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?
Do living things change over time, and if so, how?
Are the Galapagos finches and those on the mainland the same species?
Are pigeons related to the Galapagos finches?
Can selection in nature also lead to a new species over time?
