Test Bank For Evolutionary Analysis 5th Edition By Jon C.Herron; Scott Freeman
What supports evolution - ANSWER:patterns of descent with modification
Evolution - ANSWER:genetic change in a population over time
common ancestor - ANSWER:The shared ancestor of new, different species that
arose from one population
Macroevolution - ANSWER:dramatic evolutionary changes (usually morphological)
deriving novel life forms from earlier ones
-think innovative features
-diverging at bigger scale than speciation (living on land versus in water)
evidence of macroevolution - ANSWER:FOSSILS (though record is sparce)
vestigial stuctures
microevolution - ANSWER:small scale changes (changes in gene frequency and trait
distribution that occur within a population or species)
examples of microevolution - ANSWER:1. selective breeding
2. antibiotic resistance
3. plant flowering time
4. vestigial traits
pseudogenes in terms of evolution - ANSWER:vestigial trait (no longer have intron or
promoter)
track time genetically
vestigial traits - ANSWER:Traits that were useful in ancestors that are inherited
today, but that have lost their original use.
speciation - ANSWER:process by which ancestral species give rise to 2 daughter
species
species - ANSWER:populations or groups of populations within and among which
these individuals actually or potentially interbreed outside of which they do not
interbreed
lab experiments - ANSWER:1. species of Pseudomonas syringae cannot infecct wild
type species
2. fruit flies adapt to different diets doesn't lead to new species but difference in
mating preferences
, partial reproductive isolation - ANSWER:hybrid fertility or viability lower, but not 0
speciation stages - ANSWER:1. variation exists
2. subpopulations form
3. distinct populations
4. reproductive isolation
(5. maybe ring species)
ring species - ANSWER:evidence that one species can split into two (all 4 stages in
continuous loop)
Evidence from the fossil record - ANSWER:1. The Fact of Extinction
2. The Law of Succession
3. Transitional Forms
fact of extinction - ANSWER:vast majority of species have been lost to extinction
transitional forms - ANSWER:fossils that connect ancestral species with their
descendants through a series of tiny steps
law of succession - ANSWER:extinct species in the fossil record were succeeded in
the same region by similar species
common ancestry is supported by - ANSWER:genetics, anatomical similarities
(homology)
homology - ANSWER:similarity resulting from common ancestry
nested patterns of traits - ANSWER:used in phylogenetic trees
-functional similarity does not necessarily indicate common ancestry
convergent evolution - ANSWER:environmental pressures shape genes- homoplasy
homoplasy - ANSWER:A similar (analogous) structure or molecular sequence that has
evolved independently in two species.
individual molecular homologies - ANSWER:-shared genetic code/flaws
-down to nucleotides
pseudogenes - ANSWER:extracopy of functional genes
-find shared pseudogenes
universal molecular homologies - ANSWER:genetic code
genetic code - ANSWER:all organisms use same nucleotides
