Why are variations in a species needed for natural selection to occur?
What would be selected if organisms did not have differences that lead to better survival and reproduction, or the opposite. That is all natural selection is.
How do you describe Darwin's theory of evolution by natural selection?
The natural production of variation within an animal species and the survival (and by implication breeding) of the fittest variants.
What term can be used to describe evolution by natural selection'?
The term that is often incorrectly used to describe evolution by natural selection is "survival of the fittest."
What is the process called where the environment in which a species lives causes a change to the collective genes of that species?
Natural selection, which is the mechanism for evolution.
What is one effect of natural selection?
Natural selection helps to increase biodiversity and the number of new species.
According to Darwin what determines a species survival or extinction?
Natural selection.
Does the process of natural selection occurs at the species level?
no, at the individual level
Why are variations in a species needed for natural selection to occur?
What would be selected if organisms did not have differences that lead to better survival and reproduction, or the opposite. That is all natural selection is.
How does natural selection influence mimicry?
Quite simply, the better an individual is able to mimic its surroundings, the less likely a predator is to spot it. This gives it a better chance of mating and passing its genes on to the next generation.
Explain how natural selection is at work when a species becomes extinct?
According to science, natural selection chooses the best features for the best survival. When those processes do not occur for some reason, the species does not survive.
How does natural selection enhance or reduce tha variability of a species?
Natural selection 'weeds out' defective genes through successive generations - this both enhances a species chances of survival, and reduces variations in the species genetic make-up.
How is natural variations used in artificial selection?
Natural variation in artificial selection is used because humans choose from among the naturally occurring variation s in species. Natural selection is related to species fitness because Darwin called natural selection survival of the fittest because those that could survive would carry their species on there for being the naturally selected.
How is natural selection used in artificial selection?

Natural selection is related to species fitness because Darwin called natural selection survival of the fittest because those that could survive would carry their species on there for being the naturally selected.
What is the main similarity between the process if artificial selection and natural selection?
The similarity between artificial and natural selection is that they are both weeding out unfavorable traits for favorable traits to be well equipped for survival.
Is evolution a natural selection?
Natural selection explains the process of evolution: evolution by natural selection. It basically means that species with the highest fitness (survival rate) will live, and be selected by nature for the characteristics they possess that make them more apt to survive. Because of natural selection, evolution occurs.
Explain the difference between artificial and natural selection?
Artificial selection is anthropogenic -- humans interfere with nature to determine what traits get passed on, whereas natural selection is when through sexual reproduction the traits passed on are determined by survival of the fittest.
How do you describe Darwin's theory of evolution by natural selection?
The natural production of variation within an animal species and the survival (and by implication breeding) of the fittest variants.
