saltatory

saltatory

Saltatory evolution can lead to rapid changes in species.

Definition
  1. Adjective:
    • Relating to or involving leaping or jumping: "saltatory" describes something characterized by or pertaining to the act of jumping or moving by leaps.
    • Proceeding by abrupt changes: In biology or evolution, "saltatory" refers to development or change that occurs in sudden, discontinuous steps rather than gradual progression.
Usage Examples
  • Adjective:
    • The frog's saltatory movement allowed it to escape predators quickly. (The frog's ability to jump helped it evade danger.)
    • The theory of saltatory evolution suggests that species can change rapidly through sudden mutations. (The idea that evolution can involve abrupt leaps rather than slow, steady change.)
Advanced Usage

  • "saltatory conduction": In neuroscience, the process by which nerve impulses jump between gaps (nodes of Ranvier) along a myelinated axon, speeding up signal transmission.

    • Saltatory conduction enables rapid nerve impulse transmission in vertebrates. (The jumping of electrical signals between nodes speeds up neural communication.)

  • "saltatory locomotion": A mode of movement using jumps or hops, typical of animals like kangaroos, frogs, and grasshoppers.

    • Kangaroos rely on saltatory locomotion for efficient travel across open terrain. (They move by jumping rather than walking or running.)
Variants and Related Words

  • Saltation (noun): the act of leaping or jumping; a sudden change or mutation.

    • Saltation is a key feature of certain evolutionary theories. (Leaping or abrupt change in biological development.)

  • Saltatorial (adjective): adapted for leaping or jumping.

    • Grasshoppers have saltatorial hind legs. (Their legs are specialized for jumping.)

  • Saltatorially (adverb): in a manner involving leaping or jumping.

    • The insect moved saltatorially across the leaf. (It moved by hopping.)
Synonyms
  • Jumping: moving by sudden leaps.
  • Leaping: propelling oneself off the ground.
  • Hopping: making short, quick jumps.
  • Discontinuous: occurring in separate, abrupt steps.
Related Idioms
  • "by leaps and bounds": rapidly and significantly; making great progress.
    • The company grew by leaps and bounds after the new product launch. (It grew very quickly and dramatically.)
