(n.) The act of unfolding or unrolling; hence, in the process of growth; development; as, the evolution of a flower from a bud, or an animal from the egg.
(n.) A series of things unrolled or unfolded.
(n.) The formation of an involute by unwrapping a thread from a curve as an evolute.

(n.) A prescribed movement of a body of troops, or a vessel or fleet; any movement designed to effect a new arrangement or disposition; a maneuver.
(n.) A general name for the history of the steps by which any living organism has acquired the morphological and physiological characters which distinguish it; a gradual unfolding of successive phases of growth or development.
(n.) That theory of generation which supposes the germ to preexist in the parent, and its parts to be developed, but not actually formed, by the procreative act; -- opposed to epigenesis.
(n.) That series of changes under natural law which involves continuous progress from the homogeneous to the heterogeneous in structure, and from the single and simple to the diverse and manifold in quality or function. The pocess is by some limited to organic beings; by others it is applied to the inorganic and the psychical. It is also applied to explain the existence and growth of institutions, manners, language, civilization, and every product of human activity. The agencies and laws of the process are variously explained by different philosophrs.

(9) This situation highlights the potential importance of molecules with different inheritance patterns in elucidating complex cases of reticulate evolution.
(10) The evolution of tissue damage in compressive spinal cord injuries in rats was studied using an immunohistochemical technique and by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis.
(11) Republican presidential hopeful Scott Walker has refused to say whether he believes in the theory of evolution, arguing that it is “a question a politician shouldn’t be involved in one way or the other”.
(12) It is mentioned that the lack of a valuable status for industrial physicians may adversely affect the evolution of training programs in Switzerland.
(13) Assessment of a predictive factor for the evolution of the disease is not yet possible.
(14) These studies indicate that, in three models of acute liver injury, the net influx of calcium across the plasma membrane is increased early in the evolution of the injury before irreversible damage occurs.
(15) The strong homology of mammalian L27' to yeast L29 suggests a function which has been conserved throughout evolution, and thus L27' may also be involved in peptidyl transferase activity.
(16) The diversity of the non-Hodgkin's groups, the continued evolution of histopathologic classifications, and the great frequency of advanced disease in the lymphocytic subgroups make the Ann Arbor classification of only limited value for the non-Hodgkin's lymphomas.
(17) We show how this model would explain the perinatal or infantile onset of the disease, the variability of the rate of evolution between the different SMA forms, and the fact that motoneuron loss is much more dramatic in SMA than in even advanced cases of myopathy.
(18) Evolution into acute myeloid leukemia occurred in 11 patients.
(19) On evaluation of the time evolution of the symptoms we found that most patients continued to show them until September each year.
(20) The evolution with time of cardio-respiratory variables, blood pressure and body temperature has been studied on six males, resting in semi-nude conditions during short (30 min) cold stress exposure (0 degree C) and during passive recovery (60 min) at 20 degrees C. Passive cold exposure does not induce a change in HR but increases VO2, VCO2, Ve and core temperature Tre, whereas peripheral temperature is significantly lowered.
Evolutionism
Definition:
(n.) The theory of, or belief in, evolution. See Evolution, 6 and 7.
Example Sentences:
