Which process results in greater genetic diversity in offspring?
mutation
recombination of DNA
crossing over during mitosis
inbreeding
3
Organisms with similar structures that come from different taxonomic groups illustrate
convergent evolution
what ancient animals once looked like
what plants once grew in a particular area
what caused the dinosaurs to become extinct
4
the process of adjusting in behavior, physiology, or structure to become more suited to an environment
Adaptation

5
We can learn all of the following things from studying the fossil record except ___.
what the prehistoric climate was like
what caused the dinosaurs to become extinct
what plants once grew in a particular area
what ancient animals once looked like
6
Evidence from embryology supports the theory of evolution by showing that ___.
closely related animal species have similar geographic distributions
closely related organisms have similar stages of development
closely related organisms have more similar DNA and proteins
homologous proteins have arisen separately in many different animal groups
7
Which of the following pairs of terms is not related
evolution - natural selection
analogous structures - bat and butterfly wings
vestigial structures - eyes in a cave-dwelling fish
adaptive radiation - convergent evolution
8
According to the Theory of Evolution by natural selection, which of the following is true?
populations will change over time to better fit their environment
no more offspring are born into a population than can survive
variation does not exist between members of the same species
genetic traits that aid evolution are not passed onto offspring
9
Which of the following is most likely to cause a decrease in a predator population?
fewer prey
predator populations never vary
a reduction in competition
more primary producers
10
What theory explains the origin of chloroplasts and mitochondria in eukaryotic cells.
theory of evolution
theory of natural selection
endosymbiotic theory
cell theory
11
The total number of different alleles present in a population is the ___
genotype
gene flow
gene pool
phenotype
12
Which of the following is the best statement about natural selection?
some in a population have a variation giving an advantage to survive.
most populations of organisms evolve to become more and more alike
if species is isolated from others mutations can occur and decreases change
less variation in a population’s gene pool promotes evolution

Adaptation
Evolution
Extinction
Natural Selection
16

vestigial organs
analogous structures
natural selection
endosymbiosis
