Bird Beaks Lab Report
578 Words | 3 PagesIn Biology class we conducted a lab called “Bird Beaks”, in the lab we were separated into four groups of different bird beaks.

My first piece of evidence and reasoning, is that spoons survived throughout the whole experiment after two natural selections, a migration of tweezys, a natural disaster, and a mutation. We started with seven spoons and ended with thirteen spoons.

What Are The Arguments Against Darwin's Theory Of Evolution

The larger beaked birds fed off of hard shelled nuts, while the smaller beaked birds fed off of smaller seeds and nectar from plants.
