Seeing structure, losing sight: The case for morphological thinking in the age of integration

In the age of genomics, artificial intelligence (AI), and systems biology, morphology risks becoming an invisible discipline, present in the background, but often unacknowledged in its interpretative power. Biology, however, remains spatial, structured, and shaped. From subcellular compartments to complex organ systems, form continues to inform function. The ability to recognize, describe, and interpret structures across biological scales is a foundational scientific competence. Morphology is not merely descriptive; it is integrative. Morphological sciences bridge developmental, cellular, and evolutionary biology, revealing how gene activity, signaling dynamics, and mechanical forces influence biological architecture. Morphological thinking enables scientists to contextualize molecular processes within the spatial complexity of cells, tissues, and organs. Paradoxically, while technological tools for visualizing structures are expanding rapidly, the number of scientists trained in morphological reasoning is shrinking. If left unaddressed, this erosion threatens to undermine both the scientific depth and translational relevance of biological research. This commentary argues that rediscovering morphology is not a nostalgic act, but a necessary one. We must affirm morphological thinking as a core scientific competence, reframe educational practices to sustain spatial reasoning, and integrate morphology into the evolving world of AI-driven imaging and systems biology.
