The amount of time that has passed since two species last shared a common ancestor: cannot be determined, due to gaps in the fos
sil record. can be determined by the relative amounts of uranium-238 found in the bones of individuals from each species. can be determined for prokaryotic species but not eukaryotes. cannot be determined, due to the fact that most species pass through the same embryological stages. is revealed by the degree of similarity in sections of their DNA.
is revealed by the degree of similarity in sections of their DNA
Explanation:
phylogenetic analysis of DNA sequences of two different species are compared and the level of similarity between nucleotide sequences in DNA help to identify their relatedness.
