Evidence for Evolution #1

According to the Law of Superposition, which rock layer is the oldest in this image?

• Layer A

• Layer B

• Layer C

• Layer D

Which of the following explain why we DO NOT have a complete fossil record of all life that’s ever lived? Pick 3

• Fossil formation requires the physical and biological conditions to be just right, which is quite rare

• Fossils must be extremely close to the Earth’s surface to have a chance of being found.

• Fossils can be destroyed when rocks erode, melt, or change composition.

• All the fossils from millions of years ago do not exist anymore

• We do have a complete fossil record, as scientists have found millions of fossils over the years

What is this an example of?

• vestigial structures

• embryology

• homologous structures

• fossil record

The picture shows the members of the Camelidae family. The physical features and the geographical origin of these animals provide evidence that - 

• they live in the same type of environment.

• have slowly evolved to become herbivores.

• have a common ancestor.

• exchanged DNA in the past.
