The Maya forged one of the greatest societies in the history of the ancient Americas and in all of human history. Long before contact with Europeans, Maya communities built spectacular cities with large, well-fed large populations. They mastered the visual arts, and developed a sophisticated writing system that recorded extraordinary knowledge in calendrics, mathematics, and astronomy. The Maya achieved all this without area-wide centralized control.

Brian and Deborah Charlesworth provide a clear and concise summary of the process of evolution by natural selection, and how natural selection gives rise to adaptations and eventually, over many generations, to new species. They introduce the central concepts of the field of evolutionary biology, as they have developed since Darwin and Wallace on the subject, over 140 years ago, and discuss some of the remaining questions regarding processes.

This Very Short Introduction uncovers the history of our understanding of sexual selection, from Darwin's key insights to the modern day.
