The fossil record includes well documented examples of both phyletic gradualism and punctuational evolution. [17] As such, much debate persists over the prominence of stasis in the fossil record. [18] [19] Before punctuated equilibrium, most evolution biologists considered stasis to be rare or unimportant.
Stasis is a procedure by which a speaker poses questions in order to clarify the main issues and persuasive points of a speech or debate. [11] This procedure allows the speaker to critically question each point, assessing the relative worth of each point as appropriate to the substance of the case and to its capacity to persuade an audience.
Cytostasis (cyto – cell; stasis – stoppage) is the inhibition of cell growth and multiplication. Cytostatic refers to a cellular component or medicine that inhibits cell division and induce cell death. [1] [2] Cytostasis is an important prerequisite for structured multicellular organisms. Without regulation of cell growth and division only ...
Stasis [2] The first category, alterations in normal blood flow, refers to several situations. These include venous stasis, long surgical operations, prolonged immobility (whilst on a long plane or car ride, bed bound during hospitalization), and varicose veins. The equivalence of Virchow's version and the modern version has been disputed. [5]
Other examples of living fossils are single living species that have no close living relatives, but are survivors of large and widespread groups in the fossil record. For example: Ginkgo biloba; Syntexis libocedrii, the cedar wood wasp; Dinoflagellates (typified on coccoid dinocysts: occasionally calcareous cell remnants)
Isostasy (Greek ísos 'equal', stásis 'standstill') or isostatic equilibrium is the state of gravitational equilibrium between Earth's crust (or lithosphere) and mantle such that the crust "floats" at an elevation that depends on its thickness and density.
The word hemostasis (/ ˌ h iː m oʊ ˈ s t eɪ s ɪ s /, [1] [2] sometimes / ˌ h iː ˈ m ɒ s t ə s ɪ s /) uses the combining forms hemo-and -stasis, Neo-Latin from Ancient Greek αἱμο-haimo-(similar to αἷμα haîma), meaning "blood", and στάσις stásis, meaning "stasis", yielding "motionlessness or stopping of blood".
Stasis (from Greek στάσις "a standing still") may refer to: A state in stability theory , in which all forces are equal and opposing, therefore they cancel out each other Stasis (political history) , a period of civil war within an ancient Greek city-state
