explain why the following are required for evolution of a species?

Question

Reproduction :

Different Adaptations (Variability)

Competition

Answer 1

Reproduction passes the genetic variation to the next generation and spreads it through the gene pool.

Variations are the raw materials for evolution. Natural selection chooses the variations that are best suited for the environment. Without variation, all individuals in the population would either survive or die.

Competition is the mode of selection: competition for mates, for space, for food, for territory, for nesting sites, for other resources.
