These sources of information are used to determine the relationships among different species. Which provides information at the species level?
A) comparison of fossil records
B) comparison of the nucleotide sequences in DNA
C) comparison of the morphology of the different species

Answer 1

Taxonomist use an eight level system to classify living things based on shared characteristics. Scientists also used shared characteristics to hypothesize how closely related living things are. The more characteristics the organisms share, the more closely related the organisms may be. For example, the platypus, brown bear, lion, and house cat are thought to be related because they share many charcteristics. These animals have hair and mammary glands, so they are grouped together as mammals. But they can also be further classified into more-specific groups.
