Essential Question: How does the evidence of geology, fossils, and comparative anatomy support the theory of evolution?
Learning Target: I can describe who Charles Darwin was and his inference about life on earth.
Learning Task: I will watch short film clips to learn about Charles Darwin and the inferences he made about life on Earth.
I can read about two different theories about how evolution occurred..

Our beliefs are important to us. They are valid and serve valuable purposes in our life
Science isn’t about telling you what to believe – or about telling you that what you believe is wrong. Rather, Science is about UNDERSTANDING the world around us. You don’t have to believe it, but you should understand it.
Today we will watch two video clips from the PBS Series Evolution –
Evolving Ideas
You will copy the questions for each section into your lab notebook before watching, and then answer the questions while you watch.
Video: Evolution Questions 11
Segment 1: Isn't Evolution Just a Theory?
1.

1. Where is the history of life held?
2. How are whales similar to us? How are they different?
3. Whales have flippers, but what are the bones similar to on the inside?
4. What reason do scientists give for a fourlegged animal moving closer to water and giving rise to modern whales?

Extinction of species is common.
Extinction of species occurs when the environment changes and the individual organisms of that species do not have the traits necessary to survive and reproduce in the changed
environment.
Extinct:
The Dodo was a large, flightless bird
It was a relative of pigeons and doves
The last dodo died sometime in the late
17th century http://science.discovery.com/creatures/10-extinct-species.htm
Extinct:
Stegosaurus lived way before Triceratops showed up
Tyrannosaurus wasn't feasting on Apatosaurus
(he had been extinct for millions of years by that time)
They were all gone by the time human beings came around http://science.discovery.com/creatures/10-extinct-species.htm
Extinct:
These pigeons once blackened the sky as it roamed in flocks numbering in the billions
Westward-bound settlers chopped down the birds' habitat at an alarming pace.
In less than 100 years, this species was in a lot of trouble.
The last passenger pigeon died in a Cincinnati zoo in
1914. http://science.discovery.com/creatures/10-extinct-species.htm
Extinct:
Has been extinct for over
10,000 years
The cat itself was about the size of a modern-day lion (if not a bit shorter), but far more robust
This fierce predator once roamed freely in the grasslands and forests of
North and South America
We should probably be happy we're not living in the
Ice Age!

Evolution Vocab 12
Darwin –a naturalist who proposed and provided scientific evidence that all species of life have evolved over time from common ancestors
• Theory – a explanation that ties together many hypothesis and observations
Natural Selection – survival of the fittest organisms that are the best adapted to their environment and will live long enough to reproduce and pass on those adaptations
