What does vertical descent with modification entail?

Vertical descent with modification refers to the process of evolution where genetic traits are passed down from one generation to the next through inheritance, with modifications that arise over time. This framework illustrates how species evolve as they inherit genetic information from their ancestors, leading to gradual changes in traits due to environmental pressures, natural selection, and mutations that can arise through processes such as sexual reproduction.

The concept emphasizes the role of genetic variation and how traits can be impacted or modified as they are passed down, which aligns perfectly with the explanation of how traits evolve. By combining genetic material from both parents during sexual reproduction, new combinations of traits can emerge, enhancing the potential for adaptations to different environments.

This understanding lays the groundwork for the broader principles of evolutionary biology, including natural selection and diversification of species over time.
