What can mutations eventually lead to in terms of species differentiation?

• A. Stagnation of species development
• B. Activation of reproductive barriers
• C. Introduction of new genetic characteristics
• D. Reduction of biodiversity

Answer: (C)

Mutations are changes in the DNA sequence that can introduce new genetic variations within a population. These alterations can lead to the development of new traits that may provide individuals with advantages in their environment, potentially enhancing their survival and reproduction. As these mutations accumulate over generations, they can result in significant differences between populations, which may eventually lead to the formation of new species. This process is a fundamental mechanism of evolution, as it increases genetic diversity and allows populations to adapt to various ecological niches. The introduction of new genetic characteristics is essential for speciation because it provides the raw material needed for natural selection to act upon, driving the divergence of populations over time. Consequently, when populations become genetically distinct due to the accumulation of mutations, they are more likely to develop reproductive barriers, enhancing the chances of speciation.
