Quiz Evolution

Name:

Evolution

True/False Indicate whether the sentence or statement is true or false.
	1.	The theory of evolution states that species change over time.
	2.	The inheritance of acquired characteristics was one mechanism of evolution supported by Darwin.
	3.	Darwin observed that the plants and animals of the Galapagos Islands were the same as those on islands off the coast of Africa with similar environments.
	4.	The book Principles of Geology by Charles Lyell described how changes in land formations can cause species to evolve.
	5.	In his “Essay on the Principle of Population,” Malthus said humans were the only population that could continue to grow in size indefinitely.
	6.	The two major ideas that Darwin presented in The Origin of Species were that evolution occurred and that natural selection was its mechanism.
	7.	The environment dictates only the direction and extent of evolution.
	8.	The environment selects which organisms will survive and reproduce by presenting challenges that only individuals with particular traits can meet.
	9.	The way an embryo develops is not important in determining the evolutionary history of a species.
	10.	Within populations, divergence leads to new species.
Completion Complete each sentence or statement.
	11.	When an organism becomes ____________________, the tissues are replaced by harder minerals.
	12.	A species that has disappeared permanently is said to be ____________________.
	13.	A change in species over time is called ____________________.
	14.	The process by which organisms with traits well suited to an environment survive and reproduce at a greater rate than organisms less suited for that environment is called ____________________.
	15.	According to Darwin, the ____________________ determines the rate at which organisms survive and reproduce.
	16.	A(n) ____________________ consists of all the individuals of a particular species in a particular place.
	17.	Homologous structures are similar because they originated in a shared ____________________.
	18.	____________________ structures are similar because they originated in a shared ancestor.
	19.	Closely related species show more ____________________ in nucleotide sequences than distantly related species.
	20.	____________________ occurs as two or more species change in response to each other.
