Total questions: 19
Worksheet time: 12mins
The hypothesis that evolution occurs at a rapid pace, separated by periods of no change,
was supported by Darwin
is known as punctuated equilibrium
is supported by many transitional forms in the fossil record
was proposed by Lyell
The number of individuals that possess favorable characteristics will increase in a population
(a)
The evolution of beak sizes in Galapagos finches is a response to...
how finches use their beaks
what type of seed is availble
whether the populations interbreed
the nutritional content of the seeds
According to Darwin, evolution occurs...
in response to use or disuse of a characteristic
by punctuated equilibrium
by natural selection
in an individuals timeline
Natural selection causes...
changes in the environment
plants and animals to produce more offspring than can survive
changes in the frequency of certain alleles in a population
all of the above
The traits of individuals best adapted to survive become more common in each generation because...
offspring without those traits do not survive
the alleles responsible for those traits increase through natural selection
those individuals do not breed
natural selection does not effect well adapted individuals
The process of species changing slowly and consistently
(a)
In the study of the bacteria that cause tuberculosis, scientists have learned that...
the bacteria have become more sensitive to antibiotics due to evolution
patients are allergic to antibiotic treatment
the bacteria have become resistant to antibiotics due to natural selection
patients frequently die from antibiotic treatment
Natural selection is the process by which...
the age of Earth is calculated
organisms with traits well suited to the environment survive
acquired traits are passed from one generation to the next
all of the above
Similar bone structures between species is known as...
vestigial structures
divergent structures
homologous structures
embryonic structures
Human populations do not grow uncheck because of war, disease, and famine
(a)
The theory of evolution predicts that...
closely related species will show similarities in nucleotide sequences
if species have changed over time, then their genes should have changed
closely related species will show similarities in amino acid sequences
all of the above
Organisms that produce more offspring than their environment can support and that they compete with one another to survive are...
elements of natural selection
not elements of evolution
the only mechanisms of evolution
the beginning of speciation
Structures that are present in an organism, but reduced in size and have little to no function are called...
pharyngeal pouches
vestigial structures
convergent structures
embryological homologies
Species change in spurts, with vast amounts of time in between
(a)
Strong evidence for evolution comes from...
forensic biology
phylogenetic trees
works of philosophy
the fossil record
Darwin theorized that natural selection is...
the mechanism of evolution
how modern species have come to exist
the explanation for beak variation in finches
all of the above
Species change over time, or descent with modification
(a)
Similarities in structures suggest that organisms...
have a common ancestor
all grow at different rates
evolved slowly
lived for a long time
