Darwin studied actual birds on the Galapagos Islands instead of using a simulation, as you did in this lab. Studying natural selection in the field can be challenging. List at least three possible challenges Darwin might have faced.

Answer:

Darwin faced several challenges while studying finches in the Galapagos. First, adaptation through natural selection often takes many generations to observe, which can span decades. Second, the natural environment is incredibly complex compared to a simulation, making it difficult to control for variables like weather or food scarcity. Third, traits other than beak type, such as a bird's size or behavior, might also influence survival, making it harder to determine which specific trait is being selected for. Finally, birds have interdependent relationships with other organisms in their ecosystem that may also be changing.
