An individual attribute could increase in a population within the following 2 ways:-
(a) Natural selection: if an attribute is useful to a population, it'll increase naturally. For example – mosquitoes which are resilient against a particular pesticide will pass on its genes, so that future generations become resistant as well. The mosquitoes which are affected by the pesticide die out .
(b) Genetic drift: if a species faces a catastrophic event where most of the population is wiped out, the surviving population can pass on their traits to the following generations. This may result in a rise of the attribute within the population.

How is the equal genetic contribution of male and female parents ensured in the progeny?
Explain how sexual reproduction gives rise to more viable variations than asexual reproduction. How does this affect the evolution of those organisms that reproduce sexually?
What evidence do we have for the origin of life from inanimate matter?
Explain the importance of fossils in deciding evolutionary relationships.
