Question
Explain the struggle for existence and variation in the light of Darwin’s theory.
Answer
According to Darwin’s theory of evolution, all living organisms have variations, which are inherited traits that make them better adapted to their environment. The struggle for existence refers to the competition for resources such as food, water, and mates that occurs between individuals of the same species, as well as between different species that occupy the same ecological niche.
Darwin proposed that organisms with variations that provide them with a survival advantage are more likely to survive and reproduce, passing on their advantageous traits to their offspring. This process, known as natural selection, results in the evolution of new species over time.
