Understanding What a Human Being is Made Of
Biological Components: Cells, DNA, and Metabolites
A human being is fundamentally composed of various biological components. At the most basic level, our bodies are made up of cells, which are the building blocks of life. Each cell contains DNA, the genetic blueprint that dictates our biological functions and characteristics. Advances in molecular biology have allowed scientists to catalog almost all of our DNA, RNA transcripts, and proteins, which are essential for various cellular functions1.
Moreover, cells themselves are composed of even smaller parts known as metabolites. These include peptides, amino acids, nucleic acids, carbohydrates, organic acids, vitamins, and minerals. Metabolites are crucial as they serve as the building blocks for macromolecules like proteins, RNA, and DNA, essentially acting as the "bricks and mortar" of the cell1.
The Mind and Consciousness: Mental and Physical Interactions
Beyond the physical components, a human being also encompasses the mind and consciousness. The mind develops from infancy to adulthood, becoming self-aware and intelligent. This development is influenced by both genetic information and environmental factors. The concept of the "story-verse" suggests that human beings are hyperobjects that interact within an ecosystem of physical and mental representations. This ecosystem includes not only biological activities but also higher-order interactions facilitated by the nervous system2.
Integrated Components: The Self, Mind, Heart, and Body
A human being is not a single entity but a composition of several integrated components. These include the self, mind, heart, and body, each functioning independently yet harmoniously. The self can be seen as the driver, guiding the mind, heart, and body through life. This integrated system ensures that all parts work together to maintain overall well-being and functionality3.
Anthropogenic Mass: Human Impact on Earth
Interestingly, the material output of human activities, known as anthropogenic mass, has now surpassed the total living biomass on Earth. This means that the mass of inanimate objects created by humans exceeds the mass of all living things. This quantification highlights the significant impact humans have on the planet, marking a new epoch known as the Anthropocene4.
Conclusion
In summary, a human being is a complex entity composed of biological components like cells, DNA, and metabolites, as well as mental and physical interactions that form the mind and consciousness. These elements are integrated to function harmoniously, guided by the self. Additionally, the impact of human activities on Earth is profound, with anthropogenic mass now exceeding natural biomass. Understanding these components provides a comprehensive view of what makes up a human being.
