What does the position of fossils in the rock record indicate?

• The color of the rock

• The age of the fossils

• The type of rock

• The size of the fossils

How does the depth of a fossil in the strata relate to its age?

• The deeper it is, the younger it is

• The deeper it is, the older it is

• Depth does not affect age

• The shallower it is, the older it is

What are homologous structures?

• Structures that have similar functions but do not share a common ancestor

• Structures that are similar and share a common ancestor

• Remnants of structures that once had a purpose

• Structures that are completely different in function and origin

What defines analogous structures?

• Similar structures with a common ancestor

• Structures with similar functions but different evolutionary origins

• Remnants of structures that once had a purpose

• Structures that are identical in form and function

Which structures are remnants of structures that once had a purpose?

• Homologous structures

• Analogous structures

• Vestigial structures

• Functional structures

What is the main characteristic of homologous structures?
