Biology 1407 Test questions and
answers graded A+
Evolution - ANS✅✅The phenomena that populations of organisms change over the course of
many generations. As a result, some organisms become more successful at survival and reproduction
Microevolution - ANS✅✅Changes in a population's gene pool from generation to generation
Macroevolution - ANS✅✅Evolutionary changes that create new species and groups of species
Species - ANS✅✅A group of related organisms that share a distinctive form in nature and (for
sexually reproducing species) are capable of interbreeding
Population - ANS✅✅A group of individuals of the same species that occupy the same environment
and can interbreed with one another
Molecular Evolution - ANS✅✅The molecular changes in genetic material that underlie the
phenotypic changes associated with evolution
Empirical Thought - ANS✅✅Thought that relies on observation to form an idea or hypothesis,
rather than trying to understand life from a nonphysical or spiritual point of view
Inheritance of Acquired Characteristics - ANS✅✅Jean-Baptiste Lamarck's incorrect hypothesis that
species change over the course of many generations by adapting to new environments
Natural Selection - ANS✅✅The process that eliminates those individuals that are less likely to
survive and reproduce in a particular environment, while allowing other individuals with traits that
confer greater reproductive success to increase in numbers
Transitional form - ANS✅✅An organism that provides a link between earlier and later forms in
evolution
Biogeography - ANS✅✅The study of the geographic distribution of extinct and modern species
