Speciation
Evolution of new species through reproductive isolation and accumulated genetic change over long periods.
Real World
Darwin's finches on the Galápagos Islands evolved into 18 distinct species from a single ancestor, each developing different beak shapes suited to different food sources after geographic isolation on separate islands.
Exam Focus
Always state the type of speciation (allopatric, sympatric) and name the isolating mechanism to access full marks.
