Answers
1
The MOST accurate way to determine the evolutionary relationship between two animals
common behaviors
similar physical features
Fossils
DNA or Proteins
2
the sudden, abrupt appearance of a species from a common ancestor indicates which theory of evolution
macroevolution
gradualism
microevolution
punctuated equilibrium
3
Which organisms are BEST able to survive in nature?
best suited to their environment
greatest number of mutations
best camouflage
acquired characteristics over their lifetime
4
What is the most supportive evidence showing different species being related?
fossils records
Embryology
Homologous Structures
Molecular (DNA)Evidence
5
When a small group of individuals leave a larger population and genetic variation is reduced due to chance.
allopatric speciation
geographic isolation
founder effect
gene flow
6
Whats the best explanation for Darwins finches beak shape?
they changed to eat different foods in their lifetime
they were a result of natural selection
7
How do bacteria become antibiotic resistant?
the bacteria that survive antibiotics reproduce
The individual bacteria change their genetic makeup
8
How do fossils help scientists classify organisms?
predict the next species
help determine closest living relative
help determine when traits evolved
construct pedigrees
9
Organisms that look similar, but are not close relatives show which type of evolutionary pattern?
convergent
divergent
homologous
vestigial
10
What does this picture represent
analagous structures
vestigial structures
common ancestry
idk what those are
11
Embryology of these 4 animals suggest all EXCEPT
few differences in early development
common features like gills in all the embryos
common ancestry
no similarities
12
similar structures shared by different species
homologous structures
integrated structures
vestigial structures
gradual structures
13
What is gene flow?
transfer of genes from one population to another
strongest organisms survive
movement of genes within a population
individual genetic variability
14
humans share about 98% of their DNA code with chimpanzees, what does this suggest?
they evolved at the same time
they evolved with from each other
their evolution in nearly complete
they evolved from a common ancestor
15
structures that look different on the outside but are actually similar in structure on the inside
analagous structures
homologous structures
vestigial structures
common structures
16
What is punctuated equilibrium?
when an organism rapidly evolves traits
when an organism slowly evolves
17
The leg bones of whales are considered ___________ structures.
homologous
evolutionary
vestigial
analagous
18
Original population of rabbits is white, lack of snow produces a higher number of gray rabbits, what has happened?
they decided to change color
gray is dominant over white
habitat changed making white rabbits easy to see.
genetic mutations
19
two species evolving together
convergent evolution
divergent evolution
coevolution.
Larmackian theory
20
How does embryology support the theory of evolution
suggests a common ancestor
suggest different ancestors
