Question

which phrase best describes evolution?
any mu, that changes an organisms dna
a change in the learned behaviors of a population over time
the skills an organism learns during its life
a change in the frequency of alleles in a population over time

Explanation:

Evolution is defined as a change in the genetic composition (allele frequencies) of a population over successive generations. A single mutation (even if it changes DNA) is not evolution as evolution pertains to population - level changes. Learned behaviors (whether of an individual or a population) are not related to the genetic - based definition of evolution. The skills an organism learns during its life are also non - genetic and do not represent evolution.

Answer:

a change in the frequency of alleles in a population over time
