Synthesized answer
The science of complexity aims to explain how intricate, organized, and adaptive large-scale behavior can arise from simple interactions among many individuals [1]. This is illustrated by examples such as how ants act with group precision, how neurons create consciousness, and how systems like the immune system or the global economy are guided [1].
To understand these complex systems, a new approach is needed that moves beyond traditional scientific reductionism and crosses disciplinary boundaries [1]. Melanie Mitchell's book offers a detailed tour of these sciences, seeking general principles that apply across biological, technological, and social phenomena [1, 2]. The passages discuss what complexity seeks to answer and how it is studied, but they do not provide an explanation of the key concepts in her own words.

From the book
Title: Complexity: A Guided Tour by Melanie Mitchell Description: What enables individually simple insects like ants to act with such precision and purpose as a group? How do trillions of individual neurons produce something as extraordinarily complex as consciousness? What is it that guides self-organizing structures like the immune system, the World Wide Web, the global economy, and the human genome? These are just a few of the fascinating and elusive questions that the science of complexity seeks to answer. In this remarkably accessible and companionable book, leading complex systems…
on its interdisciplinary strategies, Mitchell brings clarity to the workings of complexity across a broad range of biological, technological, and social phenomena, seeking out the general principles or laws that apply to all of them. She explores as well the relationship between complexity and evolution, artificial intelligence, computation, genetics, information processing, and many other fields.
