Document Summary
Biob51fall2011 chapter 2: the pattern of evolution - lecture 3 and 4 and 5. The theory of special creation has 2 components. The first component is a set of assertions: species do not change through time, they were created independently of one another, and they were created recently. The second component identifies the process that is responsible for producing the pattern: separate and independent acts of creation by a designer. Darwin came up with the theory of descent with modification. Claimed that: specie are not immutable, but change through time, species are derived not independently but from common ancestor, the earth and life are considerably old. By monitoring natural populations we can directly observe small scale change or microevolution. If we examine the bodies of living organisms, we can find evidence of dramatic change or macroevolution. Soapberry bugs feed by using their long beaks to attack the inflated, balloon like fruit capsules of their host plants.
