bio 182 unit 6 : Evolution Population Questions and Answers
with Solutions UPDATED!!!
evolution - ANSWER heritable changes in characteristics of a
population from one generation to the next.
what lead to the descent with modification - ANSWER genetic
variation and natural selection
genetic variation - ANSWER individuals have varying traits, traits
are heritable, and variation is due to mutations
natural selection - ANSWER more offspring produced than will
survive, heritable traits make them more suited to
environment, survivors are selected by nature
evidence for evolutionary changes - ANSWER studies of natural
selection, fossil record, biogeography, convergent evolution,
selective breeding, and genetic information.
homologies - ANSWER a similarity that occurs due to the
descent from a common ancestor
, 2|Page
homologies - ANSWER include anatomical, developmental,
molecular
fossil record - ANSWER fossils compared according to age
(oldest to youngest) morphological changes are apparent
transitional form - ANSWER intermediate state between
ancestral form and form of descendants
biogeography - ANSWER study of geographic distribution of
species
-islands are isolated habitats, geography has played a key role in
evolution of new species
endemic - ANSWER plants and animals that are naturally found
in a particular location
ex. island fox, endemic to channel islands
