Smaller teeth and jaws are due to genetic variation, which occurred by mutations (errors in DNA replication) and were selected to fill a suitable niche.
<h3>What is evolution?</h3>
Evolution is the mechanism of change of one species to adapt given environment, whereas mutations are the raw material for evolution.
In this regard, scientific evidence supports the fact that jaws evolved to become shorter in humans and thus adapt to a pastoral lifestyle.
In conclusion, smaller teeth and jaws emerged by mutations and were selected to fill a suitable niche.

The reaction being described is; CO2 + H2O = H2CO3 This reaction will be affected if carbonic anhydrase acts as a catalyst will be; that H2CO3 (carbonic acid) will be produced faster. Carbonic anhydrase enzyme balances the pH of the blood and also enables the breathing out of carbon dioxide. The reaction above catalyzed by the enzyme takes place in the red blood cells where carbon dioxide is converted into carbonic acid, which further breaks down into bicarbonate ions and protons.
The cell cycle can be separated into two major phases that alternate with each other: interphase, during which the cell grows, prepares for mitosis and duplicates its DNA, and the mitotic (M) phase, in which the cell divides into two genetically identical daughter cells.
