Below are two common misconceptions about evolution by natural selection. Choose one of these two misconception and (1) explain why it is incorrect and (2) explain the correct evolutionary concept. Two common misconceptions (incorrect views) about evolution by natural selection: Individuals evolve Evolution leads to more complex organisms that are the best; humans, by this measure, are the most successful evolutionarily Please explain in a paragraph, a minimum of 4-5 sentences.

Mad cow disease results from a proteinaceous infectious particle, or a misfolded prion protein. The infectious prion catalyzes the misfolding of normal prions of our central nervous system into infectious forms, which then catalyze the misfolding of yet more normal prions. In this manner, prions spread in the brain until host death. Considering a classic definition of life (e.g., as provided by our textbook), are prions alive?

A patient with tuberculosis (causative agent: Mycobacterium tuberculosis) is treated with antibiotics. Feeling better, the patient doesn’t finish the course of antibiotics, and the infection worsens. This time, the infection is not controlled by the same antibiotic, and M. tuberculosis are found to be resistant to that antibiotic. Why is this?
