In biological sciences, morphology is the branch that studies the form, external structure, and macroscopic organization of organisms and their parts, independent of function. It encompasses comparative morphology, which analyzes homologous structures across taxa; functional morphology, which relates structural features to mechanical or biomechanical constraints; and developmental morphology, which examines changes in form during ontogeny. Morphological data, including body plans, organ systems, and patterning of tissues, are central to systematics, phylogenetic inference, and taxonomy, and are integrated with molecular and genetic information to elucidate evolutionary relationships, phenotypic variation, and constraints on organismal design.
A paper published in Science describes the discovery of Spinosaurus mirabilis, a new spinosaurid species found in Niger. A 20-person team led by Paul Sereno, Ph.D., Professor of Organismal Biology and Anatomy at the University ...

There may be twice as many vertebrates on the planet as previous estimates claimed, according to a new study published in the journal Proceedings of the Royal Society B: Biological Sciences. That's not because of any errors ...
Have you ever seen a hibiscus flower? Although its petals have a range of colors, what makes the trumpet-shaped flower more beautiful is the central stalk, which houses the anthers that produce pollen grains. Powdery in structure, ...
