Final answer:

Other causes of evolutionary change include mutation, genetic drift, gene flow, and non-random mating.

Step-by-step explanation:

Evolutionary change can be caused by various factors other than natural selection or sexual selection. These include:

  1. Mutation: Mutations introduce new genetic variation into a population's gene pool.
  2. Genetic drift: Genetic drift occurs when the allele frequencies in a population change randomly due to chance events. It is more likely to occur in small populations.
  3. Gene flow: Gene flow happens when individuals migrate and introduce new alleles into a different population. It can alter the allele frequencies in the population receiving the migrants.
  4. Non-random mating: Non-random mating occurs when individuals choose their mates based on specific criteria, such as selectivity for certain traits. This can lead to changes in allele frequencies over time.
