The document discusses key concepts in natural selection such as variation being caused by changes in the environment, well adapted individuals having the best chance of reproducing, and mutation being a source of variation for natural selection. It also notes that natural selection is not a random process and acts in a non-random way on genetic variation in a population by favoring variants that aid survival and reproduction.

8. Which is the final event that occurred during
the process of resistance to antibiotics?

9. • it is a misconception to view natural selection as a process that perfects
organisms.
• At the opposite extreme, natural selection is sometimes interpreted as
a random process. This is also a misconception.
• The genetic variation that occurs in a population because of mutation is
random — but selection acts on that variation in a very non-random way:
genetic variants that aid survival and reproduction are much more likely
to become common than variants that don't.
• Natural selection is not random!

10. An adaptation is a feature produced by natural
selection for its current function.
Is it heritable?
Is it functional?
Does it increase fitness?
