Introduction
History and Science of Cultivated Plants narrates how humans transitioned from foragers
to farmers and have arrived at present-day industrial agriculture-based civilization. It entails
myths, historical accounts, and scientific concepts to describe how human efforts have
shaped and produced easier to grow, larger, tastier, and more nutritious fruits, vegetables,
and grains from wild plants. Using examples of various economically and socially important
crops central to human civilization, the book describes the origin of crop plants, the
evolution of agricultural practices, fundamental concepts of natural selection vs.
domestication, experimental and methodical plant breeding, and plant biotechnology.
A chapter on genetically engineered crops includes the fundamental concepts of
recombinant DNA technology, the development of transgenic crops, and their societal
impacts around the globe. The book discusses the challenges of feeding the world’s
growing population in the wake of the changing climate, reduced acreage, and other socio-economic constraints, and the need for a sustainable agriculture system in the 21st century
and beyond.
This text treats science as a type of human activity and examines the nature, value, and
limitations of scientific methods and the interaction of science with society at numerous
levels. The complex interactions between the available scientific knowledge and how it
influences societal decisions have been described using a few historical examples. Often,
the issues related to science can be adequately resolved using a more objective and
systematic approach. However, the socio-political decisions have lasting consequences,
and those need to be open-ended enough to leave room for inquiry, evaluation, and
innovations. The purpose of this book is to empower its readers to adopt an open-minded
approach to science and technology in general and develop a fundamental understanding
of the agriculture and farming communities —who contribute to the variety, quality, and
quantity of foods they consume.
