Biology 20 Alberta: Evolution Final Exam
Questions Fully Solved.
What do adaptations result from? - Answer Gradual change in the characteristics of members
within a population over time
Variation - Answer A visible or invisible difference that helps an individual survive is likely to be
passed on from survivor to survivor
Genetic Mutation - Answer May provide an individual with a selective advantage or a
disadvantage, or neither (neutral)
Sexual Reproduction - Answer Offspring have a combination of genetic material from both
parents (half from mom, half from dad)
What happens if a mutation is beneficial? - Answer The organism will likely survive and pass
on the mutation (selective advantage)
What happens if a mutation is harmful? - Answer The organism will likely die and won't pass
on the mutation
Selective Advantage - Answer 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 - Answer 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 - Answer Ability of bacteria to resist antibiotics
Natural Selection - Answer 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 - Answer Process by which a population of organisms changes because
, What did Charles Darwin and Alfred Russel Wallace both develop hypothesis's for? - Answer
Natural selection
What did Lamarck believe in? - Answer Spontaneous generation (new species arise
spontaneously from non-living matter)
What did Lamarck believe in with evolution? - Answer Organisms have a "desire" to change for
the better. Use and/or disuse of structures is passed on to offspring
Example of Lamarcks "Theory": - Answer Giraffe neck length getting longer from generation to
generation because they stretched to reach the leaves
Lamarckism - Answer Inheritance of acquired characteristics
What two major points did Darwin make in his book? - Answer 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? - Answer Alfred Wallace
Evidence of Evolution - Answer 1. Palaeontology (study of fossils)
2. Biogeography (study of distribution of species)
3. Anatomy (study of organisms physical structures)
4. Embryology (study of fetal development)
5. Molecular Biology
6. Genetics
Paleontology - Answer Study of fossils
Biogeography - Answer Study of distribution of species
