Textbook Question
Chapter 20, Problem 12P
Biologists have proposed that the use of antibiotics to treat human infectious disease has played a role in the evolution of widespread antibiotic resistance in several bacterial species, including Staphylococcus aureus and the bacteria causing gonorrhea, tuberculosis, and other infectious diseases. Explain how the evolutionary mechanisms mutation and natural selection may have contributed to the development of antibiotic resistance.

How does the increasing frequency of anabiotic resistant strains of bacteria represent an example of the occurrence of evolution? Include the three criteria for natural selection in your explanation. 
Humans in the 21st century use their thumbs extensively to operate touchscreens on cellphones. Imagine a scenario, where the human population evolves to have more dexterous thumbs over the next 300 years. Which of the following is a Lamarckian explanation for this evolutionary change (and, therefore, would an incorrect evolutionary mechanism?)
humans that develop more dexterity in their thumb over their lifetime due to frequent use of cellphones pass that ability to their children
humans that were born with a mutation for more dexterous thumbs have more children
thumb dexterity is a dominant trait
Considering the evolution of species, could a gene that is conserved from yeast to humans have evolved to confer some of the complex traits that we observe in modern animals, like multicellularity? Briefly explain.
