Why explain the theory of evolution, which documents the change in the genetic makeup of a biological population over time?
The theory of evolution began as a revolutionary idea, but it remains central to the study of biology. Evolution is the unifying concept in biology. This theory documents the change in the genetic makeup of a biological population over time. Evolution helps us understand the development of antibiotic resistance in bacteria and other parasitic organisms. The following are just a few of the antibiotic resistant “bugs” plaguing humans.
- Antibiotic-Resistant Mycobacterium tuberculosis (TB)
- Methicillin-Resistant Staphylococcus aureus (MRSA)
- Vancomycin-Resistant Enterococci (VRE)
- Multidrug-Resistant Neisseria gonorrhoeae (Gonorrhea)

Ok, let’s go look at the history of life!
- Describe the work of Charles Darwin in the Galapagos Islands, especially his discovery of natural selection in finch populations.
- Describe how the theory of evolution by natural selection is supported by evidence.
- Recognize that mutations are the basis of microevolution; and that adaptations enhance the survival and reproduction of individuals in a population.
- Read and analyze a phylogenetic tree that documents evolutionary relationships.
