There is nothing more interesting to humans than the story of their origins. The evolutionary process of a tree-dwelling ape becoming a walking, talking man who has developed the technology to walk on the moon, transplant hearts, or modify living things is no trivial story. This book provides a fascinating and comprehensive view of what science has learned of human evolution. This volume covers the evolution of man from tree-dwelling ape in easy-to-read language, taking complex, jargon-filled material and extracting the core information. Each of the 40 chapters covers a topic broad enough and complex enough to deserve a book of its own, but the author extracts the essence of the topic and coveys it in an elegant manner.

Down from the Trees: Man’s Amazing Transition from Tree-Dwelling Ape Ancestors approaches the subject of human evolution from three different disciplines: fossil evidence and its interpretation, evolutionary theory and its applicability, and genetic evidence and its ability to unlock prehistoric information. The third discipline has advanced unbelievably in the last few years, and this book includes the most up-to-date research.

The book is certain to be of interest to curious intelligent readers. This book would be ideal as a supplementary book in anthropology classes. An instructor’s manual is available for faculty. Students can learn about the long evolutionary path leading from tree-dwelling ape to modern human with relatively easy reading compared to typical textbooks. That journey begins when our ancestral apes came down from the trees. An instructor’s manual is available for faculty.

Key features:

  • covers the evolution of man from tree-dwelling ape in easy-to-read language, taking complex, jargon-filled material and extracting the core information
  • includes the most up-to-date information on this topic

About the Authors / Editors:
Ralph D. Hermansen
Former Senior Scientist, Hughes Aircraft Company

Ralph D. Hermansen, a graduate chemist by education, had a 40-year career in materials science and engineering. He moved around a bit in his early career in order to broaden his experience and knowledge. Ralph liked multidisciplinary projects that were at the leading edge of technology. Consequently, he has worked on the design of an atom smasher, on classified weapons programs, on design of the Boeing 737 and 747 airplanes, on military aircraft and their electronic platforms, on space satellites, on missiles, on automotive electronics, on telephony and other commercial applications. He planted his roots with Hughes Aircraft Corporation in his later career and eventually retired from there as a Senior Scientist. Concurrent to his daytime job at HAC, he was an instructor for their off-hour classes, teaching Pascal programming and Materials Engineering. Career-wise, he has contributed numerous technical articles to journals and magazines, has 21 patents, and has two published books related to his career field. The most recent is Polymeric Thermosetting Compounds, available from Apple Academic Press. This unique book is about the art and science of custom formulating adhesives, encapsulants, castings, coatings, et al. toward a specified set of property goals.

Ralph adopted a second career path after retiring in 1998, that of multidisciplinary science writer. His primary focus has been evolutionary science, which is incredibly diverse. Anthropology was his favorite subject at the University of New Mexico in the 1960s, but he stayed with materials science/engineering as a surer path to feeding his growing young family. However, New Mexico and the surrounding area are rich in prehistoric sites. Ralph loved to visit Frijoles Canyon, Chaco Canyon, Aztec, and Mesa Verde to inspect the cliff dwellings of the long gone Anasazi. Years before writing Down from the Trees, Ralph had been filling his bookshelves with books on evolutionary topics. He used these sources to research and compose articles on selected aspects of evolution. He exchanged these thoughts with the late author Elaine Morgan through correspondence for years. Human evolution has become controversial when it really need not be. Ralph’s goal in writing Down from the Trees was to help curious readers learn the facts in plain language without battling the jargon, realize that the evidence is overwhelming, see that our prehistoric past is fascinating and filled with unsolved puzzles, and realize that they can join in the fun of interpreting the new clues being constantly discovered.
