✓

Answer

Comparing of DNA is known as molecular phylogeny species deduced from fossils record to be closely related are more similar in their DNA than as species thought to be more distinctly related.
Tracing evolutionary relationships between organisms is called as phylogeny while studying structures of various DNAs to establish evolutionary relationships between them is called as, while studying structures of various DNAs to establish evolutionary relationships between them is called as molecular phylogeny.
