Since the time of Darwin, scientists have been grappling with the challenge of reconciling the evolution of biological forms within a universe governed by fixed laws. These laws establish the foundation for the origin of life, evolution, human culture, and technology as dictated by the boundary conditions of the universe. However, these laws are unable to predict or explain the emergence of these complex phenomena. In contrast, evolutionary theory operates in the opposite direction by elucidating how selection can account for why certain things exist while others do not. To comprehend how open-ended forms can arise in a forward-process from physics without any inherent design, a fresh approach is required to understand the transition from non-biological to biological systems. This paper introduces Assembly Theory (AT), which offers an explanation and quantification of the emergence of selection and evolution. In AT, complexity of an observable object is measured using its Assembly Index (a), which represents the minimum number of steps needed to construct that object from basic building blocks. By combining a with copy number, a new quantity called Assembly is defined to quantify the amount of selection necessary for producing a given ensemble of objects. The study delves into exploring internal structure and properties of assembly space while quantifying both undirected exploratory processes and directed processes arising from selection. The implementation of assembly theory enables quantification at any scale regarding how selection emerges in physical systems as they transition from undirected-discovery dynamics to selected processes within assembly space. This mechanism provides insights into understanding when and how selection and evolution begin ultimately leading to a formal approach for defining life. One significant advantage offered by assembly theory is its ability to easily calculate and measure object assembly; this allows for quantifying a lower limit on amount of selection and memory required to generate complexity uniquely associated with biology in our universe. Overall this research presents Assembly Theory as novel framework that sheds light on how selection and evolution emerge in physical systems; it provides deeper understanding on transition from non-biological to biological systems offering formal approach for defining life.
Scientists have been trying to understand how living things change over time and fit into the rules of the universe. Evolutionary theory helps explain why some things exist and others don't by looking at how they are chosen. Assembly Theory is a way to explain and measure how selection and evolution happen. Complexity means how complicated something is, and it can be measured using the Assembly Index, which tells us how many steps it takes to make something from basic parts. The study looks at the inside of things and how they work, measuring processes that happen by chance or on purpose because of selection. Assembly Theory helps us understand when and how selection and evolution start, which helps us define what life is. It also makes it easier to calculate and measure how things are put together, giving us an idea of how much selection and memory are needed for life in our universe."

Understanding the Emergence of Selection and Evolution: Introducing Assembly Theory
Since the time of Darwin, scientists have been trying to reconcile evolution with physical laws that govern our universe. While these laws form the basis for life, evolution, human culture and technology, they are unable to explain or predict the emergence of complex phenomena. In contrast, evolutionary theory provides an explanation as to why certain things exist while others do not by elucidating how selection works. To comprehend how open-ended forms can arise from physics without any inherent design, a new approach is needed to understand the transition from non-biological to biological systems. This paper introduces Assembly Theory (AT), which offers an explanation and quantification of the emergence of selection and evolution in physical systems.
Quantifying Complexity with Assembly Index (a)
In AT, complexity of an observable object is measured using its Assembly Index (a). This index represents the minimum number of steps needed to construct that object from basic building blocks. By combining a with copy number, a new quantity called Assembly is defined in order to quantify the amount of selection necessary for producing a given ensemble of objects.
Exploring Internal Structure and Properties
The study delves into exploring internal structure and properties within assembly space while quantifying both undirected exploratory processes and directed processes arising from selection. The implementation of assembly theory enables quantification at any scale regarding how selection emerges in physical systems as they transition from undirected-discovery dynamics to selected processes within assembly space; this mechanism provides insights into understanding when and how selection begins leading ultimately towards defining life formally.
Advantages Offered by Assembly Theory
One significant advantage offered by assembly theory is its ability to easily calculate and measure object assembly; this allows for quantifying a lower limit on amount of selection required for generating complexity uniquely associated with biology in our universe. Overall this research presents Assembly Theory as novel framework that sheds light on how selection and evolution emerge in physical systems; it provides deeper understanding on transition from non-biological to biological systems offering formal approach for defining life.
Since the time of Darwin, scientists have struggled to reconcile the evolution of biological forms in a universe determined by fixed laws. These laws underpin the origin of life, evolution, human culture and technology, as set by the boundary conditions of the universe, however these laws cannot predict the emergence of these things. By contrast evolutionary theory works in the opposite direction, indicating how selection can explain why some things exist and not others. To understand how open-ended forms can emerge in a forward-process from physics that does not include their design, a new approach to understand the non-biological to biological transition is necessary. Herein, we present a new theory, Assembly Theory (AT), which explains and quantifies the emergence of selection and evolution. In AT, the complexity of an individual observable object is measured by its Assembly Index (a), defined as the minimal number of steps needed to construct the object from basic building blocks. Combining a with the copy number defines a new quantity called Assembly which quantifies the amount of selection required to produce a given ensemble of objects. We investigate the internal structure and properties of assembly space and quantify the dynamics of undirected exploratory processes as compared to the directed processes that emerge from selection. The implementation of assembly theory allows the emergence of selection in physical systems to be quantified at any scale as the transition from undirected-discovery dynamics to a selected process within the assembly space. This yields a mechanism for the onset of selection and evolution and a formal approach to defining life. Because the assembly of an object is easily calculable and measurable it is possible to quantify a lower limit on the amount of selection and memory required to produce complexity uniquely linked to biology in the universe.
