Document Summary
Penicillin was the first antibiotic drug based on a valuably occurring substance that kills bacteria. The surviving bacteria reproduces and the microorganisms become more common in the later generation. The evolution of antibiotic resistance in bacteria is an example of a microevolution (a heritable change in the genetics of the population. A population of organisms include all the individuals of a sigh species that live together in the same space and time. Darwin recognized the importance of heritable variation within populations he also realized that __ selection can change the pattern of rauation in a population from one generation to the next. Phenotypic variation: the ______ in appearance or function - __ are passed from generation to generation. 17. 1a evolutionary biologists describe and quantify phenotypic variation. Quantitative variation: individuals differ in small environmental ways. Qualitative variation: they exist in 2 or more discrete states intermediate forms are often absent (ex: snow gasses have either blue or white feathers. )
