The 4 factors affect evolution, according to Darwin’s Origin of Species are;

Variation

Heritability

Competition

Differential survival

Variation ensures that there is variability of population traits on which selection pressures will apply.

Heritability means that the traits must be able to be passed down to offsprings through gametes.

Competition occurs when the individuals in the population compete for limited resources

Differential survival occurs due to competition for resources and other selection pressures. This result to the survival of the strongest and weeding out of the weak from the population.

Base on the Dawins theory as regards Origin of species, The factor that can be considered as one that affect evolution are;

Competition

Differential survival

Variation

Heritability

Therefore, the theory is about evolution of organism.
