Mechanics of Evolution
Sources of Variation
Results of Genetic Variation
Patterns of Change
100
a collection of fossils that provides clues to the history of earths organisms.
What is a fossil record?
100
indicate that the process of evolution was controlled by "nature" rather than by people
What is natural selection?
100
a change in the base sequence of a DNA molecule.
What is mutation?
100
the structure of any organism is the result of its species' entire evolutionary history.
What is structural changes??
100
changes in a species are often related to
What is environmental change
200
the billions of years of earths history.
What is geologic time
200
supply of resources needed for life.
What is finite
200
the modern theory of evolution states that a basis for variation within a species.
What is mutations?
200
molecular or biochemical changes effect how an organism works.
What is functional change?
200
the disappearance of an entire species
What is extinction
300
consept that has been tested and confirmed in many different ways and can be used by scientists to make predictions about the natural world.
What is a theory
300
the potential for species to increase its numbers.
What is overproduction
300
the sorting and random recombining of genes during meiosis and fertilization results in new and different combinations of genes.
What is genetic shuffling
300
a broad range of activities and approaches which focus on the individual, community, and environmental influences on behavior
What is behavioral change?
300
peoples interference with nature
What is the one factor witch has probably been the chief cause of the extinction of various species?
400
change in species over long periods of time.
What is the process of evolution?
400
the unique combination of traits each organism inherits from its parents.
What is genetic variation?
500
describe past environments in the history of life
What does the study of fossils allow scientist to do
500
any trait that helps an organism survive and reproduce under a given set of environmental conditions.
What is adaptive value?
500
the best scientific explanation for differences in structure, function, and behavior found in different species of organisms.
