Greater reproductive success.
Increase in size.
Which statement below best describes the
relationship between natural selection and
adaptation?
Natural selection and adaptation describe how
animals change.
Natural selection describes how organisms
change and adaptation explains why.
Natural selection is the opposite force of
adaptation in the environment.
Organisms undergo adaptive evolution in
response to natural selection.
A certain species of bird that feeds on seeds lives
on a remote island. Many young birds have
recently been born with shorter beaks that can
crush the seeds more quickly. Which factor is
most likely responsible for this adaptation?
A decrease in competition for shelter.
A decrease in temperature.
An increase in competition for food.
An increase in predators.
Organisms are constantly adapting for what:
They may have a variety of food resources.
Be better able to survive and reproduce in their
environment.
They can expand their population to new areas.
They can expel other competitive species from
their environment.
Mention three evidences that support the validity of the theory of evolution:
