Wrapping up Unit 1

Tonight look over the document in the Unit 1 folder called "The Results section."  There is additional information here on what I am looking for in the final version of your Bird Beak results.  Final due Friday.

Make sure you (or your partner) turned in the cladogram picture from the in-class activity and the Earthviewer document.  Everyone should also have turned in "Qs to go with Origins How Life Began."

The End of Q1 is next Friday.  All work needs to be in by then.

Happy studying!

End of Evolution Unit

Final assignment in Evolution is to watch portions of the Origins: How life began video (link here). Answer the questions on the document in the shared folder.

Also in the folder there is a list of topics and resources called "Evolution Study Guide."  You should at least look this over the final day before the test (Squids Friday, Jellies Monday) and come prepared with questions.

Don't forgot to make sure that you or your partner turned in the "Earthviewer" Qs.

Test on Tuesday 10/21.  Final of Results section due 10/24.  We'll talk more about the results section before the final is due.

Just kidding...evolution never ends!

Macroevolution

For HW, start reading here, and read to the end (where it says "You have now reached the end of Evolution 101...").

Make sure your Results draft is in.  Final due Friday 10/24.

Test on Evolution on Tuesday 10/21.

Cladogram activities

What did T. rex taste like?  Go to student start, then choose folder 3.  Complete folders 3 and 4.  This activity works on the iPad.

Build a cladogram.  Start by filling out the data table.  This one does NOT work on the iPad.  Complete using a laptop in class or at a home computer.  Use your iPad to take a picture of the cladogram you drew and send this to your shared folder.

Homework: start here, read the next four pages (much of this is review of what we did in class).  When you get to the five examples of using the trees (whale, cichlid etc) you can scan/read briefly.

Speciation reading

For HW tonight read and take notes on the following:  start here, and read up through Cospeciation. Stop at Macroevolution.

Don't forget to work on your Results section draft as well.

The Results Section

Draft of a Results section due on Friday.  Check the notes in the shared folder.

Here's what you should include for EACH of the three parts that we did (Natural Selection on Day 1, Mutation and Gene Flow on Day 2):

• A data table
• A graph or chart the BEST shows the changes in allele frequency that occurred over the generations
• A short paragraph describing the results in words along with any trends that occurred

You should also include a data table and short paragraph about the seeds on the island (from Day 1), as well as the Chi-squared analysis for Natural Selection (you can either type it out or write it in Notability, then import it as a PDF or take a screen shot and bring it in as a picture).

When you are done everything should be on ONE document.  You'll have to decide where it is easiest to assemble it all (Notability, Drive or some other program).  Neatness and organization of your sections will contribute to the grade for the final (draft due Friday).

The snail paper and motorcycle paper are available in the shared folder if you want to take a look at real results sections.

Other processes in evolution reading

For HW tonight (Squids Tuesday night, Jellies Wed night) please read and take note on the following pages from the Berkeley Understand Evolution pages.  Most of this is similar to what we talked about in class today so you shouldn't need to be taking huge long extensive notes- just make sure you understand the processes we talked about today (sexual selection, drift, etc.).

You can use Print Friendly.com to turn these pages into a PDF, but you would have to do that for each page which could be time consuming.  You could also try copying all the text into a word doc, or take screen shots of each page.

Here is the link: Begin here.  Read up to Coevolution (also see menu on the left of the page).  Most pages are short on text and include diagrams.  Also please note that on the Genetic Drift page there is a link on the right that explains about bottleneck/founder effect.  Also here: Bottleneck and Founder effects.

Artificial selection gone too far...

Sexual Selection- video and Qs...

...now in the Unit 1 folder.  Complete and turn into your folder for credit.

Homework Credit

To clear up the confusion around turning in, homework credit etc.

1.  I decided I don't really like that turn-in form.  This is the first time I'm teaching completely electronically so some stuff isn't working out the way I anticipated.  If you put your work in the folder (the one with your name and section) that is fine.


2.  I hadn't planned on checking and giving credit to for the Beak of the Finch questions but I can do that.  If you finished Qs1 you can turn them into the folder.  Qs2, which are due on Monday, can also be turned in.  I won't be commenting/correcting them since we are discussing them in class.  But I'll give you hw credit.


3.  I haven't forgotten about your Yeast Labs.  Any day now.

Beak of the Finch Pt 2

The second selection of Beak of the Finch is in the folder, along with the questions.  You should jot down notes to answer the questions but they don't need to be paragraphs or even sentences.  Just be ready for discussion.

I'm posting this now so it is available but it isn't due until Monday.

Reading- The Beak of the Finch

The Beak of the Finch recounts the story of one of the first studies to actually show evolution happening as researchers watched.  The husband and wife team of Peter and Rosemary Grant studied the finches of the Galapagos Islands for decades, sometimes witnessing evolution (that is, change in the relative frequency of various genes) occur from one season to the next.

For homework read the posted selection from the book.  Then answer the questions and turn them into your folder.

Weekend Homework

Up next we'll be taking an in-depth look at Evolution.  For Monday please watch up to 22:30 of this video (From the 2001 PBS Series Evolution, Episode 4: The Arms Race).

You should pay attention to the two stories presented in this section: the arms race between the snakes and the newts, and the evolution of antibiotic-resistant TB bacteria.

Questions to think about:  How did the newts evolve such a potent poison?  How did the snakes evolve resistance to this poison?  Why do bacteria evolve so rapidly compared to people (as in, how come they became resistant to medicine and we didn't become resistant to them)?  Why would certain individuals in each of these populations survive or perish?

Take some notes on these two stories and jot down any ideas or answers you have regarding these questions so we can discuss next class.

Have a good weekend!
