In recent years "SuperBugs" (bacteria that aren't effected by antibiotics) are becoming more and more common. How could natural selection explain this?

• Superbugs survive antibiotics and reproduce
• Antibiotics cause bacteria to become superbugs
• We have always had the same amount of superbugs; modern media just discusses them more.
• There is no reliable data on the origin of super bugs.

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.
