Question

What are the three principles that result in natural selection?

Answer 1

Natural selection:

1. Natural selection is the mechanism proposed for evolution by Charles Darwin.
2. It states that the species that are able to adapt to their changing environments are naturally favored for survival.

The principles that result in natural selection are as follows:

1. Variation – Individuals have varying traits in a population. Depending on whether or not these traits assist the organism to adapt to the changing environment determines the selection of the species for survival.
2. Inheritance – The parents determine the character traits that are passed on to the offspring.
3. Competition – Since several species live together with limited resources, there occurs competition between the individuals of the same species as well as between different species. The traits and adaptability of the species are what determine which organism or species survives the competition.
