refers to the differences in physical form and structure—such as size, shape, color, and internal anatomy—observed among individuals of the same species or between different species. It is a fundamental concept in biology that helps scientists understand how organisms adapt to their environments and how new species evolve over time. Types of Morphological Variation
(liverwort) exhibit "cryptic" morphological variability that is difficult to quantify manually. Modern researchers use deep learning image classifiers ---- Morphological Variability
