What is the importance of the Galapagos islands to Darwin? - ANS✅✅its where he collected all of
his specimens and made numerous observations
Know the influence of Lyell, hooker, and gray on Darwin - ANS✅✅Charles Lyell: famous geologist
who Darwin modeled his research after
Hooker: First accredited scientist to publicly back Darwin.
Asa Gray: A botanist, Darwin wrote to him outlining his theory of evolution
What is the Malthusian theory? How did it influence Darwin and Wallace? - ANS✅✅the idea that a
population tends to grow faster than the subsistence needed to sustain it. It caused them to rethink
their idea which brought them to the idea of natural selection and thus limiting population growth.
Who was Alfred R Wallace and what did he propose to Darwin? - ANS✅✅Naturalist who visited

Beagle - 1839
Origin of Species - 1859
In Darwin's premises of evolution what is meant by inheritable variation and which variations have
the most effect on evolutionary changes in the population? - ANS✅✅Inheritable variation-
characteristics vary in a population. it is the accumulation of all of the variations in the gene pool
that affect the population
What characteristic of population results in competition for resources between individuals? -
ANS✅✅Overpopulation often results in competition for natural resources
What does a potential growth curve look like? - ANS✅✅a J-shaped curve
What does a normal growth curve look like? - ANS✅✅An S-Shaped curve
What is the significance of environmental resistance on a population? - ANS✅✅It limits the growth
of the population
What is natural selection? - ANS✅✅The idea that the fittest survive and pass along their traits to
their offspring.
What is meant by survival of the fittest? - ANS✅✅the fit survive to reproduce
What is the significance of the Galapagos Islands? - ANS✅✅The Galapagos Islands are the place
Darwin noticed the adaptability and variations within animal species.
