BIOLOGY 106 EXAM 1: EVOLUTION
QUESTIONS WITH CORRECT
ANSWERS!!
Evolution - ANSWERChange in allele frequency (of a population) over time
Biological Populations - ANSWERGroups of individuals of the same species that are
subdivided from other populations by geography
Adaptation - ANSWERPopulation's characteristics change to make its members
better suited to an environment -- A trait that increases the fitness of an individual in
a particular environment (Only occurs when a POPULATION changes in response to
natural selection) (Every __________ is a compromise)
Fitness - ANSWERThe ability of an individual to produce offspring.
(Individuals with high _______ produce many surviving offspring)
Acclimation - ANSWEROccurs when an INDIVIDUAL changes in response to
changes in the environment
Chemical Evolution Hypothesis - ANSWERExplains how complex carbon-containing
compounds (and eventually life) could have formed from simpler molecules
Species - ANSWERGroup of related organisms that share a distinctive form
Populations - ANSWERGroup of individuals of the same species that can interbreed
with one another
Gene Pool - ANSWERAll of the genes in a population
Variation - ANSWERInfluenced by both the biotic and abiotic
Biotic Interactions - ANSWERHabitat, Food-getting, Mating finding, Protection,
Communication, and Competition are all what?
Abiotic Environmental Changes - ANSWERClimate/temperature, Atmosphere, Land
masses, Flood, Glaciation, Volcanic eruptions, and Meteoric impacts are all what?
Descent with Modification - ANSWERChange over time produced modern species
from ancestral species
Natural Selection - ANSWERCuts out those individuals less likely to survive and
reproduce while allowing others with traits that make them better suited to survive
and reproduce
