Darwin had initially expected the living plants of temperate South America to resemble those of temperate Europe, but he was surprised to find that they more closely resembled the plants of tropical South America. The biological explanation for this observation is most properly associated with the field of → c. more recently they shared a common ancestor.

In the mid-1900s, the Soviet geneticist Lysenko exposed winter wheat plants to ever-colder temperatures, collected their seeds, and then exposed the seedlings to ever-colder temperatures. He repeated his attempts over the course of decades in an attempt to evolve cold-tolerant winter wheat. Lysenko's attempts in this regard were most in agreement with the ideas of → c. more recently they shared a common ancestor.
