In Natural selection fittest organism is selected naturally, which is able to cope up and is adaptable to all kind of situations like variations in weather, temperature, shelter, gaining of nutrition, genetic drift, etc.In artificial selection, organisms with the desired traits are been selected and further, they are been genetically modified with the advancing technologies evolving in biology. Hence we can say that natural selection is what natures chooses at its best, while the artificial selection is what humans choose on the kind of its requirements.

Answer:

ARTIFICIAL SELECTION AND NATURAL SELECTION –

Natural selection is the process of evolution of species whereby characteristics which help individual organisms to survive and reproduce are passed on to their offsprings.

Artificial selection is the process of modification of a species by human intervention so that certain desirable traits are represented in successive generations.

WHAT ARE EVOLUTION ?
