Why was the study “Acoustic characteristics of courtship and agonistic vocalizations in Przwewalskii’s horse and in domestic horse (Alberghina et al. 2015)” carried out and what benefits has it brought to the research area?
The study in question seeks to analyse the difference between the vocalisation of 2 species of the genus Equus in order to develop a deeper understanding of morphological factors affecting the sounds the animals make which in turn may provide data that then allows further research into evolutionary divergence. The two species are very similar but are different slightly at both a physical and genetic level. These species have different chromatic numbers yet are so closely related that they can produce fertile offspring as documented by Bennett and Hoffman (1999). Domestic horses only exist as they are due to human intervention and so the divergence of domestic horses from their wild counterparts is fairly recent in evolutionary terms. This makes the study valuable not only in adding to the limited research on Przwewalskii vocalizations but also to further evolutionary biology. Equally its findings may also set a precedent for differences in vocalisations between other closely related species as referenced to in the text are studies on different animals of which some are only very distantly related to horses, even so far as to include a reference to a study on different species clownfish (Colleye et al. 2011). This essay aims to summarize and critically
