A well-developed theory of evolutionary biology requires understanding of the origins of life on Earth. However, the initial conditions (ontology) and causal (epistemology) bases on which physiology proceeded have more recently been called into question, given the teleologic nature of Darwinian evolutionary thinking. When evolutionary development is focused on cellular communication, a distinctly different perspective unfolds. The cellular communicative-molecular approach affords a logical progression for the evolutionary narrative based on the basic physiologic properties of the cell.Critical to this appraisal is recognition of the cell as a fundamental reiterative unit of reciprocating communication that receives information from and reacts to epiphenomena to solve problems. Following the course of vertebrate physiology from its unicellular origins instead of its overt phenotypic appearances and functional associations provides a robust, predictive picture for the means by which complex physiology evolved from unicellular organisms. With this foreknowledge of physiologic principles, we can determine the fundamentals of Physiology based on cellular first principles using a logical, predictable method. Thus, evolutionary creativity on our planet can be viewed as a paradoxical product of boundary conditions that permit homeostatic moments of varying length and amplitude that can productively absorb a variety of epigenetic impacts to meet environmental challenges.

生命是由环境决定的



完善的进化生物学理论需要了解地球上生命的起源。然而,考虑到达尔文进化思想的目的论本质,生理学发展的初始条件(本体论)和因果关系(认识论)基础最近受到质疑。当进化发展集中于细胞通信时,就会出现截然不同的观点。细胞通讯分子方法为基于细胞基本生理特性的进化叙述提供了逻辑进展。这种评估的关键是认识到细胞是往复通讯的基本重复单位,它从副现象接收信息并对副现象做出反应。解决问题。追踪脊椎动物生理学的单细胞起源过程,而不是其明显的表型外观和功能关联,为复杂生理学从单细胞生物进化的方式提供了可靠的预测图景。有了对生理原理的预知,我们就可以使用逻辑的、可预测的方法,根据细胞第一原理确定生理学的基础知识。因此,我们星球上的进化创造力可以被视为边界条件的矛盾产物,边界条件允许不同长度和幅度的稳态时刻,可以有效地吸收各种表观遗传影响以应对环境挑战。
