Against epigenetic responsibility: The problem of causality in 'foetal programming' science

Area of Science:

• Environmental epigenetics
• Reproductive ethics
• Developmental toxicology

Background:

• Intrauterine environmental exposures may program offspring epigenetics, raising concerns about maternal moral responsibility.
• Existing proposals for maternal epigenetic responsibility often overlook the scientific uncertainty regarding causality.

Purpose of the Study:

• To evaluate the causal evidence linking intrauterine exposures to offspring epigenetic modifications and health outcomes.
• To assess whether current fetal programming research sufficiently establishes causality to ground claims of maternal moral responsibility.

Main Methods:

• Critical analysis of existing human fetal programming research.
• Examination of the challenges in establishing causal relationships in epigenetic studies.
• Philosophical inquiry into the conditions for moral responsibility.

Main Results:

• Much human fetal programming research has not yet established a definitive causal epigenetic link between intrauterine exposures and subsequent offspring health.
• Significant challenges persist in demonstrating the causal significance of prenatal exposures for long-term health outcomes.

Conclusions:

• The current lack of established causality in fetal programming research significantly weakens the argument for prospective mothers having a moral responsibility for their offspring's epigenetics.
• Further rigorous research is needed to establish causal links before moral claims can be substantiated.
