Speciation is the process of formation of new species. Reproductive isolation is essential as it prevents gene - flow between populations, allowing them to diverge genetically and form new species. Polyploidy can cause speciation but is not always necessary. Geographic isolation can lead to speciation but is not a must - have condition. Hybridization can sometimes blur species boundaries rather than being a necessary condition for speciation.
