The Pancreatic Emergence
The evolution of the pancreas marked a significant shift. Specialized cells, harboring increasingly refined proteolytic machinery, began to coalesce. Elastase, initially a minor component, gained prominence due to its efficacy in cleaving elastin – a crucial protein in connective tissue. This adaptation allowed for more efficient nutrient absorption, particularly in organisms with complex digestive tracts. The temporal pressure of this evolutionary stage resulted in a substantial amplification of elastase’s catalytic potential, driving a feedback loop of increased breakdown rates.
