Quizlet review

11/21 - 11/26 LE

Classification worksheets for the LE 2A section should take two days.
Plant adaptations worksheet is for LE 2B and should take two days.

This is an excellent movie on Human evolution.  It should be watched in the 2A section and will likely not get finished in the 2 days 11/25 & 26. It should be finished in the 2B section on 11/26

This is an excellent movie on Human evolution.  It should be watched in the 2A section and will not get finished in the 2 days 11/25 & 26. It should be finished in the 2B section on 11/26.

If any don’t play just go back and skip them.  You can try later. Feel free to discuss any of the sections.

Speciation & Process

Objective: To explore and understand the process of evolution including the concept of  speciation and its parts. 

Video http://www.youtube.com/watch?v=2oKlKmrbLoU  Speciation- Of Ligers & Men - Crash

http://evolution.berkeley.edu/evosite/evo101/VSpeciation.shtml  

Animation http://bcs.whfreeman.com/thelifewire/content/chp24/2402001.html

What is the definition of species?

What is speciation?

What conditions are necessary for speciation to occur?

Name two places that geographic isolation can occur.  Describe how this makes speciation possible.

Tell a story. Write this on the back, or on a separate piece of paper.

Now that you know all about how speciation happens in real life, write your own speciation story. Your story should include the following details:

·         The following concepts should be included in your story

o    Genetic drift, bottleneck effect, founder effect, gene flow, and/or mutation (include at least 1)

o    Natural selection (directional (things move to an extreme), stabilizing (things kind of average),, and/or diversifying (species splits into two different)- include at least 1)

o    Modes/mechanisms of speciation (e.g. geographic speciation, Genetic barriers, temporal or reproductive isolation, etc - include at least 1)

·         The background - set the stage, describe the organisms involved - where do they live? what do they look like? what do they eat? what is their life cycle?

·         The details of the speciation event - set the stage and tell the story. What happened? How did one species become multiple species? Your details should correspond to actual modes and mechanisms of speciation you studied.

·         The aftermath - what has changed? Again describe the organisms involved, now that a speciation event has occurred. What's different, and what has remained the same?

11/20 Extinction LE

Task 

You have just taken on a new job as a paleotologist.   Your boss has just given you your first assignment. Your responsibility is to learn about 5 different animals that are now extinct.  You will describe 3 ways in which these animals may have become extinct while investigating 3 ways to prevent more animals from having the same demise or from being placed in the endagered animal list.  You will do  research to see how long ago the 5 different animals that you have selected became extinct by providing a time line for each animal.  Lastly, you will fill out a chart that lists all the information that you have learned about extinct species tp present to your boss.

Processes---You will begin your task by looking at the following Web sites/resources given here to find information that will enable you to complete your chart on extinct animals. Resources http://www.ypte.org.uk/environmental/extinction/2       Extinction---Visit this site to describe the three ways in which extinction generally occurs. This is a great way to introduction you to the concept of extinction. http://timelinesdb.com/listevents.php?subjid=785&title=Extinction     Timelines – Extinction---Visit this site to survey the timeline and history of the extinction of animals beginning with the Worst Mass Extinction in Earth’s History up until now.  http://www.dosomething.org/tipsandtools/11-facts-about-endangered-species      11 Facts About Endangered Species----visit this site to examine 11 facts about endangered species.  Facts About Endangered Animals----Visit this site to learn about the four ways in which endangered animal species are classified   a) vulnerable, b) threatened, c) endangered and d) extinct species. http://www.ehow.com/list_7442338_causes-extention-plants-animals_.html       What Causes the Extinction of Plants and Animals---Visit this site to read about the causes of the extinction of plants and animals. http://www.fws.gov/laws/lawsdigest/esact.html      Endangered Species Act of 1973----Visit this site to read about the Endangered Species Act of 1973 which is a federal action put in place in 1973 established to protect species that may be listed as endangered or threatened http://www.oum.ox.ac.uk/thezone/animals/extinct/ Museums are probably the only places you can see extinct animals and often the only places you can see some endangered animals. Although we prefer animals to be left in the wild today, scientists can use the information they gain from museum collections to understand more about the animals still in the wild. http://www.endangeredspeciesinternational.org/overview1.html Of the 44,838 species assessed worldwide using the IUCN Red List criteria, 905 are extinct and 16,928 are listed as threatened to be extinct.  Now that you have completed your research on the extinction of animals, you will prepare a chart that organizes your research for your boss to review and evaluate

      1.       In column 1 you will name five animals that have become extinct. 

2.      In column 2 you will give a time frame in which the animals were categorized as extinct

3.      In column 3 you will state how the extinct animal is classified.

4.      In column 4 you will name one way in which you think that the extinction occurs. 

Chart --------Extinction of Animals 

Complete the Chart by filling in the correct information about the Extinction of animals.

Name 5 animals that are now extinct

Time Frame in which animal was categorized as extinct

Describe how the extinct animal is classified

Name 1 way in which you think the extinction occurs

Why Does Evolution Matter Now activity

Why Does Evolution Matter Now? 

Evolution and Antibiotic and Pesticide Resistance

When people go to the doctor's office, they expect to be cured. They don't like to be told, "Go home, drink lots of fluids and rest, and you will get better." They want a more proactive approach. Often, doctors prescribe antibiotics just to make their patients happy, even if the antibiotics cannot treat the illness at hand. As a result, antibiotics become more prevalent, the microbes they attack are more likely to develop resistance, and over time the antibiotics become ineffective. Learn about why some diseases have become antibiotic-resistant and how you can help address the problem.

Misuse of Antibiotics

1. View "Why DoesEvolution Matter Now?" Travel inside a Russian prison to see the impact of evolution on the lives of the inmates and the surrounding community. This video describes the transmission of tuberculosis and the evolution of multiple drug-resistant strains of TB.

2.  Answer the following questions about the video segment on a separate sheet of paper:

Why is the Russian prison system considered to be "ground zero" in the fight against TB?

What is responsible for the evolution of TB strains that are resistant to multiple drugs?

How does the misuse of antibiotics affect the evolution of disease-causing bacteria? Use the theory of natural selection to explain the growing resistance to antibiotics.

Why should we care about a resistant strain of TB in Russia?
