Adaptation by natural selection over several generations is one important process by which species change over time in response to changes in environmental conditions. Traits that support successful survival and reproduction in the new environment become more common. Those that do not become less common. Thus the distribution of traits in a population changes. Take a look at the table below. The left column lists examples of environmental changes. For each example, describe an adaptation that would help a plant or animal survive. Be creative but accurate; there are many possible answers
