Final answer:
Genetic evidence, such as DNA sequencing, supports the fact of evolution by showing the common ancestry of species and how they have evolved over time.
Step-by-step explanation:
One powerful way the science of genetics supports the fact of evolution is through the study of DNA. Genetic evidence shows that species share a common ancestry and have evolved over time. DNA sequencing has also allowed scientists to trace evolutionary relationships between different species. For example, comparing the DNA of humans and chimpanzees reveals a high degree of similarity, providing strong evidence for a common ancestor. This supports the theory of evolution, which explains how species have changed and diversified over millions of years.
