|
Scientists discover that cells from two species of organisms are made up of similar proteins, suggesting a close evolutionary relationship. If the scientists do further biochemical analyses, which additional finding would support this conclusion?
|
|
The fossils of both organisms are found relatively close to each other in the fossil record.
|
|
|
The anatomical structure of both organisms is similar.
|
|
|
The DNA nucleotide sequence of both organisms is similar.
|
|
|
Both populations of organisms have undergone natural selection over time.

Explanation:
Detailed explanation-1: -Similar structures that related species have inherited from a common ancestor. Structures found on one species that have the same basic structure and embryonic origin as those found on another species determines that those two species share a common ancestor.
Detailed explanation-2: -Evidence for evolution: anatomy, molecular biology, biogeography, fossils, & direct observation.
Detailed explanation-3: -the fossil record of change in earlier species. the chemical and anatomical similarities of related life forms. the geographic distribution of related species.
