evolution
🧬 进化 = 进 (advance) + 化 (change) → evolution
进 means advance/enter; 化 means change/transform. Together, advancing change = evolution. Same 化 appears in 文化 (culture = literary transformation) and 变化 (change).
进 — walk radical 辶 + well 井
Originally a semantic-phonetic compound: the walking radical 辶 gives the meaning of movement, while 井 (jǐng, 'well') supplied the sound. The traditional form 進 used 隹 (short-tailed bird) suggesting forward flight; the simplified 进 swapped 隹 for the simpler phonetic 井. The core meaning 'to advance, enter' has stayed stable.
化 — person 亻 + spoon/upside-down person 匕
化 is an associative compound showing a standing person 亻 next to 匕, originally a depiction of a person turned upside-down. Together they suggest a figure transforming from one state to another, giving the core meaning 'change' or 'transform'. The character later extended to senses like 'convert', 'influence', and the noun suffix '-ization'.
