## TL;DR

This paper explores why consciousness evolved, focusing on the adaptive functions it might serve in certain species like humans.

## Contribution

It introduces a special issue compiling insights from 28 scholars to address the evolutionary purpose of consciousness.

## Key findings

- The paper highlights a gap in consciousness studies regarding its evolutionary functions.
- It proposes a theoretical framework to explore potential adaptive roles of consciousness.
- It summarizes contributions from multiple experts on this central question.

## Abstract

Why did consciousness evolve? Assuming that some species (e.g. humans) have consciousness and others (e.g. redwoods or mushrooms) do not, what problem(s) did consciousness evolve to solve? From a biological and evolutionary viewpoint, and regardless of which species have consciousness (or to what degree), this question of the adaptive function(s) of consciousness is central. Nonetheless, the growing discipline of consciousness studies has not yet fully engaged with this issue. The current special issue aims to help fill this important gap in the literature with contributions from 28 noted scholars in the field. In this introduction, we discuss basic terminological issues and potential pitfalls, provide a broad theoretical framework, consider some of the many possible answers to this central question and offer brief summaries of the included papers.

This article is part of the theme issue ‘Evolutionary functions of consciousness’.
