Reinforcement's ubiquity is unknown, [4] but the patterns of reproductive character displacement are found across numerous taxa and is considered to be a common occurrence in nature. [18] Studies of reinforcement in nature often prove difficult, as alternative explanations for the detected patterns can be asserted.
For example, the secondary contact between Homo sapiens and Neanderthals, as well as the Denisovans, left traces of their genes in modern human. However, if hybridization is so common that the resulting population received significant amount of genetic contribution from both populations, the result should be considered a fusion.
Studies of reinforcement in nature often prove difficult, as alternative explanations for the detected patterns can be asserted. [3]: 358 Nevertheless, empirical evidence exists for reinforcement occurring across various taxa [7] and its role in precipitating speciation is conclusive. [8]
