Unlike other mechanical devices, the clock did not evolve from the simple to the complex. ███ ████████ ██████ ████ ████ ███ ████ ████████████ ████ ██ ███████ █████ ██████ ████ ████ █████████ ██ ███████ ████████████ ██████████ ██████ ███ ██████████ ████ ████ ███ ████ ███████ ████████████ ███████ ███ ██ ████ █████ ██ █████ █████████ ███ ███████████ █████████ ██████ ████ █████████ ███ ███ ████████████ ████ ███████████
Summary
The clock evolved from more complex to more simple. The earliest clocks were the most complicated, because they were used mainly for predicting astronomical phenomena. As timekeeping functions became more important, and astronomical functions less important, clocks became more simple.
Strongly Supported Conclusions
The level of clock complexity required for astronomical predictions is higher than that required for keeping time.
