1. Which scientist formulated the theory of evolution through natural selection?
Charles Darwin
Thomas Malthus
James Hutton
Jean-Baptiste Lamarck
1. Lamarck’s ideas about evolution were wrong because he proposed that
species change over time
species descended from other species
acquired characteristics can be inherited
species are adapted to their environments
1. Lyell’s Principles of Geology influenced Darwin because it explained how
organisms change over time
adaptations occur
the surface of Earth changes over time
the Galápagos Islands formed
1. A farmer’s use of the best livestock for breeding is an example of

artificial selection
extinction
adaptation
The ability of an individual organism to survive and reproduce in its natural environment is called

Which of the following is an important concept in Darwin’s theory of evolution by natural selection?
descent with modification
homologous molecules
processes that change the surface of Earth
the tendency toward perfection
1. Which of the following does NOT provide evidence for evolution?
fossil record
natural variation within a species
geographical distribution of living things
homologous structures of living organisms
1. DNA and RNA provide evidence of evolution because
all organisms have nearly identical DNA and RNA
no two organisms have exactly the same DNA
each RNA codon specifies just one amino acid
in most organisms, the same codons specify the same amino acids.
1. A bird’s wings are homologous to a(n)
fish’s tailfin

mosquito’s wings
1. What process produced the two different types of beaks shown?

natural selection
geographical distribution
