Charles Darwin observed a unique beak size and shape in the finch population of each of the Galapagos Islands that he visited. Which is the most likely cause of the observed variation?

In terms of natural selection, what is the best description of an organism that is fit?
Scientific investigations often lead to the formulation of new scientific questions. Charles Darwin reviewed his observations after he returned home from his voyage studying the selective breeding of pigeons. Which question would he be prompted to ask based on his voyage?
A frog has more offspring than can survive on available resources.Of which is this an example?
A population of rabbits has individuals with fur coloring that ranges from white to brown. The population lives in a temperate deciduous forest where the summers are mild and average about 50°F. The winters are often below freezing. If warmer temperatures last longer into the fall and the average temperature in the winter is getting warmer, what do you expect to happen to the population?
