolves. Keep this straight and you will avoid much confusion in the future.
Which force of evolution makes a population more alike?
Stabilizing selection occurs when the extreme forms of some trait are selected against by natural selection. It is a force of natural selection which causes evolution (definition: change of allele frequency in a population divided by time).
What is true about nature selection?
Natural selection usually causes a species to change gradually
What chararestic within populations causes natural selection to occur?
Variation in traits within a population is what causes natural selection to occur. When individuals in a population exhibit different traits, those that are better suited to their environment are more likely to survive and reproduce, passing on those advantageous traits to the next generation. This process leads to the gradual change of a population over time.

Evolution, of course. Evolution can happen without natural selection in some cases; drift, flow. Generally though, natural selection causes evolution and then, by definition, would come first.
What can the theory of evolution by natural selection explain about a population?
How it can change in response to its enviroment
What process causes behavior to change over generations as a result of reproductive success?
change through natural selection
What are four forces that can change the frequency of genes in a population?
- natural selection - sexual selection - genetic drift - immigration/emagration
What process causes behavior pattern to change over generations as a result of reproductive success?
change through natural selection
What does natural selection cause in a population on a genetic level?
Natural selection causes changes in the frequency of certain genetic traits within a population over time. Traits that confer a survival or reproductive advantage are more likely to be passed on to the next generation, leading to an increase in those beneficial genetic traits in the population.
What must occur for the gene pool within population to change?
natural selection or genetic drift
