A change in the genetic makeup of a population over time is called:
Mutation
Adaptation
Evolution
Natural selection
Which of these is a random process in evolution?
Natural selection
Genetic drift
Adaptation
Speciation
The process by which organisms better suited to their environment survive and reproduce is called:
Mutation
Natural selection
Genetic drift
Migration
Darwin's finches on the Galapagos Islands are an example of adaptive radiation. This means they:
Migrated from different locations and adapted to the same environment.
Developed similar traits due to similar environmental pressures.
Evolved from a common ancestor and diversified to fill different ecological niches.
Lost their ability to adapt over time due to limited resources.
Which of the following is a key factor driving adaptive radiation?
Lack of competition.
Stable environmental conditions.
Availability of new ecological niches.
Low mutation rates.
Adaptive radiation is characterized by:
Slow and gradual changes over long periods.
Convergence of different species towards similar traits.
Rapid diversification from a common ancestor.
Extinction of a large number of species.
The Australian marsupials are a good example of:
Convergent evolution.
Adaptive radiation.
Coevolution.
Parallel evolution.
