A well supported, testable explanation of phenomena that occurred in the natural world is a:
law
theory
hypothesis
prediction
3
The (2) main ideas with regards to the natural world that were challenged by Darwin
world was 6,000 years old and unchanging
finches are abundant
all species are fixed
don't go exploring or you fall off the edge of the world
4
Most fossils form in
sedimentary rock
rusty water
ice
the sap of ancient trees
5
Charles Darwin observation of finches of different species on the islands had similar features
have grown larger since Darwin's visit
orginated from a common ancestor
all eat the same type of food
acquired traits through use and disuse
6
Evidence that supports evolution:
all of the above
fossils
biogeography
embryology, and DNA
7
If
C
layer is 425 million years old what can you infer about the age of fossils in layer
C
they are also 425 million years old
younger than 425 million years
older than 425 million years old
8
The number/location of bones of many fossil vertebrates are similar to living vertebrates;means
the needs of the organisms
the struggle for existence
the inheritance of acquired traits
a common ancestor
9
Darwin was finally pushed to publish his book when he read essay by Huxley on Natural Selection
T
F
10
There is a great variety of breeds of dogs. This is considered artificial selection
F
T
11
The basic structure of the hemogloblin molecule is same in humans, salmon-this is homology
f
t
12
What inferences can you make about the life forms at the time layer
A
was formed
no life
no hard exoskeleton
simple lifeforms
13
The wings of a bat,arm of man,flipper of whale have similar number of bones/structure-homology
F
T
14
On the Galapagos Islands, Charles Darwin observed
similar species like the mainland-traits suited the env't
completely unrelatedspecies on each of the islands.
species exactly like thosefound on mainland South America.
species completelyunrelated to those found on mainland
15
James Hutton challenged the age of the earth-primary area of study was:
geology
archeology
genetics
biology
16
Name of Darwin's book - he states species evolving over time and the natural selection process.
The Beagle has landed
Principles of Geology
The Origin of Species
The Evolution of Populations
17
Hummingbirds and monarch butterflies both have wings-analogous structures
F
T
18
Examples of fossils include preserved:
eggs
body parts
all of the above
footprints
19
In the 1800s, Charles Lyell emphasized that
gradual geological events of past could explain the features
Earth is very young.
the human population willoutgrow the available food supply.
all populations evolvethrough natural selection.
20
Term for an inherited trait that improves an organism's ability to survive/reproduce
a hypothesis
an adaptation
a theory
an extinction
21
In rabbits the appendix used for digestion which is rich in cellulose. In humans it is small.
vestigial structure
fossil
acquired trait
natural variation
22
In 1844,Darwin published his book The Origin of Species.What are the two main points of book?
no idea
Inherited Acquired Characteristics
All species today evolved from a common ancestral species.
The mechanism that causes the change is Natural Selection
23
Darwin's Theory of Natural Selection-certain individuals survive longer-have offspring
lack of competition within the species
pocess inherited adaptations that are suited to environment
they possess adaptations developed through use
it is due to choices made by plant and animal breeders.
24

no life
iceage
no growth
25
James Hutton's ideas supported which theory about earth?
the theory of evolution
the theory of use and disuse
the theory of uniformitarianism
the theory of descent with modification

in South America
In Asia
in England
27
Which of the ideas, proposed by Lamarck,was found to be INCORRECT
organisms are adapted to their environment
living things change over time
acquired characteristics can be inherited
all species were descended from other species

29
Antibiotics are medicines that
kill insects

destroy viruses
strengthen the immune system
30
What concept about species did Georg Cuvier derive from studying elephant and mammoth bones?
