When was Darwins Origin of Species 1859
written?
Describe Darwin's theory of natural There is, he argued, tremendous variation
selection. among the members of any given species.
Some of these variations are well suited to
current conditions; others are not. Individuals
with favorable variations are more likely to
survive and reproduce, so succeeding
generations are more likely to show helpful
characteristics. Thus, features that contribute
to survival are "selected" by the environment, a
process Darwin called natural selection.
Was Darwin aware of the genetic no
basis for evolution by natural
selection?

selection?
Intelligent direction isn't required. The
environment "selects" desirable characteristics
and spurns undesirable ones.
What are mutations? Abrupt changes in genes.
What can cause a mutation? Can be caused by exposure to radiation and
certain chemicals and perhaps by viral
infections.
In what case will mutation be passed when mutations occur in genes of reproductive
on to the next generation? cells (sperm or ova)
Can mutations occur in any cell of yes

Will offspring with mutated genes no
necessarily display the mutation?

Are mutations always detrimental to Many of these changes are simply of no
survival? consequence, one way or the other
Occasionally can be useful to survival. (new
horn mutation useful for defense)
What is a reflex? A reflex is a relationship between a specific
event and a simple response to that event. A
reflex is a relationship between certain kinds of
events.
Give an example of a reflex. Food in the mouth elicits the salivary reflex, the
flow of saliva that begins the process of
digestion.
What is reflex failure? When can it Reflex failure is when a reflex fails to function
occur? properly.
This can happen as a result of:
-allergic reaction to medication
-injury or disease.
-excessive alcohol or other drugs that depress
the central nervous system.
Reflexes are highly ___________ stereotypic
that is, they are remarkably consistent in form,
frequency, strength, and time of appearance
during development.

What is sensitization? Give an Eliciting a reflex response can increase the
example. intensity or probability of the response to
stimuli.
Hearing a loud noise that makes you jump can
make you more sensitive to noises that arent as
loud.
What happened when Kelly Powell The rats showed an increased response to
and Stephen Holtzman (2001) gave morphine (i.e., sensitization) for up to three
rats morphine for one to four days months after their last dose.
and then tested their reaction to the
drug after a period of abstinence?
What is habituation? Give an Repeatedly evoking a given reflex response will
example. result in a reduction in the intensity or
probability of the response.
Cats slowly become used to a loud noise when
exposed to it multiple times.
Define a FAP. Give an example. A series of interrelated acts found in all or
nearly all members of a species.
When confronted by a threatening dog, the
house cat arches its back, hisses, growls, and
flicks its tail. These acts make the cat appear
larger and more formidable than it really is and
may therefore serve to put off an attacker.
What were FAP called in the past? Instincts
