Alfred Russel Wallace
Charles Darwin
Jean Baptiste Lamarck
Thomas Malthus
While on the Beagle, Darwin's observations included
rock ledges that had clearly once been beaches.
fossils of gigantic living mammals.
rocks containing mountain fossil found in the sea.
all of the above.
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
(Lamarck)
traits an organism develops during its own lifetime are determined by nature.
traits an organism develops during its own lifetime are not passed on 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 on the inheritance of acquired characteristics.
is when nature selects for beneficial traits.
is when humans select form beneficial traits.
The Galápagos Islands
differ from one another in important ways.
are where Darwin made some of his most important discoveries.
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 all of the above
The Galápagos tortoises
evolved as the Galápagos 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
was one of the first scientists to propose that species evolve over time.
developed a widely accepted theory of evolution.
determined that Earth must be far older than most people believed.
said that famine and disease keep populations in check by killing off their weakest members.
Darwin’s theory explains
why some organisms have better fitness than others.
why species face a struggle for existence.
why giraffes have such long necks.
all of the above.
The work of Lamarck motivated Darwin to finish his work.

True
False
Fitness refers to an organism’s relative ability to survive and produce fertile offspring.
True
False
It took Darwin over 20 years to compile his findings, develop his theory, and publish his book.
True
False
Lamarck convinced Darwin that populations could grow faster than their resources.
True
False
Artificial selection is when nature chooses the traits beneficial for survival.
True
False

True
False
Darwin determined that man selects the variations among organisms that are most useful for survival.
True
False
The theory of evolution by Natural Selection states that living things with beneficial traits produce more offspring than others do.
