In a peptide bond formation between two amino acids, a water molecule (A) is liberated. This reaction is called condensation. The water molecule is formed by a single hydroxide ion being removed from one amino acid, and a single hydrogen ion from the second amino acid, which combine to form a water molecule.
He inferred that similar changes had happened in the past. Uniformitarianism combines the idea of gradual change over time with Lyell's observations that such changes have occurred at a constant rate and are ongoing.
<span>Natural selection is likely when there are stronger selection pressures. For example, a perpetual selection pressure is the fact that organisms have to compete for food and resources, meaning the best adapted ones survive. However, a stronger selection pressure may cause natural selection to occur more obviously. An example of this is when the number of white peppered moths decreased during industrialization in England due to the soot collecting on the trees. The change in population was very fast and obvious.</span>
