Abrupt of instantaneous speciation: It is defined as the sudden development of new species which is reproductively and ecologically isolated from the parental species. This mechanism operates through individuals and thus, not a population phenomenon.
What can result in instant speciation?
Polyploidy typically results in instant speciation—the new polyploid may be immediately isolated reproductively from its parent or parents; this process greatly increases biodiversity and provides new genetic material for evolution.
Is speciation gradual or sudden?
While some evolutionary biologists claim that speciation events have remained relatively constant and gradual over time (known as “Phyletic gradualism” – see diagram), some palaeontologists such as Niles Eldredge and Stephen Jay Gould have argued that species usually remain unchanged over long stretches of time, and …
