As true of my other books, each foreign publisher releasing this book in translation designs its own cover, without input from me. These covers offer interesting insights into national differences in public attitudes about sex.

The editions with the most schematic, least sexual covers are those for Indonesia, Japan, Korea, Slovakia, and Turkey. The American covers have also been rather restrained. It is neither pornographic, nor a how-to-do-it manual, but a humorous and scientific account of why human sexuality is so bizarrely unusual by the standards of other animal species. I provide links to my book’s Table of Contents and part of its preface, to give readers a sense of both the public interest and the scientific interest of my book’s contents. If your dog had your brain and could speak, and if you asked it what it thought of your sex life, you might be surprised by its response. Those disgusting humans have sex any day of the month! John is eager for sex all the time, without caring whether his efforts could result in a baby or not.

In everyday usage, “theory” often refers to a hunch or a speculation. When people say, “I have a theory about why that happened,” they are often drawing a conclusion based on fragmentary or inconclusive evidence.

The formal scientific definition of theory is quite different from the everyday meaning of the word. It refers to a comprehensive explanation of some aspect of nature that is supported by a vast body of evidence. Many scientific theories are so well-established that no new evidence is likely to alter them substantially. One of the most useful properties of scientific theories is that they can be used to make predictions about natural events or phenomena that have not yet been observed. For example, the theory of gravitation predicted the behavior of objects on the moon and other planets long before the activities of spacecraft and astronauts confirmed them. In science, a “fact” typically refers to an observation, measurement, or other form of evidence that can be expected to occur the same way under similar circumstances. However, scientists also use the term “fact” to refer to a scientific explanation that has been tested and confirmed so many times that there is no longer a compelling reason to keep testing it or looking for additional examples.

In that respect, the past and continuing occurrence of evolution is a scientific fact. From Science, Evolution, and Creationism, National Academy of Sciences and Institute of Medicine.

The Theory of Evolution is not a scientific law or a law of biology. Failure to meet only one challenge proves the law is wrong. This web page will prove that the Theory of Evolution fails many challenges, not simply one. This is why it is called a theory, instead of a law. The process of natural selection is not an evolutionary process. The DNA in plants and animals allows selective breeding to achieve desired results.
