Mutations introduce genetic variation, but most mutations do not immediately result in an advantage or disadvantage. Explain how a mutation that is initially neutral could later become beneficial or harmful due to changes in the environment. Use a real or hypothetical example to support your answer.

A population of lizards is separated by a volcanic eruption, forming two isolated groups. Over many generations, small genetic differences accumulate due to mutations, natural selection, and genetic drift. After thousands of years, individuals from the two groups come into contact again but can no longer successfully mate. Which statement below best summarizes what this scenario has demonstrated about evolution?

A researcher is studying the evolutionary history of two mammal species. When comparing their DNA sequences, the researcher finds that they differ by a known number of mutations. Using the molecular clock hypothesis, what additional information is needed to estimate when these species last shared a common ancestor?
