brain. The genetic sequence of Species B is more similar to Species C. What is the
most accurate evolutionary relationship between these three species?

A. None of the species are related.
B. Only Species B and C share a common ancestor.
C. Species B and C are more closely related.
D. Species A is the ancestor of both Species B and C.

The diagram below shows the layers of a rock having a trilobite: a rock column labeled rock is shown. the column has three layers. the bottommost layer of the rock has one shaded rhomboid shape, the middle layer has a rhombus with a diagonal along with two identical organisms marked as, trilobite, in the key, the top layer has two semicircles. a key is shown on the right side of the diagram. the shaded rhombus is marked as a, the rhombus with the diagonal is marked as b, the semicircle is marked as c which statement about the rock fossils is true?
