8. Assume that the most successful bird in the F, generation is the sole parent of the next (F2) generation. Continue to breed, test, and record data for 8 more generations.
9. Clean up your materials before leaving the lab.
Analysis and Conclusions
1. Did your selection process result in birds that fly better?
2. Describe two aspects of this investigation that model evolution of biological organisms.
3. Your most successful bird may have a different lineage from the most successful bird of your neighboring groups. Compare your winning bird with those of your neighbors. How does it differ?
4. What might happen to your last bird if the environmental conditions change?
5. How might this lab help explain the observations Darwin made about finches on the Galápagos Islands?
A flock of origami birds is blown off the mainland and onto a very small island. These birds face little danger on the ground, but they experience significant risk when flying because they can be blown off the island. Birds that cannot fly at all are most likely to survive and reproduce. Continue the experiment for several generations, selecting birds that can't fly.
