Hi, I can provide you with general information on molecular evolution. Molecular evolution refers to the changes in DNA sequences over time that occur due to mutation, genetic drift, natural selection, and other evolutionary forces. These changes can accumulate over generations and lead to the formation of new species or the extinction of existing ones. One way to study molecular evolution is by comparing the DNA sequences of different organisms and looking for similarities and differences. By doing so, scientists can infer the evolutionary relationships between species and reconstruct the evolutionary history of life on Earth.
