라샹프 지자기 역전
42,000년 전 지구 자기장이 붕괴했을 때, 생물학적 결과가 BERM의 자기 감수성 예측을 검증한다.
Paleomagnetic correlation
The Laschamp excursion is well-dated. The ecological consequences are temporally correlated. BERM's CRY/RPM interpretation is a hypothesis. This applies equally to conventional explanations.
THE EVENT
When the magnetic shield collapsed
Approximately 42,000 years ago, Earth's magnetic field dropped to less than 6% of its current value.
Cooper et al. (2021) dated this using New Zealand kauri trees.
They named this the 'Adams Transitional Geomagnetic Event.'
ECOLOGICAL CONSEQUENCES
A cascade of extinctions
The field minimum coincides with megafauna extinctions, Neanderthal disappearance, and vegetation shifts.
The ozone layer was significantly depleted.
BERM proposes a complementary mechanism.
BERM INTERPRETATION
Two simultaneous disruptions
The Laschamp excursion tests what happens when B_geo → 0.
Both the EM shield and CRY/RPM reference field collapse simultaneously.
Sustained circadian, melatonin, and reproductive disruption across CRY-dependent organisms.
ISS astronaut data confirms the same signature.
REPRODUCTIVE CONNECTION
Multi-generational stress
Extended B_geo collapse means sustained CRY/RPM disruption.
Multi-generational near-zero field is cumulative reproductive stress.
Falsification criteria
CRY-independent organisms should show less Laschamp stress.
The pattern should repeat at other excursions.
