Reproductive isolation, geographic isolation, or a mix of the two can lead to the formation of a new species.
Introduction. Speciation in plants and animals: pattern and process
Thus, the genetics of reproductive isolation in many plants is likely to fit the genic view of speciation (Wu 2001), which proposes that ...
Speciation – Introduction to Living Systems
Isolation of populations leading to allopatric speciation can occur in a variety of ways: from a river forming a new branch, erosion forming a new valley, or a ...

Speciation – Introductory Biology: Ecology, Evolution, and Biodiversity
Macroevolution occurs when there are enough changes in the DNA of a subpopulation of organisms along with reproductive isolation from that original population.
