In the "Darwin and the Racing Asparagus" audio essay linked to the Topic 2 (What Is Evolution?) webnotes (just above the  Key Concepts), why was Darwin experimenting with floating vegetables and seeds? He wanted to find a mechanism that could explain the distribution of life forms, like plants, that cannot fly or swim to new,  distant locations. He was basically just a wacko who abused his butler by making him do weird things. He wanted to see how long they would stay alive/viable while floating on the open sea. He wanted to test the nutritional value of vegetables soaked in sea water. Question 2    1 / 1 point According to the audio essay on Darwin, can clams "fly" (and who cares)? Yes, in the sense that they can be transported from pond to pond by hitching a ride on flying insects, such as beetles. Yes; this is important because it demonstrates that organisms that seem to have limited ways of moving around, can  disperse over long distances. Of course not! They can swim, but they cannot move through the air by any means. No. And no one cares. Question 3    1 / 1 point Which of the following statements about the status of the theory of evolution by natural selection is/are correct? Evolutionary theory is controversial in the scientific community; it is a theory in crisis. Evolutionary theory is one of the foundations of modern biology; it is accepted by the vast majority of scientists.
