A group of small islands near the equator, about 1000 km off the west coast of South America. Observations of the island fauna lead to the Theory of Evolution by Natural Selection.
A body structure in a present day organism that no longer serves its original purpose
The human appendix is an example
All of the above
A British naturalist who proposed a similar theory of evolution but did not get much credit for his work.
Alfred Russell Wallace
Jean Baptiste Lamarck
A mechanism for change in populations where an organism with a favorable trait survives, reproduces, and pass the favorable phenotype to the next generation. Organisms without the favorable phenotype are less likley to survive and reproduce.

The enviroment around Manchester, England changed during the Industrial Revolution. How did this change affect peppered moths living in the area?
Natural selection favored moths with dark wings because predators could not see them on the soot-colored trees.
Natural selection favored moths with white wings that were easy for predators to see.

very similar DNA sequence
exactly the same DNA sequences
no proteins in common
completlely different DNA sequence
Inherited trait that helps an organism survive is a(n)
Why are advantageous traits more likley to be passed onto offspring?
Because they are more likley to survive and reproduce
Because they come from dominent alleles
Because they come from recessive alleles
Because the trait is an acquired phenotype
The ability of an organism to survive and reproduce in its specific enviroment
