Alfred Russel Wallace
Charles Darwin
Jean Baptiste Lamarck
Thomas Malthus
While on the Beagle, Darwin's observations included

fossils of gigantic living mammals.
rocks containing mountain fossil found in the sea.
all of these.
Charles Lyell____________
argued that Earth must be far older than most people believed.
said that human populations grow faster than their resources.
developed the idea of the inheritance of acquired characteristics.
none of the above.
The inheritance of acquired characteristics states that _________
traits an organism develops during its own lifetime are determined by nature
traits an organism develops during its own lifetime are not passed to offspring
traits an organism develops during its own lifetime are passed on to offspring
traits an organism develops during its own lifetime are determined by evolution
Artificial selection_______
occurs naturally in pigeons
is based in the inheritance of acquired characteristics
is when nature selects for beneficial traits
is when humans select from beneficial traits
The Galapagos Islands ___________
differ from on another in important ways
are where Darwin made some of his most important observations
each have some distinct plant and animal life
all of the above
Darwin's reasoning included which of the following?
Darwin assumed that species can change over time
Darwin knew that resources could grow faster than populations
Darwin inferred that artificial selection could change species over time
all of the above
The Galapagos tortoises _________
evolved as the Galapagos islands separated from each other
are able to swim between islands to eat any available food
have differently shaped shells depending on which island they inhabit
all of the above
Jean Baptiste Lamarck ___________
