Description of The Living World 9th Edition


The Living World 9th Edition written by George B. Johnson is a great book for life and evolution studies available in ebook (PDF) free download. Biology is one of the most approachable of the sciences, yet many nonscience students look upon their first biology course with anxiety. Science courses are by their nature hard, these students believe, as they grit their teeth signing up for the course. A critical task facing any instructor, and any biology text for nonmajors, is to dispel this fear. Biology is in fact not difficult, and it is full of easy-to-grasp and fun ideas. No one who teaches biology today can fail to appreciate how important a subject it has become for our students. From global warming to stem cell initiatives to teaching “intelligent design” in classrooms, biology permeates the news and in large measures will define our students’ futures. 

What the student needs right off the bat is a window into this world he or she is about to enter. In this 9th revision of The Living World, I have set out to address this issue head-on. Relevancy is the window. Every chapter of this revision is focused directly on the relevance of its content to today’s students. When the discussion of a topic is linked to a student’s own experience, it does not seem so unapproachable, and the utility of learning it is far easier to accept.

More than most subjects, biology is at its core a set of ideas, & if students can master these basic ideas, the rest comes easy. Unfortunately, while most of today’s students are very interested in biology, the many terms get in the way, standing as a wall between students and science. With this text, I have tried to turn those walls into windows, removing those barriers so that readers can peer in and join the fun. Analogies have been my tool. I have searched for simple analogies when writing The Living World, that relate the matter at hand to things we all know. As a science, analogies are not exact, but I do not count myself compromised. Analogies trade precision for clarity.
