The document discusses three triads that describe evolution: biological evolution has functional, historical, and structural aspects; technological evolution also has three aspects - the semiconductor industry arose contingently but led to Silicon Valley, the ARPAnet network was structurally inevitable and became the internet, and Apple computers were intentionally created to have a graphical user interface.

1. Triad of Evolution Variations of the Technium

2. Triad of Biological Evolution Functional/Adaptive External Variations Physical/Chemical Constraints Internal Variations Self-Organizing

3. Triad of Biological Evolution Historical/Contingent Random Acts of Chance No Pattern/Direction

4. Triad of Biological Evolution Structural/Inevitable Independent of History Predictable

5. Triad of Technological Evolution
