Bird Beak Conclusion

     In this lab we asked the question, if natural selection occurs in a population, how do changes in selective pressures affect the evaluation of that species? We found that the beak with the most versatility and convenience for the current situation will survive the longest. In our case it was the "tweezers beak" that survived the longest. Please refer to the part one graph.

The  "tweezers beak" is the second from the right

    In this part of the lab we experimented with different environmental situations that affected the survivability of our bird beak. Our environmental factor was that our ecosystem had a famine and instead of requiring 5 grains of food we needed 10 pieces of food to produce an offspring. Please refer to the graph. 

     Some possible errors would be that the food was not distributed evenly among us so other people had an unfair advantage over the other.  To fix this problem we could maybe count the amount of food in a specific area to evenly distribute it. We did this lab to demonstrate the process of natural selection and evaluation. Based on my experience from this lab I am able clearly understand evaluation.
