In the Galápagos islands today, many species of finch can be found. Each population on each different island has different adaptations that help them survive. Who postulated that all of these varieties likely arose from a single common ancestor?
Isaac Newton
James Watson
Rosalind Frank
Charles Darwin
When organisms experience environmental pressures from predators, amount of food, amount of water, etc., what process will cause the population to change over time?
Random mating
Natural Selection
A large population size
Gene flow
In the Galápagos Islands, different birds have different beak sizes and therefore eat different foods. This is an example of
adaptation
extinction
evolution
gene flow
In the phrase "survival of the fittest" what does the word "fittest" mean?
None of these represent the word "fittest" in the phrase "survival of the fittest"
The smartest organism that can learn the easiest way to get food
The best adapted organism that is able to reproduce successfully
The strongest organism that can swim the fastest.
Cheetahs that can run fast and catch prey are able to survive and reproduce successfully. Slower cheetahs don't catch as much prey and they die before they are able to reproduce. This is an example of
Natural selection
Extinction
Competition
Symbiosis
When a large population shrinks and then grows again, the gene pool also shrinks. The organisms that come after this event will have less genetic variety. This form of genetic drift is called the
founder effect
bottleneck effect
population transition effect
gene flow effect
A group of individuals are stranded on a deserted island and never rescued. They begin a new civilization that lasts for thousands of years. This type of genetic drift is called the
founder effect
bottleneck effect
population transition effect
gene flow effect
Natural selection is one of the agents of genetic change in a population. Natural selection happens when there is already (a) within a population and environmental pressures cause organisms to either die before reproducing or live long enough to (b) . The other agents of evolutionary change include a (c) population size, non-random mating, (d) , and (e) or movement.
Early cells on earth would have been
extremely large
eukaryotic
prokaryotic
photosynthetic
A change in the gene pool of a population can allow for future organisms to gain a helpful adaptation. This change is most likely to arise from
a single mutation that is passed on to future generations.
an organism willing itself to live.
an organism learning how to use a tool.
macroevolution.
