What should the average person know about science? Because science is so central to life in the 21st century, science educators and other leaders of the scientific community believe that it is essential that everyone understand the basic concepts of the most vital and far-reaching disciplines. Evolution 101 does exactly that. This accessible volume provides readers - whether students new to the field or just interested members of the lay public - with the essential ideas of evolution using a minimum of jargon and mathematics. Concepts are introduced in a progressive order so that more complicated ideas build on simpler ones, and each is discussed in small, bite-sized segments so that they can be more easily understood. Evolution 101 provides an introduction for non-scholars to this most powerful scientific theory, covering such issues as: the history of evolutionary thought, from before Darwin to the present day; the evidence for evolution, from fields as diverse as geology, molecular biology, paleontology, and more, that show how strongly supported evolution is; how evolution works, including topics ranging from behavior (e.g., sexual selection) to molecular biology (e.g., mutation); and evolution in our daily lives, including how evolution accounts for phenomena such as antibiotic resistance and pesticide resistance. This essential resource will answer the questions students and lay people have regarding evolution, and will point them on the path to further understanding.
