Charles Darwin used information from the fossil record as evidence of evolution. In addition to the fossil record, all of the following provide evidence of evolution except -

• Biogeography - Island species most closely resemble mainland species.

• Anatomical/Embryological/Vestigial Structures (body structures)

• Molecular (DNA evidence)

• Analogous Structures (Similar structure, similar function)

Which of the following is not true about Fossil Evidence?

• Fossil Evidence creates an evolutionary timeline.

• Fossils found in deeper layers are older than fossils found in superficial layers.

• Fossils are actual bones that contain DNA evidence.

• Fossils that seem to disappear from 1 layer to the next most likely died out.

Vestigial structures are -

• structures that perform a similar function but are not similar in origin

• remnants of once-important structures that have slowly lost all or most of their function

• features found in different organisms that share structural similarities but may have very different functions

• preserved remains of an organism
