NS1300 – Emergence of Modern Science Evolution
2
What did Theodore Dobzhansky mean when he said, “Nothing in biology makes sense without evolution”? What are the facts? Where is the evidence? Okay, so what’s the big deal?

Voyage of the Beagle Origin of Species Wallace Natural Selection Mendel
6
Species Fecundity Stable Populations Environmental Resources are Limited Struggle for Survival Variation within Populations Differential Survivability Successful Traits Accumulate

14
Evolution is limited by history Adaptations is limited by survivability There are no future causes Chance happens Not all change is good

1. T or F, acquired characteristics can be passed on to offspring. 2. T or F, natural selection is one mechanism for evolution. 3. T or F, evolution is random. 4. T or F., the discovery of DNA structure helped bring about a “modern synthesis” in evolution theory. 5. T or F, humans and apes share a common ancestor.
