Homologous structures are the similar structures due to shared ancestry. The organism with homologous structures are all the descendants of a common ancestor.
Answer:Mutations in these genes can produce new or altered traits, resulting in heritable differences (genetic variation) between organisms. ... Evolution occurs when these heritable differences become more common or rare in a population, either non-randomly through natural selection or randomly through genetic drift.
