The theory of punctuated equilibrium is a theory of evolutionary biology that aims to explain the pattern of speciation, which is observed in the fossil records. It states that the organism is in the stasis, until a major changes cause evolutionary pressure, which leads to a rapid speciation until stability is again reached between the organism.
Example: A species of sea animals live, breed and dies from thousands of years, suddenly the sea level changes and animals adapt to that situation.
The theory of punctuated equilibrium states that is a species appear in a fossil record, they will become stable over time and can show little changes in evolution as time goes by. An example would be the feline creatures. Although cats and tigers have a different structure in their body, the facial structure and the way they hunt are similar.
