Hello Monday!
The Earth is 4.56 billion years old…the same age as the Moon and the Sun.
The dinosaurs became extinct before the Rockies or the Alps were formed.
When a flea jumps, the rate of acceleration is 20 times that of the space shuttle during launch.
If our Sun were just inch in diameter, the nearest star would be 445 miles away.
Astronauts cannot belch – there is no gravity to separate liquid from gas in their stomachs.
EQ: What evidence is there to support evolution?EQ: How do fossils help biologists understand the
history of life?EQ: How have living things changed over time?
Mon. 3/14 – review of Sect. 15.1 Tues. 3/15 – review & quizWed. 3/16 – focus lesson- evolutionThurs. 3/17 – African Swallowtail ActivityFriday 3/18 – genetic drift activities
Action Plan for March 14-18, 2011
write 5 things for discussion afterwards
I will give you time to read the chapter. Pg 393-403.
Answer the questions and study for the quiz tomorrow
Let’s finish up 15.1
1. Who is Charles Darwin? (What were his ideas? What did he study? What do you think of his ideas?)
2. What is Natural Selection? (Is adaptation, mimicry, camouflage, reproduction all part of natural selection?)
3. Define and give an example of homologous structures.
4. Define and give an example of analogous structures
5. Define and give examples of vestigial structures
Know the answers
Homologous structures share a common Origin but may not be adapted for similar functions-example: a dolphins flipper is homologous to the forelimbs of other mammals.
Analogous Structures are adapted for similar functions but do not have common origin.
-example: bat wings,(have bones) fly wings (have membranes)
Vestigial –remnants of organs or structures that had a function in an early ancestor . ex: ostrich wings; appendix in humans; pelvic bones and hind limbs in many snakes.
1) Species have great fertility. They make more offspring than can grow to adulthood.
2) Populations remain roughly the same size, with modest fluctuations.
3) Food resources are limited, but are relatively constant most of the time. From these three observations it may be inferred that in such an environment there will be a struggle for survival among individuals.
4) In sexually reproducing species, generally no two individuals are identical. Variation is rampant.
5) Much of this variation is heritable.

African Swallowtail ActivityThe African Swallowtail Butterfly is a non-toxic
butterfly but has color forms that resemble those of toxic species, and are avoided by
predators as a result.
Thursday March 17
1. Divide your group into birds and butterflies. Butterflies place the 15 pieces of paper randomly on the table with the markings face up.
2.The pieces of paper with an X written on them represent poisonous butterflies: those with ST represent swallowtails, which are not poisonous. Butterflies, record the number of swallowtails of each color in your notebook, using the table below.
3. Butterflies; flip the pieces of paper over and tell the birds to open their eyes.
4. Birds; draw up to 6 pieces of paper (total) from the table to represent predation. If you “ate” any poisonous butterflies, do not draw another piece of paper that color for the rest of the activity. (You may not always be able to draw 6)
5. Birds; close your eyes. Butterflies; repopulate by duplicating every piece of paper that remains. Write X and ST on the appropriate new pieces of paper.
6. Butterflies, record the number of swallowtails on the table.Repeat steps 3-6 two more times to complete three trials
