Overview
A recent episode of The Why Files revisits morphic resonance, a hypothesis that proposes a non‑genetic, species‑wide “memory” enabling the rapid transmission of learned behaviors and structural information. The video, circulating on #ufotwitter and other fringe‑science forums, frames the theory as a challenge to conventional materialist biology while presenting a mixture of historical experiments, anecdotal observations, and contemporary commentary from its most vocal advocate, Rupert Sheldrake.
Historical Roots and Early Experiments
The segment begins by contextualising morphic resonance within the long‑standing debate over Lamarckism—the idea that traits acquired during an organism’s life can be inherited. Although modern genetics largely displaced Lamarckian thinking, the video highlights the 1920s McDougall rat experiments at Harvard, where psychologist William McDougall reported that successive generations of Wistar rats learned a water‑maze task increasingly faster, dropping from 165 attempts in the first generation to just 20 by the 30th. A subsequent “global replication” by geneticist F.A.E. Crew (Edinburgh) and chemist W.E. Agar (Melbourne) allegedly reproduced the effect with unrelated rat colonies, leading the presenters to suggest that information may have propagated through a shared biological field rather than through DNA alone.
“The rats seemed to know the solution before any individual could have learned it,” the video quotes a contemporary observer, underscoring the perceived anomaly.
Natural Phenomena Cited as Evidence
The documentary cites two classic cases that have been invoked in support of morphic resonance. First, British blue tit populations in the 1920s learned to pierce foil milk‑bottle caps to access cream; the behavior re‑emerged instantly after a wartime hiatus when foil became available again, despite a generation of birds never having witnessed the trick. Second, the crystallisation of glycerol and xylitol—compounds long considered “uncooperative”—suddenly became routine after a single laboratory succeeded, prompting some researchers to argue that the molecular “field” had been altered globally. While skeptics attribute the latter to the spread of seed crystals via traveling scientists, proponents of the theory view it as a manifestation of a collective molecular memory.
Sheldrake’s Formulation and the Scientific Response
Rupert Sheldrake, a Cambridge‑trained biochemist, synthesised these observations into the concept of morphic fields—habit‑forming patterns that shape the development of organisms, crystals, and even social behaviours. He argues that as more members of a species acquire a skill, the “habit” becomes entrenched, making subsequent learning easier; he points to
