1. What are some definitions of evolution?: - a biological change that ocurs over generations
- the mutability of the DNA molecule that enables life to change over generations
- Decent with modification from a common ancestor
2. Which definition from evolution do you prefer?: - Biological change that occurs over
generations
- andthe mutablity of the DNA moleculel that enables life to change over generations because
sometimes the phenotype doesn't show the process of evolution that has occured.
3. What evidence shows that life has changed over generations?: - Fossil record,
- SELECTIVE BREEDING OF ANIMALS/PLANTS
4. Which biological molecule endows biological sytems with an intrinsic abil- ity to change over
generations?: DNA
5. Which property of DNA molecule enables biological change over genera- tions?: Mutablity
6. Does the mutability of this the RNA genome of the coronavirus & influenza viruses enable the
evolution of anti-viral drug resistance?: Yes
7. how will an improved understanding Evolution understanding of evolution cause for
improvements in agriculture?: - increased yeilds
-reduced diesease/prest damage
8. how will an improved understanding of Evolution cause improvements in medicine?: -infectious
disease management
- reduced pathogen virulence
-reduce rate of antibiotic resistance evolution in bacteria
9. how will an improved understanding of Evolution cause improvements in public health?: -
infectious disease management
- reduced pathogen virulence
-reduce rate of antibiotic resistance evolution in bacteria
10.Why is the medical community concerned about the evolution of antibiotic resistance in
pathogenic bacteria?: eventually they will become drug resistant bacteria. Cannot cure at the
rate they are capable of reproducing.
11.Why is the medical community concerned about the evolution of fungicide resistance in
pathogenic fungi?: can't treat patients with infections due to patho- genic fungi

12.Why is the medical community concerned about the evolution of Quinine and artemisinin?:
could increase Malaria
13.define adaptation: a trait that increases reproduction
14.define allele: an alternative form of a single gene
15.define genotype: the two alleles that a individual has FOR a specific gene
16.define phenotype: an individuals observable anatomical, physiological, and behavioral
characteristics
17.define population: individuals of the same species that inhabit a specific loca- tion at a
specific time
18.define species: (a type or kind of life form) q group of populations whose members
can reproduce with one another to produce fertile offspring
19.define trait: a characteristic inherited from a parent
20.How is Evolution by Natural Selection affecting agriculture?: It is making pests AND
PATHOGENS resistant to pesticides AND ANTI-MICROBIAL COM- POUNDS
21.How is Evolution by Natural Selection affecting medicine?: -It is creating antibiotic-resistant
bacteria, DRUG-RESISTANT VIRUSES, PROTOZOA, FUNGI & PERHAPS DRUG-RESISTANT
PARASITIC WORMS
-IT ELIMINATES THE ARRAY OF ANTI-MICROBIAL DRUGS THAT CAN BE USED TO TREAT INFECTED
PATIENTS EFFECTIVELY.
22.Describe how Natural Selection increases the frequency of Antibiotic-re- sistant bacteria in
bacterial populations exposed to antibiotics.: Over time there will be more antibiotic-resistant
bacteria in the population
23.Describe how Natural Selection increases the frequency of Antiviral drug-resistant viruses in
viral populations exposed to antiviral drugs.: It will increase the drug-resistant viruses
24.Describe how Natural Selection increases the frequency of Quinine-re- sistant Plasmodium
falciparum in populations exposed to Quinine: Increases THE PROPORTION OF PATHOGENS
RESISTANT TO QUININE.
25.Describe how Natural Selection increases the frequency of Insecticide-re- sistant insects in crop
pest populations exposed to insecticides.: Increases THE PROPORTION OF CROP-EATING INSECTS
RESISTANT INSECTICIDES.
26.Which policies would you recommend to reduce the rate of Antibiotic-re- sistance in Bacteria
evolving by natural selection?: first determine if they are becoming resistant to NATURAL or
man-made antibiotics. Then determine if the doctors need to limit the amount of antibiotics
they prescribe. ONLY PRESCRIBE ANTIBIOTICS TO PATIENTS WITH BACTERIAL INFECTIONS.
