Human Sexuality: Logical Fallacies and the Shotgun Aim of Arguments from Nature

Observations from nature employed to challenge a traditional model of binary human sex, fixed at conception, typically draw on the diversity of sex expression and plasticity in the animal kingdom, variable fetal developmental pathways in humans that result in intersex conditions, or purported minor sexual dimorphism in humans. This article draws attention to logical fallacies unconsciously employed when projecting observations of biological phenomena to what should be affirmed, or what is possible, for humans. A recent publication by three Christian researchers, encapsulating multiple aspects of arguments from nature, serves as an expedient example for critique.
