Assignment:
Possible topics for discussion:
1. Levine had suggested a DNA structure composed of quadruplexes of the 4 nucleotides connected together (discussed in part 6). Why would this model not be able to explain the biodiversity on Earth?
2. What does it mean for a hypothesis to be falsifiable and why is it important?
3. Mutations can have a positive, negative, or neutral effect on the fitness of an organism. What do you think is the relative frequencies of these mutations? Explain your reasoning and support it with evidence and/or examples.
4. Which processes could be drivers of macroevolution?
