分子生物学 (molecular biology) focuses on the molecular basis of biological activity, while 分子進化学 specifically studies evolutionary change at the molecular level.
進化学 (evolutionary biology) is a broader field covering all aspects of evolution, whereas 分子進化学 is a subfield concentrating on molecular data.
Compound of 分子 (ぶんし, 'molecule'), 進化 (しんか, 'evolution'), and 学 (がく, 'study'). The term is a direct calque from English 'molecular evolution'.
