Darkeyeddog_data_Study1.csv from Are dark-eyed dogs favoured by humans? Domestication as a potential driver of iris colour difference between dogs and wolves
Comparative studies have shown that the eye morphology of primates has been shaped by a variety of selection pressures (e.g. communication, environmental factors). To comprehensively elucidate the complex links between ocular morphology and its evolutionary drive, attention should be paid to other p...
