- So Different | Umbo

: A paper in Scientific Reports compares the nervous systems of bivalve larvae, where the placement and development of the umbo (the highest part of each shell valve) are critical to identifying "so different" evolutionary paths between species.

: The umbo is the most depressed part of the tympanic membrane (eardrum). Research such as the Finite-Element Modelling of the Gerbil Middle Ear explores how the umbo's response to sound frequencies is "so different" when comparing experimental data to computer models. Umbo - So Different

: In botany, the umbo is a protuberance on the scales of conifer cones. Observations shared by Redwood National Park highlight how these features appear "so different" between male and female cones on the same tree. Literature: Beatrice Umbo : A paper in Scientific Reports compares the
