The Origins of Life: From the Birth of Life to the Origin of Language

Maynard Smith and Szathmáry wrote this as the accessible version of their technically demanding Major Transitions in Evolution, and it succeeds as both a standalone book and a companion to the original. The same framework applies — each major transition in the history of life involved a change in how information is stored and transmitted — but here the argument is presented with less formal apparatus and more narrative exposition. The book covers the origin of replicating molecules, the invention of the genetic code, the evolution of sex, the emergence of multicellularity, and the origin of language, treating each as a specific solution to a specific information-processing problem. The prose is remarkably clear for two authors whose primary audience was evolutionary biologists. For readers interested in the deep connection between information theory and the history of life, this is the most approachable entry point.
