This is a book following Richard Dawkins' "The Selfish Gene." It is out of print and currently a rare book that is difficult to obtain. Based on a quick inspection, there are no markings, etc., but as it is a used and old item, there is some noticeable soiling and wear on the top, bottom, and edges. Please refrain from purchasing if you are looking for a pristine item. - Author: R. Dawkins - Title: The Extended Phenotype - Translators: Toshitaka Hidaka, Chie Endo, Jiro Fujita - ISBN: ISBN4-314-00485-1 Thank you for looking.
