Based on (MS-LS4-4) standard(grade8) - Mathematical Representations of Natural Selection: Based on the 'Galapagos Islands Finch - 25 cm Average Rainfall' dataset ( picture attached)This data set shows data from a population of finches for a period of five years when there was always an average rainfall of 25 cm per year.    1.    What changes are observed in the beak depths of the population over the period of five years?    2.    What is the average change in beak depth over the five-year period? Based on the data provided, does this change seem significant?  Explain it.

Question

Based on (MS-LS4-4) standard(grade8) - Mathematical Representations of Natural Selection:
Based on the 'Galapagos Islands Finch - 25 cm Average Rainfall' dataset ( picture attached)This data set shows data from a population of finches for a period of five years when there was always an average rainfall of 25 cm per year.   

1.    What changes are observed in the beak depths of the population over the period of five years?   

2.    What is the average change in beak depth over the five-year period? Based on the data provided, does this change seem significant?  Explain it. 

 

Geospiza magnirostris Geospiza fortis The Galápagos Islands are very dry, with an average rainfall on some islands of only 12 centimeters per year. The amount of rainfall has a large impact on the abundance and types of seeds that are available to be eaten by finches. In the process of natural selection, only the finches that are best adapted to the available seed types survive and have offspring. In years of extreme drought, Galápagos plants don't produce new seeds. The small, delicate seeds get eaten up quickly, leaving behind only the largest, toughest seeds. In years of excess rainfall, plants on Galápagos islands produce seeds in abundance. Current average depth 9.87 mm The 'Depth' of a beak is measured brom the lowest point to the highest point of the beak.
