Final answer:
Alfred Kinsey is the theorist who highlighted the interplay of biological and social factors in determining sexual orientation, recognizing sexuality as a continuum.
Step-by-step explanation:
The theorist who argues that sexual orientation results from the interaction of biology and the social environment is Alfred Kinsey. Kinsey recognized sexuality as a continuum and highlighted the importance of both biological and social influences in his work. His view contrasts with the notion of a simple genetic determination of sexuality, underscoring the complexity of sexual orientation.
Studies show that there is no single cause for sexual orientation, with genetic, hormonal, developmental, social, and cultural factors all playing roles. Additionally, the sociological perspective emphasizes how sexual attitudes and practices are shaped by the societal context and how these sexual behaviors are interpreted differently across cultures.
