2. the abiotic factors that made life inhospitable for many organisms in the early earth.
3. which organisms were able to survive these conditions and where they can still be found today.
4. two main theories in Ch 17-2 that describe how life has come to exist as we know it today.
5. Because of the time scale that these early changes occurred, we can describe these life changes as _____________ evolution.

Evolutionary Evidence & Animal
Entry doc: Animal Evolution letter
Watch What is the Evidence for Evolution?
1. Take notes & start researching your own animal and the lines of evidence you find in your search, start the IAKT.
sample essay
2. Navigate the UC Berkeley Museum of Paleontology Website to discover the history & evolutionary relationships of your animal. Fill-in the webquest.
Animal Examples-Vertebrates (bears, wolves, cats, whales, rats, dinosaurs)
see also (Arthropods, Chordates, Echinoderms, Corals/Jellies, Annelids, Mollusks)
finally extinct phyla (Anomalocarus, Pikaia, Trilobites, Ammonites)
3. Choose one of the following news articles to include in your lines of evidence.
The Black Ghost Knifefish, & EL level observable evidence for co-evolution.
A Look at the Woolly Maamoth's Genome, & EL level DNA evidence for extinction.
The Brontosaurus is Back, & EL level a comparative anatomy with close relatives.
Ancient Whale Swam up the African River, & EL level species distribution evidence of animal behavior.
Ancient Sea Creature Fossils, & EL level fossil evidence of numerous phyla.
Reconstructed Dinosaur (Spinosaurus) has Body Built for Swimming, & EL level predictive evidence for semi-aquatic behavior.
Corals Evolve to Adapt to Higher Temperatures & EL level observable evolution.
Sea Urchins Adapt to Acidity & EL level observable evolution.
4. Refer to class activities or the textbook as a resource for your essay:
-Use Protein Sequencing as a line of evidence
-Watch Animals in the Womb, Nat Geographic & answer questions for more information on developmental and embryological evidence.
-Comparative Anatomy: Use the San Diego Zoo Website to answer focus questions on animal adaptations.
-It's All in the Bones -A guide for looking at mammalian limb bones. This evidence supports selection and adaptation as an evolutionary mechanism in mammalian evolution.
-Fill out the Geologic Time Webquest for more information on the macroevolutionary scale, here's the link.
-Watch 100 Great Discoveries Film & questions for more on the history of evolutionary theory and discovery.
-Macroevolution: Pre-read Extinction: Case Studies- Describe the main extinction events and the evidence shown. Describe key creatures, atmospheric and temperature changes for the time period you are assigned. Fill-in the Changes Across Time Chart.
-Fossil Record Notes & Macroevolution Assessment
5. Incorporate the quizlet and an activity you will use in your presentation. (Wordle example)
