Document Summary
Bgyb51: chapter 2 (pages 37 49 and 53 65) The first scientist to give a definition of species, john ray, states that [o]ne species never springs from the seed of another. Darwin also introduced a process to explain this pattern called natural selection. The living evidence for descent with modification comes in two forms: by monitoring natural populations, we can directly observe small scale change (i. e. microevolution) If we examine the bodies of living organisms, we can find evidence of dramatic change (i. e. macroevolution) Direct observation of change through time: read examples of the change of the soapberry bug over time on page 40. These muscles are effective for animals that are very hairy like chimpanzees. Most of us are not that hairy (except some of you hormone excessive freaks), and thus the result of these muscles contracting is goose bumps.
