Influencias astron\'omicas sobre la evoluci\'on geol\'ogica y biol\'ogica de la tierra (Parte II)
Carlos Alberto Olano

TL;DR
This paper explores how astronomical events, such as the Sun's capture by a supercloud, influenced Earth's geological and biological evolution, including major events like glaciations and mass extinctions.
Contribution
It presents a novel hypothesis linking Earth's major evolutionary events to specific astronomical phenomena and the Sun's capture by a supercloud.
Findings
Sun was captured by a supercloud 500-700 Myr ago
Correlation between comet capture and Earth's glaciations
Association of astronomical events with mass extinctions
Abstract
With the same general purposes as Part I of this monograph, we analyze here major events in the history of the Earth, such as the formation of the Earth itself, the origin of life, the great glaciations and the mass extinctions of species, and we also analyze the astronomical context in which they occurred. We argue that the Sun was captured around 500-700 Myr ago by a supercloud, of which the Orion arm and Gould's belt are currently part, and that this event marked the history of the Earth. With this fact, we associate a massive capture of comets by the Sun, the great glaciations of the Cryogenic period, the emergence of complex life in the Cambrian and the recurrent mass extinctions of species.
