For example, researchers have studied physical characteristics (e.g., birth weight), demographics (e.g., birth order), psychological traits (e.g., cognitive tests), and behavioural traits (e.g., hand preference) as biomarkers because they are thought to be influenced by genes, prenatal hormones, and/or immune-mediated mechanisms involved in early brain sexual differentiation
. Various past studies of adult sexual orientation or child, adolescent, or adult gender variance have received support as models using a variety of biomarkers/proxies for sexually differentiated processes (Kishida & Rahman, 2015; Swift-Gallant, Coome, Monks, & VanderLaan, 2017, 2018).

Summary: Plato's Symposium posits a different source for human sexual drives as well as sexual differentiation
. It states that such desire stems from the fact that, in the beginning, humans beings were each as large as two are now, as round as tree trunks, with two heads and two sets of everything else: some with two sets of male members, some with two sets of female parts, others with one of each.
The book begins with a description of sexual determination and sexual differentiation
that clearly defines these terms for the reader.
