Question

which of these provides the best evidence for the evolution of species? 2 points photographs genetic evidence chemical composition fossil records if two organisms have similar dna, ____________. 2 points they lived close together they evolved from a common ancestor. they have different ancesters they lived far apart

Explanation:

1. Genetic evidence shows the molecular - level relatedness among species, providing detailed information about evolutionary relationships. Fossil records are also strong evidence but genetic evidence can reveal more precise evolutionary connections. Photographs and chemical composition are not the best for showing species evolution.
2. Similar DNA indicates a common genetic heritage. Organisms with similar DNA sequences likely evolved from a common ancestor as DNA is passed down through generations. Living close or far apart does not determine DNA similarity, and different ancestors would imply different DNA.

Answer:

1. genetic evidence
2. They evolved from a common ancestor.
