Which would least likely be a cause of natural selection? adaptation evolution overpopulation variation

The correct answer is Evolution.

Natural selection is a process by which organisms better adapted to their existing environment survive and make more copies of them through reproduction.

Evolution is the result and not a cause of natural selection.This is because natural selection brings change in the heritable characteristics of the population over many generations. This leads to evolution.

On the contrary, if there is variation in a population, the best trait will be selected by the nature and it will propagate. Similarly, if there is large number of population, there are more  chances of some adaptations becoming desirable over others. So adaptation, overpopulation, and variation are the important factors that cause natural selection.

Thus, evolution is the correct answer.

4 Necessary Factors for Natural Selection

4 Necessary Factors for Natural Selection – Overpopulation doesn't necessarily have to occur in order for Natural Selection to happen within a population, but it must be a possibility in order for the environment to put selective pressure on the population and some adaptations to become desirable over others. Which leads to the next necessary…Natural Selection occurs when nature favors an organism. This happens when the strongest and "best fit" to survive are able to reproduce. It is less likely to survive to reproductive age or produce many offspring due to the predator. Thus, natural selection will select and favor the darker mouse which is…Darwin's finches by John Gould.

Natural disasters are a great threat to humanity.

Which leaves overpopulation. Therefore overpopulation would be the least likely cause of natural selection.

Natural selection – Wikipedia – PARIS, 6 May – Nature is declining globally at rates unprecedented in human history – and the rate of species extinctions is accelerating, with grave impacts on people around the "This loss is a direct result of human activity and constitutes a direct threat to human well-being in all regions of the world."But how does natural selection occuring at the species level not affect individuals? Surely any selective advantage of a particular species must occur among particular individuals of that species. For example, if Species A is selected because it is browner than Species B, this will be because…Natural selection explains how evolution occurs. Which of these is not a problem caused by selective breeding? Organisms are more likely to suffer health problems. The antibiotics change over time and become less effective. Mutations in individual bacteria protect them from the antibiotic…
