developmental biology
The scientific study of how organisms grow and develop from fertilization to maturity.
In the developmental biology lecture, we learned about the embryonic development process.
発生学 (embryology) is a narrower field focused on embryonic development, while 発生生物学 encompasses broader developmental processes including genetics and molecular mechanisms.
分子生物学 (molecular biology) studies biological processes at the molecular level, often overlapping with developmental biology in areas like gene expression during development.
Compound of 発生 (development, occurrence) + 生物学 (biology). The term is a direct calque of English 'developmental biology'.
