Charles Darwin 1880 By: Elliot & Fry |
Charles Darwin is a scientist that lived in the 19th century and made major break troughs when is came to evolution. Charles Darwin was studying Finches on the Galápagos islands, when one day he noticed that on each different islands, the finches had different characteristics. He also noticed that each type of finch was better suited for its environment, than the other types of finches. He then made the hypothesis that that animals with more survivable traits would reproduce, while animals that don't have those traits would die without reproducing. This process would later be known as natural selection.
SP4: Analyzing and interpreting data
While we were studying the effect of the amount of rainfall that occurred each year would cause to the deepness of a finches beak, we had studied graphs, and determined how the beaks of the finches changed, if it was significant or not, and what the cause was. We then used that data to make predictions on how different amounts of rainfall would affect the finch population.
XCC: Cause and effect
When the amount of rainfall changes, the size of finches beaks also change. When we look at the relationship between the amount of rain, and the size of finches beaks, we can learn how the finches will be effected due to major changes in the climate. We can also observe the mean average deviation for the rainfall before it starts effecting the finches. We can use this information to study not only finches, but various other organisms in a lab environment.
