“Lactose Intolerance: The Co-Evolution of Genes & Culture” questions (complete after viewing the film linked to slide 11)
1. What profound cultural changes occurred about 10,000 years ago that had a major biological impact on our species?
2. All infant mammals can digest milk, but what happens when they stop drinking milk? The only mammal group that can tolerate milk past infancy are some humans – why do you think that is?
3. About how many adult humans worldwide can digest milk? Are they the norm, or the exception to the rule?
4. Explain how the lactase persistence mutation has come about using evidence from culture, genetics, and historical discoveries to support your explanation.
5. Being able to digest milk is considered an adaptation, or selective advantage. What might be some advantages to being able to digest milk?

Lizard Olympics
Describe how the following adaptations gave lizards an advantage in their habitat.

Shot legs
Toe pad size
The Experiment
What hypothesis were the scientists testing when populating the storm-damaged islands with lizards?
Describe the measures taken by the scientists to ensure the validity of their data.
Concluding Thoughts
What is meant by the term reproductive isolation?
Why would scientists use molecular evidence (DNA) to develop the phylogenetic tree of the lizard populations instead of comparative anatomy?
