Biology 20 Alberta: Evolution ExamQuestions and Answers
What do adaptations result from? - Answers -Gradual change in the characteristics of
members within a population over time
Variation - Answers -A visible or invisible difference that helps an individual survive is
likely to be passed on from survivor to survivor
Genetic Mutation - Answers -May provide an individual with a selective advantage or a
disadvantage, or neither (neutral)
Sexual Reproduction - Answers -Offspring have a combination of genetic material from
both parents (half from mom, half from dad)
What happens if a mutation is beneficial? - Answers -The organism will likely survive
and pass on the mutation (selective advantage)
What happens if a mutation is harmful? - Answers -The organism will likely die and
won't pass on the mutation
Selective Advantage - Answers -The characteristic of an organism that enables it to
survive and reproduce better than other organisms in a population in a given
environment
Selective Disadvantage - Answers -The characteristics of an organism that make it
harder for them to survive and reproduce than other organisms in a population in a
given environment
Bacterial Resistance - Answers -Ability of bacteria to resist antibiotics
Natural Selection - Answers -Process by which a population of organisms changes
because individuals with certain traits can better survive the local environmental
conditions and pass on these traits to their offspring
Artificial Selection - Answers -Process by which a population of organisms changes
because individuals chosen by humans to pass on desirable traits to their offspring
, Scientific Theory - Answers -Explains observations and ties them together in a
comprehensive way, enabling scientists to make predictions about new situations and
experimental outcomes
What did Charles Darwin and Alfred Russel Wallace both develop hypothesis's for? -
Answers -Natural selection
What did Lamarck believe in? - Answers -Spontaneous generation (new species arise
spontaneously from non-living matter)
What did Lamarck believe in with evolution? - Answers -Organisms have a "desire" to
change for the better. Use and/or disuse of structures is passed on to offspring
Example of Lamarcks "Theory": - Answers -Giraffe neck length getting longer from
generation to generation because they stretched to reach the leaves
Lamarckism - Answers -Inheritance of acquired characteristics
When did Charles Darwin travel the world? - Answers -1831-1836
What was the name of the boat Charles Darwin travelled on? - Answers -The HMS
Beagle
What did Charles Darwin do when he was travelling the world? - Answers -Collect data,
specimens, and made observations
What did Charles Darwin discover on his voyage? - Answers -Populations change as
time passes, individuals with physical or behavioural advantages are more likely to
survive and reproduce, competition for resources leads to survival of the fittest (unfit
individuals die), and the theory of natural selection was born
What two major points did Darwin make in his book? - Answers -1. He presented
evidence that the many species of organisms presently inhabiting the earth are
descendants of ancestral species
2. He proposed a mechanism for the evolutionary process, natural selection
Who made the same theory as Charles Darwin at the same time? - Answers -Alfred
Wallace
Carolus Linnaeus - Answers -Founder of taxonomy. Interpreted organismal adaptations
as evidence that the Creator had designed each species for a specific purpose
Theory of Evolution (based off observation) - Answers -1: individuals within any species
exhibit many inherited variations. 2: every generation produces more offspring that can
survive and reproduce. 3: populations of species tend to remain stable in size
