Who originally said that change is the only constant? Roman philosopher Lucretius 2,000 years ago When was Darwins Origin of Species written? 1859 Describe Darwin's theory of natural selection. There is, he argued, tremendous variation among the members of any given species. Some of these variations are well suited to current conditions; others are not. Individuals with favorable variations are more likely to survive and reproduce, so succeeding generations are more likely to show helpful characteristics. Thus, features that contribute to survival are "selected" by the environment, a process Darwin called natural selection. Was Darwin aware of the genetic basis for evolution by natural selection? no Who was the first person to understand the role of genetics? Gregor Mendel (father of genetics) published his work in 1866. Although Darwin did not understand the genetic basis for evolution, he was aware that _____ (2 things) variation within a species was common selective breeding of farm animals with a specific variation often resulted in offspring with that characteristic. What did Dawkin's pebbly beach analogy illustrate about natural selection? pebbles arrange themselves based on the flow of water and density and size of the rocks. Intelligent direction isn't required. The environment "selects" desirable characteristics and spurns undesirable ones. What are mutations? Abrupt changes in genes. What can cause a mutation? Can be caused by exposure to radiation and certain chemicals and perhaps by viral infections. In what case will mutation be passed on to the next generation? when mutations occur in genes of reproductive cells (sperm or ova) Can mutations occur in any cell of the body? yes Will offspring with mutated genes necessarily display the mutation? no Are mutations always detrimental to survival? Many of these changes are simply of no consequence, one way or the other Occasionally can be useful to survival. (new horn mutation useful for defense) What is a reflex? A reflex is a relationship between a specific event and a simple response to that event. A
