variations
mutations
selective breeding
adaptations
2
Who proposed the theory that evolution happens as a result of natural selection?
James Watson
Gregor Mendel
Charles Darwin
Rosalind Franklin
3
What is it called when all of the organisms of a species completely die out?
adaptation
variation
artificial selection
extinction
4
Bottleneck Effect
Genetic drift results from an event that reduces the size of a population
Genetic drift occurs after a group of individuals colonize a new area
Isolation due to differences in courtship or mating behavior
finding the age of a fossil, comparing its place to fossils in other layers
5
What does this bird use its beak for?
to crush seeds
to sip nectar
to get insects out of small crevices
6
Which one cannot be used as evidence to support the theory of evolution?
Anatomical similarities across species
Genetic information
Species specific list of habitats
Developmental commonalities across species
7
Founder Effect
Remnants of an organ or structure that functioned in an earlier ancestor
Evolution of two or more species from one ancestral species
Collection of alleles found in all of the individuals of a population
Genetic drift occurs when a small number of individuals colonize a new area
8
What is the purpose of this cuttlefish's adaptation?
It enables the cuttlefish to survive.
It a an inheritable mutation.
It is a source of genetic variation.
9
The preserved remains or physical evidence of an organism that lived in the past are called —
fossils
mutations
variations
adaptations
10
What does this bird most likely use its beak for?
the eat seeds
to eat insects out of crevices
to use probes to eat insects
11
Two birds began to live in different environments. What would cause changes in feather color?
extinctions
mutations
variations
clones
12
genetic drift
The exchange of genes with another population.
The collection of fossils recorded in rock layers over time.
A change in a gene pool due to chance.
Preserved remains or markings left by organisms that lived in the past.
13
What does this bird use its beak for?
to crush seeds
to use a probe to get insects
to sip nectar from skinny flowers
14
Scientists believe homologous structures are biologically similar. These similarities suggests-
these animals share a common ancestor
these animals must live together
these animals were born around the same time
these animals are all mammals
15
What do we can the timeline of earth scientists have developed by studying fossils?
carbon records
fossil record
radiometric dating
theory of evolution
16
What is a genetic difference in a species that is not harmful or beneficial?
natural selection
variation
artificial selection
adaptation
17
What is a genetic difference that is beneficial to the survival of a species?
artificial selection
adaptation
variation
natural selection
18

variations
Cloning
replications
mutations
19
What does this bird use its beak for?
To get insects out of small crevices

To crush seeds
20
What most likely caused the finches on the Galapagos Islands to have different beaks?
different types of predators
different types of food
different types of eggs
different types of nests
21
What are mistakes or changes that occur in the DNA sequence?
extinction
transcription
evolution
mutation
22
When organisms are better adapted to their environment they will survive and reproduce better.
natural selection
variation
artificial selction
adaptation
23
Which sources of data cannot be used as evidence for evolution?
