Introduction

What are species anyway, and how do new ones evolve?

Here, you can explore different ways to define a species and learn about the various processes through which speciation can occur. This section also addresses the topics of cospeciation - when two lineages split in concert with one another - and modes of speciation that are specific to plants.

Let's start by defining a species.
