In the rock layers below the Antarctic, a region currently covered in ice, scientists have discovered the remains of plants that usually live only in very warm climates. What is the most reasonable conclusion for scientists to draw from this evidence?

• The antarctic will be covered in ice for millions of years.

• The climate in the antarctic was very different in the past.

• These plants have adapted to live in the antarctic.

• The antarctic has daylight for only six months of the year.
