unite? - ANSWER✔✔ Unites the world of purposeless, meaningless matter and
motion and the world of meaning and purpose design
What were the consequences of Darwin's ideas on British society? - ANSWER✔✔
evolution was unorthodox against natural history in Great Britain, jeopardized the

Galapagos? Why is this significant? - ANSWER✔✔ He didn't label the finches by
island. There were separate species for each Galapagos Island
When Darwin realizes he needs birds from the Galapagos with better records than
what he kept, he goes to Captain Fitzroy to ask to see his collection. How do
Darwin and Fitzroy differ on their views of finches and why are they important? -
ANSWER✔✔ Darwin believed that finches could have been blown from South
America and evolved through generations depending on where they ended up.
Fitzroy believed that God put the finches there. Showed how the British were not
open to the idea of evolution and only focused on the church's views.
In looking over the bones on the table, Darwin ponders if the globe has undergone
such profound changes in its history geologically, surely all living creatures must
,have changed with it to adapt to new conditions. Or otherwise they would have
perished. He says there must be a new law which does what? - ANSWER✔✔
Causes new species to appear in place of extinct ones
Later, in the pool room with his brother, Darwin suggests that perhaps there is a
tree of life. What is this tree of life? What is the "bottom line" of his idea? -
ANSWER✔✔ Each new species springs from the parent tree in chutes, these
chutes branch and divide, some branches die out and some keep growing, the trunk
is the ancient common ancestor
Chris Schneider conducts research in Ecuador near base of Andes mountains and
further upland. What does he hope to discover? - ANSWER✔✔ How changing
environments might trigger the evolution of new species
What observations did Darwin make on the finches he brought back from the
Galapagos? - ANSWER✔✔ They had uniquely shaped beaks adapted to the
different foods on the islands
What was Darwin's thinking regarding the origin of the different finches? -
ANSWER✔✔ They had descended from a common ancestral population that had
flown over from the mainland
What does the example of the adaptations of the praying mantis illustrate with
regards to natural selection and the evolution of such extreme adaptations? -
ANSWER✔✔ Mantis' must have gone through many modifications in order to
transform their backs to look like leaves in order to camouflage and avoid
predators
Depends where they are in the rainforest, it would have a longer chance of living
,Tom Smith's research on hummingbirds in the Andes points to a very key event
that can lead to the emergence of a new species. What is this? - ANSWER✔✔
Creation of and adaptation to a new environment. Changes in beak length. Changes
in environment can change characteristics of a species.
When are animals considered new species? - ANSWER✔✔ when the population
changes so much that they cannot reproduce with one another
HIV has the capacity to evolve, no matter what you give it. Michael Saags has seen
HIV evolve into new varieties over the last several years. The virus is constantly
changing, subject to the forces of natural selection in the environment of the
patient's body. Watch the animation carefully! What is happening to HIV once
inside a patient's white blood cells? How does drug resistance happen? -
ANSWER✔✔ Once inside a patient's white blood cells the virus replicates its
DNA very quickly. The drug resistance occurs because many forms of the virus are
created and their genetic variations tend are too many some drugs to work
effectively.
Dan Dennett states that the process of natural selection feeds on
________________________ ____________________________________. -
ANSWER✔✔ randomness, accidents, contingency, and gradual improves the fit
between whatever organism they are and the environment but no predictably of
what accidents
In 1997, Veronica Miller (Goethe University, Germany) made a major discovery.
Describe what she found. - ANSWER✔✔ The doctor discovered that after 3
months off of the anti HIV medication, the patient no longer had any trace of drug
resistant virus in his system.
, What had happened in Miller's patient? (Watch the animation very carefully!) -
ANSWER✔✔ When the patient went off the medication it gave the non-resistant
strains of the virus an opportunity to regrow and takeover within the patient
Richard Owens and Darwin disagreed over why vertebrae animals had the same
patterns in limbs, back bone, etc. What was Owen's view? - ANSWER✔✔ The
blueprint that originated in "The Creator's" mind (GOD)
Richard Owens and Darwin disagreed over why vertebrae animals had the same
patterns in limbs, back bone, etc. What was Darwin's view? - ANSWER✔✔
similarity means a common ancestor
What is the main difference between the way a designer would design something
and the way that nature designs something? - ANSWER✔✔ A designer creates
perfection look, while nature favors randomness which makes it more fit to survive
(imperfection)
What is an example of an imperfection in the "design" of the human eye? -
ANSWER✔✔ Retinal tear: jelly in our eye liquifies as we age causing it to tear,
jelly can seep into the space underneath, leading to detachment or blindness
nerve cells and blood vessels evolved to lie in front of the retina, interfering its
ability to form shape images
optic nerve evolved to connect to the brain through a hole in the retina
Dan-Eric Nilsson's model shows how a primitive eye spot could evolve through
intermediate stages to become a complex, human-like eye in less than ½ million
