Neutral mutations do not affect the organism's chances of survival in its natural environment and can accumulate over time, which might result in what is known as punctuated equilibrium, the modern interpretation of classic evolutionary theory. Most biologists believe that adaptation occurs through the accumulation of many mutations of small effect. However, macromutation is an alternative process for adaption which involves a single, very large scale mutation. The change brought about by a mutation is either beneficial, harmful or neutral. If the change is harmful, then it is unlikely that the offspring will survive to reproduce, so the mutation dies out and goes nowhere. If the change is beneficial, then it is likely that the offspring will do better than other offspring and so will reproduce more. Through reproduction, the beneficial mutation spreads. The process of culling bad mutations and spreading good mutations is called natural selection.# As mutations occur and spread over long periods of time, they cause new species to form. Over the course of many millions of years, the processes of mutation and natural selection have created every species of life that we see in the world today, from the simplest bacteria to humans and everything in between. Scientists have shown that beneficial mutations do occur to produce brand new alleles (variants of genes) that improve an organism's chances of survival in a particular environment. Natural selection has been demonstrated to increase the frequency of these alleles in a population. The easiest way to demonstrate this is from experiments based upon lines of organisms developed from clones (genetically identical by definition) of a single individual. The following examples are from pages 1. I list the original references for some of these so that anyone who wants more details will know where to look. The title of the section from which these examples come is .

A single clone was then extracted from this population and divided into replicates that were then cultured at either 3. C , 3. 7 C, or 4. C for a total of another 2. By the end of the experiment, the lines cultured at 3. C were shown to be 1. C), and the line cultured at 4. C was shown to be 2. The replicate line that was cultured at 3. C showed little improvement over the ancestral line. Bennett, A. F., Lenski, R. E., & Mittler, J. E. Evolutionary adaptation to temperature I. Fitness responses of Escherichia coli to changes in its thermal environment. Evolution, 4. 6: 1. Adaptation to Growth in the Dark by Chlamydomonas. Chlamydomonas is a unicellular green algae capable of photosynthesis in light, but also somewhat capable of growth in the dark by using acetate as a carbon source. Graham Bell cultured several clonal lines of Chlamydomonas in the dark for several hundred generations. Some of the lines grew well in the dark, but other lines were almost unable to grow at all. The poor growth lines improved throughout the course of the experiment until by 6. This experiment showed that new, beneficial mutations are capable of quickly (in hundreds of generations) adapting an organism that almost required light for survival to growth in the complete absence of light. Selection for Large Size in Chlamydomomas. Bell also selected clonal lines of Chlamydomonas for size by passing cultures through a fine filter and discarding the cells that were not retained on the filter. He reports that although this method was not very effective at retaining the largest cells (due to inconsistencies in the filter pore size), after forty generations of this selection technique, the cell diameter had increased by an average of about 1 phenotypic standard deviation.
