Wed/Thurs, 10/23 & 10/24
APES Learning Goal:
I can explain the effects of fracking on the
environment.
I can explain ecosystem diversity
Daily Question:
 What is fracking?
 What caused ecosystem diversity?

1. Fracking Notes and Paper
2. Evolution Cornell Notes
Pick Up:
Have out:
Blank Paper
Homework:
 Stamp for Chapter 7
Notes Monday, 10/28
 Evolution Cornell
Noted due Monday
• Take a blank sheet of paper out.
• Title it Hydraulic Fracking Perspective
• Click through the PowerPoint, play the youtube
links on each of the slides and watch the
video’s, take notes.
Shale
Rock –
where
the
gas/oil
is.
The Oil/Gas is in
Black.
How do we get it?
The effects on the
habitat.
Copy this down.
Two sides of Fracking Issue
Environmentalist
• Destroy the environment by
cause air, water pollution.
• Loss of habitat for local
animals.
• Aesthetically ugly
• More traffic more noise.
Industrial/Economic
• Makes jobs
• Makes money for the
federal, state, local
government.
• Be energy self sufficient
and not need to import
from overseas.
DUE in 20 minutes: On your paper pick one of these
perspectives and write a 1-2 paragraph persuasive argument
about why they are correct. Turn in when done (20 minutes)
8.5 to 8.9 Evolution and Human
Impacts
APES Learning Goal:
•I can explain the effects of fracking on the environment. I can explain the
effects of fracking on the environment.
Linear Evolution – a common
misconception
Evolution
is similar
to a tree
with
branches
Figure 8-11
Figure 8-12
Species – live, fertile offspring
Evolution:
genetic
differences of
successive
populations –
change over time
2.Macroevolution
– long term, largescale
changes.
Ex: land mammals
to whales.
How does this happen?
Microevolution - small genetic
changes in population that happen
over a short time frame
• Mutations can creates genetic diversity. Can
be harmless, lethal, beneficial, random /
unpredictable and a rare source of new traits
Reproductive Isolation
Gene pool
- All of the
genes in a
population
genetic variation –
different fur thickness
Natural selection –
beneficial adaptations
survive
End Result Evolution
Galapagos Tortoise – Different Islands
different shell shapes? Why?
Types of Natural
Selection
1. Directional
Selection – a
variation is
beneficial and the
gene pool shifts
towards one
extreme.
Stabilizing
Selection
-the extremes are
not well adapted
and the average
variations are
favored.
Example:
►Speckled peppered moths
Disruptive
Selection
– both
extremes are
Example:
advantageous
►Darwin’s finches on Galapagos Islan
and being
average is
not.
Coevolution
The flower produces nectar
that provides the perfect
nutrition for the bird, and
exists in colors that the bird
sees best. Meanwhile the
bird's beak is perfectly
shaped to drink from the
flowers. The flower provides
food for the bird, and the
bird, by drinking from
several different flowers
spread pollen between
flowers.
A tale of two Squirrels
divergent evolution – one
species becomes two
Which Types of Isolation?
•Geographic – Colorado River physically separates them
•Reproductive – one population can’t breed with the other.
So. What does Survival of the
Fittest Mean?
• The ability to SURVIVE AND
REPRODUCE is th e most fit.
• NOT (always)THE STRONGEST
– could be smallest, largest,
fastest, slowest, etc.
APES Learning Goal:
 I can explain ecosystem Diversity
Major Sources of Change
• Continental Drift
• Rapid/Gradual Climate Change
• Human influenced changes – ex. Loss of
biodiversity from deforestation.
Extinction – the loss of a species
• Background extinction rate – the rate at
which species go extinct under “typical”
slowly changing local conditions.
• Mass Extinction - Due to a major event
large numbers of species die out quickly.
– 5 mass extinctions in Earth’s history
– We are the cause of the 6th
Mass Extinctions
When the last individual of a race of living things breathes no mor
another Heaven and another Earth must pass
before such a one can be again.” --William BeeBe
Adaptive Radiation – Dinosaurs going extinct
left a lot of empty niches that were filled by
mammals.
.
Mass Extinction of
Dinosaurs
APES Learning Goal:
 I can explain ecosystem Diversity
Closure Question
PLEASE ANSWER THE QUESTION ON
THE NEXT SLIDE AND TURN IN.
A question about a pet tarantula.
• I got him about 5 months ago in June. He's most definitely
a land tarantula and ever since I got him a home to live in (a
terrarium with smooth sides) he has always been trying to
climb on the walls but his feet just slip off the walls. On
Tuesday I came home and all of his legs were on the wall
but one was still holding him up from the ground. Today,
Thursday, I got home from school and he was crawling on
the top of the wall/ceiling and it seems as if his feet now
have suction cup or sticky bottoms that allow him to crawl
on the walls. Do you think it's possible that my tarantula
could have adapted this much in less than 5 months? I was
really curious and it couldn't wait until Monday.
