Phylogeny
Biodiversity & Evolution Step 6
How do scientists determine if species are related?
In this unit, you will learn about the concept of Deep Time and some important extinction events in the history of the Earth. You will also explore how scientists learn information from fossils and how organisms that once lived compare to organisms of today.
Section 1: The Fossil Record and Homology
- I know the terms: homology, analogy, vestigial feature, absolute age, relative age, principle of superposition, fossil, endangered, extinct, mass extinction
- I understand how scientists use the fossil record to determine evolutionary, climatic, ecological, and behavioral information.
- I understand how some extinct species are similar to species living on Earth today.
