BIOL 171 Final Exam || with 100% Errorless Solutions.
Evolution is a theory that can be applied to different species, but cannot be directly tested correct
answers False
Several scientific studies have reported results that reject the process of evolution correct
answers False
Two species of birds that are closely related have evolved from an extinct common ancestor
correct answers True
Crab and human share common ancestor correct answers True
Evolution often produces species that appear to have imperfect characteristics correct answers
false
Evolution correct answers a mechanism that explains how species change over time
closest living ancestors to humans correct answers chimpanzees and bonobos
Adaptive organisms correct answers organisms are adopted to environment in which they live
adaptation correct answers a heritable trait or behavior that aids the survival and reproduction of
an organism in its present environment
species correct answers a group of individuals organisms that interbreed and produce fertile,
viable offspring
population correct answers a group of individual that share a gene pool and includes individuals
natural selection correct answers individuals that have certain inherited traits tend to survive and
reproduce at higher rates than individual that don't
How thought of Natural Selection? correct answers Darwin and his finches
The Biological Species Concept correct answers Developed by Enerst Mayr
a species is a group of organisms that can interbreed into nature and produce viable fertile off
spring
morphlogical species concept correct answers fossil species identification
phylogenetic species concept correct answers asexual species identification relies on genetics
different and morphology
How do species form? correct answers through speciation
, Speciation correct answers the formation of species from one original species
Speciation requirements correct answers barrire to gene flow
Evolution (via natural selection) that leads to reproductive isolation
Natural Selection Observation 1 correct answers Members of a population vary in their inherited
traits
Natural Selection Observation 2 correct answers All species can produce more offspring than
their environment can support and many of these offspring fail to survive and reproduce
After speciation occurs, what do we call the original species? correct answers Ancestor species
Barriers that can lead to speciation correct answers Allopatric and sympatric
Allopatric Speciation correct answers geographic barrier that reduces gene flow
Sympatric Speciation correct answers subset of population acquires differences
What does speciation happen through? correct answers it happens through polyploidy
Polyploidy correct answers condition where organism have more than two paired sets of
chromosomes
Autopolyploidy correct answers one species involved in generating a polyploid
Allopolyploidy correct answers two species involved in generating polyploid
Type of Reproductive Isolation correct answers Pre-zygotic and post-zygotic isolation
pre-zygotic isolation correct answers mechanisms that prevent mating or hinger fertilization
before mating occurs
post-zygotic isolation correct answers mechanisms that prevent a hybrid zygote from developing
into a viable, fertile adult (acting after mating occurs)
Type of Pre-Zygotic isolation correct answers habitat, temporal, behavioral, mechanical,
habitat isolation correct answers species occupy different habitats, never come into contact
temporal isolation correct answers breed during different times, not fertile during same period
during year
behavioral isolation correct answers individuals do not recognize each other as potential mates
(firefly flashing patterns, peacock feathers flashing)
