Lab: Natural Selection-Standard Bio 4.2 Answers

Did you record all data throughout the virtual lab experiment?

Look at your data. With three foods, Flock was the most successful over three generations.

With two foods (no fruit), Flock was the most successful.

The flocks all started with 10 birds. Flock was the most successful at feeding, so it will have the greatest number in the second generation. Flock was the least successful at feeding and has shrunk the most.

* Divide each flock's total pieces of food by 300, the total number of pieces of food eaten. ** Multiply the food percentage for each flock by the total number of birds (30).

* Divide each flock's total pieces of food by 300, the total number of pieces of food eaten. ** Multiply the food percentage for each flock by the total number of birds (30).
