the whirlpool of geologic time

From the beginning of time on Earth

We are now in the last section! We are going to look at all the diversity of life on Earth starting with Earth's history. Then we'll look at how organisms develop differences.

Step One - What Material are we covering?

Here are the powerpoint slides I will use for the Survey Of Life section
Have your lecture note outlines to take notes on the lectures. Video lectures are on the next page.

Step Two - How well did you understand the lecture? (Study Guide Questions)

Want to test out what you learn? We recommend you review the study guide questions at the end of the lecture. You will use these in the Study guide Discussion We put them here for your reference as well:

Study Questions: Geologic Time/Taxonomy

Most of the Eras and periods we use to define geologic times were determined by what?
What is the role of plate tectonics in evolution?
Which is the period when all the present phyla are first present in the fossil record?
The Earth is approximately how old?

When do we see the high accumulation of oxygen on the Earth probably happened
What is Taxonomy? Who is consider its inventor?
What does phylogeny mean? What are different ways of looking at it?
What is the difference between Homologous and Analogous structures?
What is the tree of life?

Study Questions: Evolutionary Processes

What are the different mechanisms of microevolution? Macroevolution?
- What are the extrinsic & intrinsic mechanisms?
- What are the types of selection? Why would one be favored?
- What is genetic drift? Founder Effect? Bottleneck?
What is the difference between homologous and analogous structures?
How do we make evolutionary trees? How do we decide who is more closely related?
What is a generalist? Specialist?

If you have questions about the questions, meet with us, or post them in thediscussion. Maybe you make some notes on the study questions after you took the quiz?
