Bird Beaks Lab Report

In Biology class we conducted a lab called “Bird Beaks”, in the lab we were separated into four groups of different bird beaks. Our goal was to see which type of beak was more successful, and if evolution occurred. I claim that Evolution did occur in the bird beak lab because spoons were able to survive and grow throughout everything that occurred and tweezys were able to grow and thrive after migration and everything that followed. 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. After the migration the spoons continued to thrive ending with eight spoons even though there was another type of bird eating the food. Then after the natural disaster hit a section of the land, spoons still had five left and reproducing. After another natural selection and one mutation spoons ended with thirteen.…show more content…
At the beginning of the experiment they weren’t there yet. When they did migrate in, seven came along and began to eat the food around them. The next round after that everyone including the tweezys in a certain section were hit by a disaster. Afterwards, they once again grew in population ending that round with four tweezys which was significantly better than the spatula and scupula who had one and three. Evolution was helping the tweezys out here, at any given moment evolution could have chose to kill them off and focus on a different species. Instead evolution had this bird develop a successful beak compared to other birds beaks. After the disaster the tweezys thrived then another round of natural selection and still came in seconds after the spoon mutated. Overall evolution made tweezys’ beaks different than others to see if they survived, and when they did, evolution would keep the beak type cycling around the
