Which of the following best describes how comparative anatomy can be used to determine the evolutionary relationship between two organisms?
a. organisms that have a great deal of physical similarity are more likely to share a common ancestor than two organisms with few physical traits in common.
b. comparing the physical traits of two organisms makes it possible to determine how long ago they shared a common ancestor.
c. studying the physical differences between two organisms will show which organism evolved from the other.
d. two species that have few physical traits in common do not share a common ancestor and most likely evolved from different species.

Two species that have few physical traits in common do not share a common ancestor and most likely evolved from different species.

Explanation: Took the test got it right

Two species that have few physical traits in common do not share a common ancestor and most likely evolved from different species.

Explanation:

The species that do not share the common physical traits in large number are likely to have evolved from different species. These species would not share the common ancestor. Absence of common physical traits between two species sets them apart from each other in terms of evolution. In general, the species with common ancestor are likely to share many physical traits with each other.

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.
