Final answer:
Thales, an ancient philosopher, exemplified early scientific investigation by predicting natural events like solar eclipses and seeking logical, natural explanations for phenomena, highlighting the transition to natural philosophy.
Step-by-step explanation:
The ancient philosopher Thales is an exemplary figure who engaged in activities resembling natural science through his explanation of natural phenomena by natural causes. One of his scientific contributions includes predicting a solar eclipse in 585 BCE, possibly using Babylonian astronomical records, showcasing his understanding of natural events and their explanations. Thales is known for being among the first to move away from supernatural explanations, instead suggesting that natural occurrences had underlying, discoverable reasons.
This step towards seeking logical explanations and employing observation can be seen as a foundational element of what we now consider scientific inquiry. The belief that material elements could change and possess their own source of motion, leads us to consider Thales' attempts to understand the world as part of the beginnings of natural philosophy, the precursor to modern science.
