In the polyp stage, cnidarians are less vulnerable to free-swimming predators; also, polyps that form large, attached colonies are not dependent on chance encounters for sexual reproduction." |

Critical and Creative Thinking, #5 |
"Cancer is more of a problem today than it was 100 years ago because of the increase in carcinogens, especially those found in cigarette smoke. Also, in the past 30 to 40 years, more people have been overexposed to the ultraviolet radiation of sunlight. Furthermore, as people live longer, their chances of developing cancer increase." |
"Cancer is generally a disease of old age. One hundred years ago, many people died of infectious disease before they grew old enough to get cancer. Today, infectious diseases are no longer a main cause of death. As a result, people are living longer and are thus more likely to get cancer." |

Background Information, Darwin and Religion |
"Despite efforts by antievolutionists to paint Darwin as an atheist, he was a very religious man. He had a degree in theology from Cambridge and even thought about spending his life as a country preacher. He remained a devout Christian all his life. He saw no conflict—and no less awe or majesty—in a God that ruled through natural laws rather than through supernatural means. George Gaylord Simpson wrote 'Scientists certainly know more about God than the theologians do, for scientists study the works of God and theologians only study what has been felt and written about God." |
"Despite efforts by antievolutionists to paint Darwin as an atheist, he consistently refused to allow his theories to be used against religion. In the conclusion of The Origin of Species he made this point explicit: 'I see no good reason why the views given in this volume should shock the religious feelings of any one...A celebrated author and divine has written to me that 'he has gradually learnt to see that is it just as noble a conception of the Diety to believe that He created a few original forms capable of self-development into other and needful forms, as to believe that He required a fresh act of creation to supply the voids by the actions of His laws.'
