Group Work -- Geologic Time
● Learning objectives
○ Generate and test a historical science hypothesis of biological process
○ Explain the sequence of earth history events
○ Explain organismal evolution by natural selection and provide
supporting examples
● What surprised you the most about the evolution of multicellular life? Why?
○ Was it a pattern or a process?
● Explain how the advent of sexual reproduction affected the evolution of early
animals?
○ Why out of sexual reproduction would variation choose to go back to
asexual reproduction?
○ Why would you evolve to be asexual from a sexual reproduction
species?
■ Extinction of a sex, more efficient, less change, possible?, more
adaptable offspring, helpful to a species which has trouble
finding a mate, more fit if every individual of the species can
contribute

Document Summary
Generate and test a historical science hypothesis of biological process. Explain the sequence of earth history events. Explain organismal evolution by natural selection and provide supporting examples. Extinction of a sex, more efficient, less change, possible?, more adaptable offspring, helpful to a species which has trouble finding a mate, more fit if every individual of the species can contribute. Sexual reproduction can spread novelty quickly over just a few generations. Cellular respiration more energy produced (than photosynthesis) grow bigger, live easier, sexual reproduction means they can have variation. Oxygen into the atmosphere larger animals. Animals that were larger (b/c of oxygen) they could move faster and/or be larger predators would more to top of food chain. Natural selection response to predators and omnivores. Hypotheses: because animals can move now, they can cover more area, food source was diversified, More fossils would be dispersed after they moved.
