Question

1. how does the study of genetics and dna help the study of evolution? the closer the genetic similarity, the further away the organisms are the study of genetics has shown physically unrelated organisms to be genetically related it doesnt as the genetic code for different organisms is completely different the closer the genetic similarity, the closer related the two organisms could be on the evolutionary tree

Explanation:

Genetic similarity reflects evolutionary relatedness: more shared DNA means organisms share a more recent common ancestor, placing them closer on an evolutionary tree. Genetics also shows that physical similarity does not always equal genetic relatedness, and the shared core genetic code across life indicates a common evolutionary origin.

Answer:

The closer the genetic similarity, the closer the two organisms could be on the evolutionary tree
