This is the idea that the processes occurring in the present are the same as the process that occurred in the past and will continue to occur in the future.
What is uniformitarianism?
100
This is process by which organisms that are best adapted to their environment survive and reproduce, passing their traits on to their offspring.
What is natural selection?
100
This law states that in an undisturbed horizontal sequence of rocks, the oldest rock layers will be on the bottom, with successively younger rocks on top of these.

This would most likely happen over time to a species without variation when there is a significant change in the environment.
What is extinction?
300
Identify and describe one possible explanation for mass extinctions.

Use the principle of uniformitarianism to make an inference about a modern whale species and its ancestor the "walking whale".
What is the "walking whale" inhabited land and over many generations, it began to inhabit an aquatic environment and slowly changed its skeletal form.
400
Identify a difference between Lamarck's and Darwin's theories of evolution.
What is (multiple answers: Lamarck- acquired traits passed on/Darwin- inherited traits passed on; Lamarck- organisms can change themselves over lifetime/Darwin- organisms are born with different traits that help them; Lamarck- change by hard work, practice/Darwin- change is caused by differences in genes)?
400

What is they are younger?

500
This is how scientists determine when a geological era begins and ends.
What is changes in the fossil record?

Identify two pieces of information the fossil record provides about past life.
What is (multiple answers: the structure of organisms, what they ate, what ate them, in what environment they lived, and the order in which they lived)?

This evidence explains how ancient coral reef fossils can be found high in the mountains far from any sea.
What is land that was uplifted to form the mountains was once covered by the sea?
500
Under ideal conditions, bacteria have a generation time of about 20 minutes. Humans have a generation time of about 20 years. Which would you expect to evolve faster?
What is bacteria? (Their populations go through so many more cycles of reproduction. More new species gives more chance of evolution)
