Bean+Passes+Graph

media type="custom" key="7250535"

A: When we tried passing with our UR-1 (thumb) and UR-2 (point finger) and with UR-1 and UR-3 (middle finger) we had the the most number of passings because we are mostly used to use those fingers and we are mostly adapted to those fingers to pick little things up.

Q: What are some conclusions you can develop from looking at this data?

A: One conclusion i can make is that the more farther you go away from the thumb or not use your thumb the number of passings are lower, because it is more harder to pass with you other fingers beside your thumb. Also the fingers that are most separated besides not including the thumb. For example your second and fifth finger are the farthest apart when not including the thumb. We also had the least number of passes when we were using those fingers.

Q: What might 2 or 3 sources of error that occurred during this experiment?

A: One source of error is that we would keep dropping the bean and then would have to start counting fromt he start again when the clock is still ticking. Also sometimes for some people when they bring down a finger another finger might come down with it, and accidentally while doing the passing process they change fingers, which would would make us have to start over again.

Q: HOW DOES THIS LAB DEMONSTRATE “ADAPTATIONS”?

A: This lab demonstrates adaptation because adaptation is the evolutionary process whereby a population becomes better suited to its habitat. This process takes place over many generations, and is one of the basic phenomena of biology. The people with thumbs get used to it and keep using it. they soon get adapted to it. People also soon realize that they need the thumb for almost everything and mostly need it for picking things up. overall things are much better to pick up and grab and many more with the help of your thumb. Y=] Also because its a specifiic feauture that you use in everyday life in order to survive!
