Answers
1
Fossil evidence shows that vestigial structures in living organisms
were useful to their ancestors
do not fill gaps in the fossil record
are not found in ancient organisms
have always been vestigial
2
Darwin observed finches of
different species
had similar characteristics suggesting
have the ability to interbreed
descended from a common ancestor
all eat the same type of food
acquired traits through use and disuse
3
Darwin began to formulate his concept of evolution by natural selection after
agreeing with Lamarck about the force behind evolution
observations of many species and their geographic location
reading the writings of Wallace
experimentation with animals
4
If number and location of bones in fossils are the same as in those living, it would be due to
the inheritance of acquired traits
the struggle for existence
the needs of the organism
a common ancestor
5
When a farmer breeds on his or her best livestock, the process is called
artificial selection
natural selection
artificial variations
survival of the fittest
6
The forelimbs below are similar in structure but have different functions. What are they?
analogous structures
vestigial structures
homologous structures
fossil structures
7
The finches that Darwin found on the islands displayed different adaptations which were
number of eggs in each nest
birds' different shaped beaks
length of birds necks
similarities of birds' embryos
8
Which phrase best defines evolution by natural selection?
process of change in species over time
an adaptation of a species to its environment
a sudden replacement of one population by another
changes in a species as it becomes more perfect
9
What is the study of the distribution of organisms around the world?
paleontology
natural selection
geology
biogeography
10
What is the term for a feature that allows organisms to survive better in their environment
homologous structures
vestigial structures
variation
adaptation
11
Modern sea star larvae resemble some primitive vertebrate larvae. Primitive vertebrate larvae
share a common ancestor with sea stars
evolved from sea stars
belong to the same species as sea stars
evolved before sea stars
12
What is the best way to determine if species are related or not?
molecular and DNA evidence
look at their brothers and sisters
fossil records
time periods
13
On the Galapagos Islands, Darwin observed
species exactly like those in South America
completely unrelated species on the islands
species completely unrelated to those found in South America
somewhat similar species with traits suited for environment
14
The hind leg bones in the whale are examples of (not really used anymore)
homologous structures
analogous structures
vestigial structures
fossil structures
15
Darwin's theory of evolution suggests that
animals that look alike are the most closely related
extinct species are not related
different species can interbreed
species change over time
16
Natural selection acts on
genes
alleles
mutations
phenotypes
17
Natural selection acts on traits that are
heritable
mutated
better
new
18
These tortoises would be better adapted to live in which of the following environments?
areas with short plants and mosses
areas with no plants and sand dunes
areas with only tall trees
areas with lots of taller plants
19
Individuals that are better adapted to their environment will survive and produce
better traits
more offspring
fewer mutations
stronger genes
20
What statement about evolution on the Galapagos finches is true?
mate choice likely plays no role in finch evolution
none of the finch species are reproductively isolated
stabilizing selection favored intermediate beaks
natural selection on beak size is driven by available food
