Most people believed in
creationism. Each species was a
divine creation that exists,
unchanging, as it was originally
created.
What did the majority of
people believe about
species in Darwin’s time?
Column 1, #1
Inheritance of Acquired
Characteristics.
What is the name of Lamarck’s
“theory” of evolution?
Column 1, #2
(1)Physical features increase
in size b/c of use or reduce
in size b/c of disuse.
(2)these changes are passed
on to the offspring.
Describe the two parts to
Lamarck’s theory.
Column 1, #3
Gradual change over a long
period of time leads to
species formation.
Charles Lyell proposed the idea
of gradualism in his book
Principles of Geology. Describe
this model of evolution.
Column 1, #4
The human populations do not grow
unchecked because death caused by
disease, war, and famine slows population
growth.
According to Thomas Malthus,
what kept the human population
in check?
Column 1, #5
The fossilized animals closely
resembled, but were not identical
to, the armadillos living in the area.
In South America, Darwin found fossils
of extinct armadillos. How did these
fossilized animals compare to the
armadillos living in the area?
Column 2, #1
Darwin discovered that the Galapagos
finches closely resembled the South
American finches.
How did the finches on the
Galapagos Islands compare to the
finches in South America?
Column 2, #2
adaptation
What is a feature called that
provides a selective advantage to
a population?
Column 2, #3
Population.
At what level of grouping of
organisms does evolution
occur.
Column 2, #4
(1) Genetic variation within every population.
(2)
Some individuals are better suited to survive and reproduce in a
particular environment.
(3) Over time, these better suited traits spread in a population.
(4) Fossils and other scientific evidence support the idea that living species
evolved from extinct organisms.
Describe the four major points of
Darwin’s theory of evolution by
natural selection.
Column 2, #5
Paleontologist.
What is the term for a scientist
who studies fossils?
Column 3, #1
Fossils form when they are rapidly
buried in sediment.
When do fossils form?
Column 3, #2
Wet lowlands, slow-moving streams,
lakes, shallow seas, and areas near
active volcanoes.
Where do fossils form?
Column 3, #3
Radiometric dating.
How can scientists estimate the
age of a fossil?
Column 3, #4
Many species have lived in environments
where fossils do not form. The body often
decays or is eaten or scattered by
scavengers before fossilization.
Why is the fossil record not
complete?
Column 3, #5
A. gorilla
Which organism shares a more
recent common ancestor with
humans?
A.gorilla b. rhesus monkey
c. mouse
d. chicken
Column 4, #1
Fewer.
If evolution has taken place, then
species descended from a recent
common ancestor should have
more/fewer (choose one) amino acid
differences between their proteins
than do species that share a common
ancestor in the more distant past.
Column 4, #2
Similar structures due to a common ancestry.
What are homologous
structures?
Column 4, #3
Vestigial structures are reduced in size
and have little or no use than they do
in other related organisms.
What are vestigial structures?
Column 4, #4
Sample answers:
(a) Forelimbs of vertebrates contain the same
kinds of bones.
(b) Hind limb in whales, coccyx (tailbone) and
appendix in humans.
Provide an example of:
(a) Homologous structures and
(b) vestigial structures.
Column 4, #5
Land or water barriers that isolate
2 or more closely related groups.
What is geographic
isolation?
Column 5, #1
Reproductive barriers that may isolate
2 or more closely related groups ex:
physical differences, different mating
seasons, may not be attracted to one
another.
What is reproductive isolation?
Column 5,
#2
Changes in food supply.
What does beak shape change
in response to according to
findings from the Grants and
Darwin?
Column 5, #3
Accumulation of differences between
groups.
What is divergence?
Column 5, #4
The differences between subspecies are usually less distinct
than the differences between species. The characteristics
attributed to subspecies generally have evolved as a result of
geographical distribution or isolation.
What is a subspecies?
Column 5, #5
