Theory of punctuated equilibrium may also know as punctuated equilibria, it was first presented in 1972 by Niles Eldredge and Stephen Jay Gould, the pattern describe is by the long duration of stability after the rupture patterns of evolutionary change.
I go with Ice Core examples since early sociteties probably didn't have Written Records or maps, and tree rings would only tell if they were fossilized. I hope this helped :)
To divide reproductive cells
1 Glycolysis:Glucose means “glucose splitting,” which is exactly what happens in this stage.
2 Anaerobic and Aerobic Respiration: Cellular respiration that proceeds without oxygen Structure of the Mitochondrion: Key to Aerobic Respiration
The Krebs Cycle:These molecules enter the matrix of a mitochondrion, where they start the Krebs cycle
3 Electron Transport: This is the result of the Krebs cycle, and is now transferred to ATP.
