Natural selection is the process that result in the adaptation of an organism to environment by means of selectively reproducing changes in its genotype, or genetic constitution. It is the a key mechanism of evolution. Charles Darwin popularised the term "natural selection" contrasting it with artificial selection, which is intentional, whereas natural selection is not.
To make it simple, let's have a group of beetle composing of green and some are brown as an example. here, there is a variation in traits. Since the environment could not support continuous population growth, not all species can reproduce to their full potential. Green beetles can easily be eaten by other species like birds compared to brown beetles. The surviving brown beetles will then generate brown offsprings because their trait has a genetic basis. Since more brown beetles survive and becomes more common in the population, the process continues until all individuals will eventually be brown. so basically, if you have variation, differential reproduction, and heredity, you will have evolution by natural selection as an outcome.
I would have to say <span>This is an example of incomplete dominance but i'm not sure if correct. </span>
One such example of flowers which smells like rotten meat are- Carrion flowers or corpse flowers. The pollinators for these flowers are mostly <u>beetles and flies</u>. The mode of pollen transfer is by trapping these insects and allowing the pollens to stick to the body of the insects, before they leave the flower. But this happens in some of the species only.
<u>Answer: Beetles and flies</u>.
