QUESTION
Clade
Answer:
A group of species that includes an ancestral species and all of its descendants. A clade is
equivalent to a monophyletic group.
QUESTION
Cladogenesis
Answer:
an evolutionary change of a particular species in which new species are branched off from a
common ancestral species.
QUESTION
Convergent evolution
Answer:
the evolution of similar characteristics or features in independent evolutionary lineages
QUESTION
divergent evolution
Answer:
the evolution of different features in independent evolutionary lineages.
QUESTION
Domain
Answer:
a taxonomic group above the kingdom level. The three domains are archaea, bacteria, and
eukarya
,QUESTION
evolution
Answer:
the changes in genetic composition of a population from generation to generation; descent with
modification
QUESTION
genetic drift
Answer:
a process in which chance events cause unpredictable fluctuations in allele frequencies from one
generation to the next. effects of genetic drift are most pronounced in small populations
QUESTION
homoplasy
Answer:
A similar (analogous) structure or molecular sequence that has evolved independently in two
species.
QUESTION
homology
Answer:
Similarity in characteristics resulting from a shared ancestry.
QUESTION
hypothesis
Answer:
a testable explanation for a set of observations based on the available data and guided by
inductive reasoning
QUESTION
natural selection
Answer:
A process in which individuals that have certain inherited traits tend to survive and reproduce at
higher rates than other individuals because of those traits.
, QUESTION
paraphyletic
Answer:
a group of taxa that includes distantly related organisms but does not include their most recent
ancestor
QUESTION
phylogenic tree
Answer:
A branching diagram that represents a hypothesis about the evolutionary history of a group of
organisms.
QUESTION
phylogeny
Answer:
Evolutionary history of a species or group of species.
QUESTION
polyphyletic
Answer:
A group of taxa that includes distantly related organisms but does not include their most recent
common ancestor.
QUESTION
monophyletic
Answer:
A group of taxa that consists of a common ancestor and all of its descendants.
QUESTION
morphology
Answer:
the study of the form of an organism and its structures
QUESTION
taxon
Answer:
a named taxonomic unit at any given level of classification
