Saltation
Definition:
(n.) A leaping or jumping.
(n.) Beating or palpitation; as, the saltation of the great artery.
(n.) An abrupt and marked variation in the condition or appearance of a species; a sudden modification which may give rise to new races.
Example Sentences:

(3) The change in the orientation of pigment granule saltations following fertilization requires both a transient increase in the cytoplasmic concentration of Ca2+ and an elevation of cytoplasmic pH.
(4) Saltations in the unfertilized egg are very non-radial and are as likely to be directed toward the cortex as away.
(5) However, the appearance of saltations in such simple systems suggests that their appearance in a process as complex as biological evolution is not surprising.
