Please do not start this until we discuss it in class. Remember, you can discuss this as a group but everyone should submit their own answers.
Here are some quick vocab words that might be helpful to know:
- Fitness – an organism’s ability to survive and reproduce (more surviving offspring = fitter)
- Adaptations – traits that are favorable in a specific environment (random and formed by mutations from generation to generation)
- Natural Selection – when an organism has more offspring because of a favored genetic trait
- Evolution – a change in trait/allele frequency over time

Which birds were the most fit (likely to survive and reproduce) on Island 1 (skittles)?
Which birds were the most fit (likely to survive and reproduce) on Island 1 (skittles)?

Explain why one beak was most favored and why others were less favored on this island (don't overthink this - you're just talking about the shape of utensils and food! You can just write a sentence or two!). Use the term fit/fitness/fitter and adapt/adapted/adaptation in your answer (scroll to the top to see the definitions).

Suppose we began our competition for food with a population in which everyone had exactly the same beak. For example that on the skittles island every bird had started with a “fork” beak. Describe why natural selection might not occur on this island.
Note: The only way for a new beak to arise is if there is a random mutation that would lead to a new beak and this takes time. These mutations won't happen just because you "need" them to happen.

Suppose we began our competition for food with a population in which there was an equal number of birds with fork/knife/spoon beaks. There is also enough food for all of the birds (plenty of pretzels, skittles, and worms). Describe why natural selection might not occur on this island.
