QUESTIONS AND VERIFIED ANSWERS

GRADED A+
QUESTIONS AND ANSWERS
Evolution. ANSWER - changes in DNA of a species over time
Natural Selection. ANSWER - The environment selects which individuals produce
the most.
Artificial Selection. ANSWER - When humans decide which individuals will breed
Adaptation. ANSWER - A change in protein synthesis giving an advantage to an
organism but not a change in DNA
vestigial structures. ANSWER - A structure in an organism that has lost all or most
of its original function.
Gene pool. ANSWER - The total collection of alleles in a population
Convergent Evolution. ANSWER - the evolution of similar traits in distantly related
species eg. whales and sharks
Divergent Evolution. ANSWER - evolution of one or more closely related species
into different species; resulting from adaptations to different environmental
conditions.
Coevolution. ANSWER - process in which two or more species evolve in response to
changes in each other
Eg. agouti and brazil nut
, Lamarck. ANSWER - inheritance of acquired characteristics- proved incorrect
Galapagos Islands. ANSWER - Islands where Darwin notice adaptive radiation
Cuvier. ANSWER - a palaeontologist who proposed the theory of catastrophism
Lyell. ANSWER - a geologist who proposed the theory of uniformism
Macroevolution. ANSWER - large scale evolutionary changes including the
formation of new species
Microevolution. ANSWER - Small changes in gene frequencies within one
generation of a population/species.
Speciation. ANSWER - the formation of a new species
Genetic Drift. ANSWER - changes to an allele's frequency as a result of chance; such
changes are more pronounced in small populations
Gene Pool. ANSWER - All of the alleles in all the individuals that make up a
population
Alleles. ANSWER - a specific form of a gene
Mutation. ANSWER - A change in DNA
homologous structures. ANSWER - common ancestor - structures made of similar
material but used for a different function.
Disruptive Selection. ANSWER - a type of natural selection in which two extreme
forms of a trait are selected
