The effects of radiation from the young Sun and galactic cosmic rays on the physical conditions on the early Earth are significantly underestimated in studies of the problems related to the origin and evolution of the biosphere. This review considers the dynamics of solar and galactic processes over the 4.56 billion years of the existence of the Solar System. These factors substantially affected the development of adaptive technologies in ancient and modern living systems. The features of biosphere development are considered for the early Earth under the young Sun, which was fainter, but more flare active. The radiation spectrum of the young Sun is discussed together with the paradoxical mismatch between the solar radiation spectrum and the chlorophyll adsorption spectrum. Ways of solving the paradox are proposed. The role of solar radiation is important when studying models of the early biosphere of the Earth and hypothetical biospheres of giant planet satellites and exoplanets.

银河因素、年轻的太阳、地球和生命系统的生物物理学

在与生物圈起源和演化相关的问题的研究中，来自年轻太阳的辐射和银河宇宙射线对早期地球物理条件的影响被大大低估了。这篇综述考虑了太阳系存在 45.6 亿年间太阳和银河过程的动力学。这些因素极大地影响了古代和现代生活系统中适应性技术的发展。考虑到年轻太阳下早期地球的生物圈发展特征，它较暗，但耀斑更加活跃。讨论了年轻太阳的辐射光谱以​​及太阳辐射光谱和叶绿素吸附光谱之间的矛盾失配。提出了解决悖论的方法。
