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.
