|
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.
|
Detailed explanation-1: -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.
Detailed explanation-2: -Evidence for evolution: anatomy, molecular biology, biogeography, fossils, & direct observation.
Detailed explanation-3: -Anatomy and Embryology Another type of evidence for evolution is the presence of structures in organisms that share the same basic form. For example, the bones in the appendages of a human, dog, bird, and whale all share the same overall construction (Figure 11.11).
Detailed explanation-4: -Molecular similarities provide evidence for the shared ancestry of life. DNA sequence comparisons can show how different species are related. Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved.
Detailed explanation-5: -Fossils, anatomy, embryos, and DNA sequences provide corroborative lines of evidence about common ancestry, with more closely related organisms having more characteristics in common.
