Question

What is evolution? What are the factors leading to evolution and how do these factors lead to evolution?

Answer 1

Evolution is the change in the inherited traits of a population from generation to generation.

Some of the factors that lead to evolution of species are
1. Genetic drift
2.Gene flow.
3.Mutations.
4.Sexual selections.
5.Random selections
6.Natural selection.

Genetic drift is a change in allele frequencies due to chance.

Gene flow is the movement of alleles between populations.

Mutations produce the genetic variation needed for evolution.

Sexual selection selects for traits that improve mating success.

Natural selection selects for traits advantageous for survival.

Random selection
