Final answer:
Our genome contains remnants of its own history. The study of genetics and genomics has allowed us to understand the relationships between living things and the workings of evolution.
Step-by-step explanation:
Our genome contains many segments that are remnants of its own history. DNA is the genetic material passed from parent to offspring for all life on Earth. The study of genetics and genomics has allowed scientists to understand the relationships between living things and the workings of evolution. By analyzing gene sequences, scientists can determine common ancestry and construct phylogenetic trees.
