In biology, saltation (from Latin saltus 'leap, jump') is a sudden and large mutational change from one generation to the next, potentially causing single-step speciation.

Saltational speciation, also known as abrupt speciation, is the discontinuity in a lineage that occurs through genetic mutations, chromosomal aberrations or other evolutionary mechanisms that cause reproductively isolated individuals to establish a new species population.

Hint: Saltation is a type of sudden and large-scale mutational change from one generation to the next and has the potential of causing single-step speciation. Additionally, it was historically offered as a substitute for the theory of Darwinism.

Darwin's rejection of saltation opened a rift among biologists that hasn't healed -- right up to the present day.

Mar 16, 2025 · Saltation is the process where particles, like sand or gravel, are lifted by wind or water and then dropped back down, creating a hopping or bouncing motion. This phenomenon plays a crucial role in shaping landscapes, forming sand dunes, and even influencing riverbeds.

Saltational speciation, also known as abrupt speciation, is the discontinuity in a lineage that occurs through genetic mutations, chromosomal aberrations or other evolutionary mechanisms that cause reproductively isolated individuals to establish a new species population.

In Biology, saltation is a sudden change from one generation to the next, that is large, or very large in comparison with a usual variation of an organism. the term is used for non-gradual changes that are atypical of ,or violet- gradualism involved in modern evolutionary theory.

In biology, saltation means (from Latin, saltus, "leap") a sudden change from one generation to the next generation, that is large, or very large, in comparison with the usual variation of a living organism.

According to de Vries, saltation is a single-step large mutation that leads to speciation

Locomotion - Jumping, Leaping, Hopping: The locomotor pattern of saltation (hopping) is confined mainly to kangaroos, anurans (tailless amphibians), rabbits, and some groups of rodents in the vertebrates and to a number of insect families in the arthropods.
