Compelling affirmation has been established by researchers affiliated with Cambridge University and the Helmholtz Centre in Berlin, indicating that archaic marine life utilized magnetic guidance systems around 97 million years in the past. This finding is detailed within the journal Nature.
During their investigation, the scholars examined colossal magnetofossils—fossilized magnetite grains amounting up to 2.25 micrometers in size, recovered from abyssal sediments. This process yielded the first definitive proof that these particular formations were specialized to sense the strength of the Earth’s magnetic field.
The fossilized specimens were subjected to scrutiny using a cutting-edge procedure rooted in magnetic tomography. This advanced approach enabled an in-depth examination of their internal architectures.
It is reported that the scientists detected magnetic fields residing within the fossils, suggesting an inherent capacity for magnetoreception in these creatures. However, the specific species responsible for generating these features remains undetermined for now. The material suggests that these were likely migratory ocean dwellers, possibly including animals such as eels.
This breakthrough sheds illumination on the evolutionary trajectory of magnetoreception in fauna, illustrating the progression from rudimentary bacterial structures into sophisticated navigational architectures mirroring contemporary GPS technology.
