The origin of consciousness has come into main focus recently and is a widely discussed and controversial topic. This paper gives an overview of some of the most important theories of the origin of consciousness, including evolutionary and functional theories of consciousness emergence, theories of consciousness to be an optional extra and the idea of consciousness emergence by being not separable from higher-order functions. However, it will be shown that every theory faces its own, severe problems, which do not seem to be solvable in the near future. Furthermore, is the possibility and accessibility of non-human consciousness examined, with an emphasis on animal consciousness accessibility. It is shown that this question is also difficult to answer due to several limitations and further research is suggested.

Objectives & Research Themes
This thesis examines the origin and evolution of consciousness by reviewing major theoretical frameworks and addressing the difficulty of identifying conscious states in non-human animals. The central research objective is to investigate whether consciousness represents an evolutionary adaptation, an optional cognitive feature, or an inseparable byproduct of complex mental processes.
- Evolutionary theories and the survival benefit of consciousness
- The philosophical debate surrounding "zombies" and consciousness as an optional extra
- The hypothesis of consciousness as an inseparable byproduct of brain complexity
- Methodological challenges in evaluating self-awareness and intentionality in animals
Excerpt from the Book
1.1.2 the possibility of Darwinian evolution of consciousness by examining the question of the function of consciousness
Why is the function of consciousness important when discussing the evolution of consciousness? Well, Darwin stated that, to become an adaptation, every trait needs to have a benefit to the fitness of the individual. Therefore, to know if consciousness is an adaptation shaped by natural or sexual selection, one first needs to find the function or functions of consciousness. Several philosophers and psychologists have made an effort to find these functions of consciousness with different results.
Humphrey (1983) believes that consciousness evolved in humans because we need it to be the social creatures we are. Well-developed social structures require introspection to be able to understand, predict and manipulate other members of the group (Humphrey, 1983). A being that is conscious can make inferences about its own states, desires and motivations by using introspection (named ‘inner-eye’ by Humphrey) and can therefore function more successfully in social settings (Humphrey, 1983). Therefore, being conscious gives these individuals the advantage, of displaying superior social behaviour. As a result natural selection could have worked on consciousness to make it an adaptation. The same view is basically held by Jaynes (Crook, 1980, p. 15), who states that an increase in social complexity, with a need for analytical flexibility in interaction with members from other cultures, gave rise to consciousness.
Summary of Chapters
1. EMERGENCE OF CONSCIOUSNESS: This chapter reviews core evolutionary, functional, and philosophical theories regarding the development of conscious experience in organisms.
2. WHO AND WHAT IS CONSCIOUS?: This chapter explores the challenges of identifying consciousness in humans and animals, specifically assessing behavioral and psychological markers such as self-awareness, theory of mind, and language.

Frequently Asked Questions
What is the primary focus of this thesis?
The thesis focuses on the origin of consciousness, exploring how it may have evolved and examining various theories that attempt to explain why conscious beings exist.
What are the central themes discussed in the paper?
The core themes include evolutionary perspectives on mental traits, the philosophical mind-body problem, the feasibility of "zombies" (beings that behave like humans but lack consciousness), and the criteria for attributing consciousness to animals.
What is the research goal?
The goal is to provide a comprehensive review of major theories regarding the emergence of consciousness and to critically analyze the methods used to determine if consciousness exists in non-human species.
Which scientific approaches are utilized?
The work utilizes a combination of philosophical analysis, evolutionary biology, and psychological behavioral studies to evaluate arguments for and against different theories of consciousness.
What is covered in the main body of the work?
The main body investigates evolutionary theories (such as social complexity and expertise), the "conscious inessentialism" debate, and observational methods like mirror self-recognition and theory of mind tests in primates.
What key terms characterize the study?
Key terms include natural selection, qualia, theory of mind, functionalism, and the debate surrounding the accessibility of animal subjective experience.
What is the "zombie" thought experiment?
The zombie thought experiment posits that it is theoretically possible to have an entity that is physiologically and functionally identical to a human but lacks any internal subjective experience, challenging the necessity of consciousness.
How does the author evaluate animal consciousness?
The author discusses methods like the mirror self-recognition test and the assessment of suffering or theory of mind, noting that all these methods face significant limitations in providing definitive proof.
What is the significance of the "theory of mind"?
Theory of mind is presented as the ability to attribute mental states to others, which is argued by some as a prerequisite for the kind of consciousness experienced by adult humans.
Why is the origin of consciousness still considered an open problem?
The paper concludes that existing theories lack empirical evidence and often fail to explain the subjective nature of experience (qualia), leaving the question of its emergence currently unsolvable.
