<span>Stabilizing selection is at work in this case. This is the force that allows a population to gradually center on a mean value due to a presence of a non-extreme bodily trait. The more extreme examples of the trait lead to the organisms being selected out, and the trait that is the least conspicuous wins out in the long-run.</span>
<span>The most dominant chemolithotrophs in pelagic waters are ammonia-oxidizing archaea. The first step in nitrification is performed by ammonia oxidising microorganisms that convert ammonia into nitrite ions. Science has known about nitrifying bacteria for over a hundred years now thanks to the discovery of S. Winogradsky.</span>

Explanation:
Artificial human insulin is the advancement of the field of biotechnology. It is the product of recombinant DNA technology. The insulin is a hormone which is secreted by the pancreas to maintain the levels of sugar in the blood. But in some people the secretion of insulin can be found to be low or no insulin is produced at all these are affected by the condition called as diabetes. Thus artificial or synthetic insulin was invented to regulate the blood sugar levels. The artificial insulin is produced in the microbes like yeast and bacteria. The human gene encoding for the production of insulin is inserted into the microbial genome which produces the insulin in the microbial structure.
