Furca, a prehistoric arthropod; Furca (springtail), an anatomical structure in springtail entognaths. Caudal furca ("tail fork"), part of the telson of some crustaceans; Furcula, the wishbone of birds and some dinosaurs; Furcula a genus of Noctuid moths; Any small forked structure of animal anatomy
Furca fossils have been found in sediments indicative of shallow marine habitats. Since appendages and other body parts are unknown, no firm conclusions can be made of the biology of Furca. However, comparisons to other marrellomorphs and living arthropods such as horseshoe crabs suggest a benthic marine lifestyle: dwelling on the sea floor. [2]
The furca allows for distant jumps relative to the body length. Entomobrya dorsalis which has a length of less than 2 mm long, uses their furca to jump up to 16 cm. Sminthurus viridis has a jump where the acceleration peaks were measured at 970 m / s², which corresponds to an acceleration of phenomenal 98.9 g (compared to 3.0 g for an ...
Scolecofurca is a genus of stem-group priapulid worm [2] dating from the Middle Cambrian period approximately 505 million years ago.. It is known from a single fossil specimen from the Raymond Quarry in the Burgess Shale in the Canadian Rockies.
Forked cross Forked cross in St. Mary's in the Capitol, Cologne. A forked cross, is a Gothic cross in the form of the letter Y that is also known as a crucifixus dolorosus, furca, ypsilon cross, Y-cross, robber's cross or thief's cross.
Furcacauda is a genus of thelodontid agnathan from the Lower Devonian of Canada, and is the type genus of the order Furcacaudiformes. [2] Furcacaudiform thelodontids were deep water jawless vertebrates with symmetrical fork and lobed-finned tails and scales smaller than typical loganellid and nikoliviid thelodonti scales. [1]
From left to right: dessert fork, relish fork, salad fork, dinner fork, cold cuts fork, serving fork, carving fork. In cutlery or kitchenware, a fork (from Latin: furca 'pitchfork') is a utensil, now usually made of metal, whose long handle terminates in a head that branches into several narrow and often slightly curved tines with which one can spear foods either to hold them to cut with a ...
Also called functionalism. The Darwinian view that many or most physiological and behavioral traits of organisms are adaptations that have evolved for specific functions or for specific reasons (as opposed to being byproducts of the evolution of other traits, consequences of biological constraints, or the result of random variation). adaptive radiation The simultaneous or near-simultaneous ...
