Evolution in its contemporary meaning in biology typically refers to the changes in the proportions of biological types in a population over time (see the entry on the concept of evolution to 1872 for earlier meanings). As evolution is too large of a topic to address thoroughly in one entry, the primary goal of this entry is to serve as a broad overview of contemporary issues in evolution with links to other entries where more in-depth discussion can be found. The (...) entry begins with a brief survey of definitions of evolution, followed by a discussion of the different modes of evolution and related philosophical issues, and ends with a summary of other topics in the philosophy of evolution focusing particularly on topics covered in this encyclopedia.

In this article, I explore the possibility of plant subjective awareness within the conceptual framework of Plant Neurobiology -- an emerging discipline that aims to unearth the way plants perceive and act purposefully. I shall argue that plants lack none of the functional structures that are supposedly needed, and so we have no scientific reason to exclude the possibility that they have evolved different structures that underlie their own subjective experiences.
