<span>Peter Raymond Grant, FRS, FRSC, and Barbara Rosemary Grant, FRS, FRSC, are a British couple who are evolutionary biologists at Princeton University. Each currently holds the position of emeritus professor. They are known for their work with Darwin's finches on Daphne Major, one of the Galápagos Islands. Since 1973, the Grants have spent six months of every year capturing, tagging, and taking blood samples from finches on the island. They have worked to show that natural selection can be seen within a single lifetime, or even within a couple of years. Charles Darwin originally thought that natural selection was a long, drawn out process. The Grants have shown that these changes in populations can happen very quickly.</span>

Explanation:
<span>1. What is an endotherm?
Endotherm is an animal that keeps their temperature constant in a certain range. Keeping temperature is important because most enzyme has an optimal working range. By keeping the temperature at optimal range for the enzyme, the organism can do metabolism more efficient.
2. how do sweating, fur, and feathers affect the body temperatures of endotherms?
The environments temperature should influence the temperature of an organism that lives within it. </span>Endotherms need to control their temperature, so they have some mechanism to increase/decrease the body temperature. or to insulate themselves from the environment.
Sweating help decreasing temperature makes the organism can withstand hot environment. Fur and feather will insulate the body, makes the organism more resistant to cold.<span>
