NEET BIOLOGY

Detailed explanation-1: -Overproduction alone will have no evolutionary consequences if all individuals are identical. Differences among organisms are not relevant unless they can be inherited. Genetic variation by itself will not result in natural selection unless it exerts some impact on organism survival and reproduction.

Detailed explanation-2: -Overproduction of offspring’s leads to competition among individuals in which the fittest and adapted individual survives. Overproduction is also known as a driving force in natural selection as it can lead to adaptation and variation in a species.

Detailed explanation-3: -Whilst researching his theory of evolution, Charles Darwin observed that many animals overproduce offspring, which means they have lots of babies, more than the environment can support. By producing lots of offspring, it is more likely that some of them will survive to adulthood and then breed themselves.

Detailed explanation-4: -What You Need To Know. You need to know the conditions required for natural selection to occur. These include: overproduction of offspring, inherited variation, and the struggle to survive, which result in differential reproductive success.

Detailed explanation-5: -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.
