EVOLUTION/LECTURE1 file:///E|/CH2-EVIDENCE-SPRING-2008/CHAPTER2_SPR_2008.HTML[12/8/2011 11:22:00 AM] Evolution ( PCB 4674 ). Chapter 2. The evidence for evolution Main topics of lecture: I: The three main statements of the Theory of Special Creation 1.- Introduction 2.- Relatedness of life forms 3.- Change through time 4.- The age of the Earth II: Correspondence among data sets and Theory of Evolution I: General background: 1.- Introduction 1.1.- Before the establishment of the Theory of Evolution by Charles Darwin the leading explanation in Europe for the origin of species was the Theory of Special Creation . This theory held that all organisms were created by God during the six days of creation as described in the Bible's book of Genesis. The theory stated that species are unchanged since their creation, or immutable, and that variation within each species is strictly limited. 1.2.- The Theory of Special Creation also stated that creation of all the organisms was recent (approx. 6,000 years ago). 1.3.- By the time that Darwin began working with his theory dissatisfaction with the Theory of Special Creation had begun to grow. Research in the biological and geological sciences was advancing rapidly, and the data clashed with creationism's central tenets and predictions. 1.4.- Scientific theories frequently have two components: (i) A statement of a fact: A claim about a pattern that exists in the natural world (ii) Which process is responsible for this patter 1.5.- The three main statements of facts made by the Theory of Special Creation are: (i) Species were created independently of one another (ii) Species do not change through time (iii) Species were created recently 1.6.- According to the Theory of Special Creation the process responsible for this pattern was the creation by God 1.7.- In this chapter we will review evidence that supports an alternative statement:

EVOLUTION/LECTURE1 file:///E|/CH2-EVIDENCE-SPRING-2008/CHAPTER2_SPR_2008.HTML[12/8/2011 11:22:00 AM] " Species have changed through time and are related by descent from a common ancestor " This statement is the backbone of the theory of evolution as exposed by Charles Darwin. 1.8. In this chapter we will explore first data that challenges the three main statements of the Theory of Special Creation indicated in 1.5 (i.e. species are independent, immutable and recent). In the second half of the chapter we will introduce several data drawn from different fields of scientific inquiry that supports predictions of the Theory of Evolution 2.- Relatedness of life forms and homology 2.1.- The Theory of Special Creation contends that each species was created independently. In contrast the Theory of Evolution contends that organisms are related by common ancestry. 2.2.- Results from the fields of comparative anatomy and embryology demonstrate that
