Occasionally reading a book to see such an interesting story: Scientists have done an experiment, the flea on the table, a pound the table, the flea quickly jump height of 100 times its height above. Later, the scientist covered the head of the flea with a cover glass and let it jump. This time the fleas hit the glass cover, after several consecutive times, fleas changed the height of the jump to adapt to the environment. Next, scientists gradually change the height of the glass cover, fleas in the wall after the initiative to change the height of their jump. Finally, the glass cover close to the desktop, the flea has been unable to jump again. So, scientists open the glass cover, and then beat the table, the flea is still not jump, into a climb
