Introduction A key concept in evolutionary biology is that divergent selective regime will often generate and maintain some type of phenotypic diversity (Langerhans et al. 2003). This divergent selection can lead to differences in phenotypic expression either by a genetic differentiation or phenotypic plasticity (Levins‚ 1968; West-Eberhard‚ 1989: Robinson and Wilson‚ 1994; Orr and Smith‚ 1998; Schluter‚ 2000; cited in Langerhans‚ 2003). Such divergence is significant as it can influence microevolutionary

he gave me six months more.” Doctors are only given certain amount of time to save a patient’s life. Without biology and chemistry an operation cannot be performed in a doctor’s life. The most interesting subjects in my life are biology and chemistry. These depth subjects have changed my life. Biology and chemistry changed my life and how I approach the world before. Now‚ I knew how the human body works. It heals when we get paper cuts and when we have little minor accidents that we don’t even observe

Biology through the Eyes of Faith Richard T. Wright This is an awesome book. It describes the outlook of biology not only through the eyes of faith‚ but from a Christian theistic point of view. In Biology through the Eyes of Faith‚ it explains the difference between a scientist’s perception of nature oppose to a Christian’s perception. Scientists say the world evolved which conflicts with the theistic view‚ which says the world came about through the creator God. In chapter 1‚ Professor Wright speaks
