How is the phrase "the present is the key to the past" used in creating evidence for continental drift? What will be an ideal response?
Organisms probably lived in the types of environments where they live today, so a freshwater species
would probably not be found in salt water and a seed that would now be too heavy to float in the
atmosphere would have been too heavy in the past. Glaciers probably formed in the same
environments that they do now and not in the middle of the ocean. Similar rock sequences probably
indicate that the rocks are related to each other geologically and did not randomly generate the same
sequence.
