What environmental variable caused the beaks in Galapagos finches to evolve?
Changes in the weather led to changes in the food supply available. Sometimes there would be hard nuts, and the finches with tough beaks would survive. However, if, on that same island, the weather changed and longer beaks would be advantageous, the tough-beaked finches would die out and slender beaks would dominate. This is proven by the extensive research carried out by Peter and Rosemary Grant from 1973 to the present.

What evidence did the work of Rosemary and Peter Grant provide that strengthened Darwin's hypothesis about the finches of the Galapagos islands?
The couple spent years observing and documenting environmental conditions of Galapagos finches and how it related to beak structure. They discovered that environmental changes favored certain individuals who in turn, passed those favored traits on to their offspring. This occured more rapidly than previously supposed.
In Rosemary and Peter Grant's study of the Galapsgos finches what process was encouraged by ecological competition during the dry season?
The process encouraged by ecological competition during the dry season in the Galapagos finches study was natural selection. Drought conditions led to limited food resources, resulting in increased competition among finches for survival. Those with traits better suited for obtaining food were more likely to survive and reproduce, passing on their advantageous traits to the next generation.
