Final answer:
Evolutionary psychologists study how human behavior has evolved over time and its genetic basis. They would suggest that human preferences for sweet-tasting foods are genetically predisposed.
Step-by-step explanation:
Evolutionary psychologists study human behavior and how it has evolved over time. They focus on universal patterns that have been genetically determined through natural selection. In the case of human preferences for sweet-tasting foods, evolutionary psychologists would likely suggest that they are genetically predisposed. This means that our genetic makeup influences our preference for sweet foods, which may have provided an evolutionary advantage in the past.
