Sewall wright’s metaphor of an ""adaptive landscape"" that includes ""peaks"" and ""valleys"" is used widely in evolutionary biology. natural selection will always move populations’ mean fitness up the peaks. which influence is most likely to cause a population to move away from a fitness peak towards a valley?

Genetic drift

Explanation:

Genetic drift: This is also known as the Sewall Wright effect or allelic drift.

It is described as the amendment in the prevalence of an existing or living gene variant i.e allele in inhabitants due to random or casual sampling of organisms. An inhabitant's allele frequency is defined as the fraction or fragment of the copies of one particular gene that share a specific form.
