A wonderful introduction to the theory of natural selection
This is an extremely well written book, combining scientific seriousness with wit and humor. It is a wonderful introduction to the theory of natural selection that gives strong insights about how and why certain traits, both physical and psychological, have been selected for our genes to be passed on from generation to generation. For psychologists in general it offers the wonderful option to solve the nature/nurture conflict. Indeed, it shows how it is the environment that selects certain genes, and then in turn how our genes can influence the environment, leading to a new selection and thus going full circle. Therefore, it becomes obvious that genes and environment are entertwined for ever, and that it is their interaction that makes us who we are. It is also a wonderful tool to understand how very complex behaviors can be executed automatically (or unconsciously), either for strategic reasons or because the number of variables to consider is way too big for our limited consciousness to grasp. Indeed, haven't you ever found yourself saying 'I am not sure why I did that...' or 'I know it was stupid but I just could not help it...'? Evolutionary psychology is trying to understand why we sometimes feel compelled to do certain things, or why we are attracted toward certain persons, even though we are not aware of the powerful forces behind our actions. Among other things, the author presents compelling evidence about why males and females are so fundamentally different psychologically, why we feel love toward our offsprings and which ones we are likely to favor over others, why and how frienships emerge, and the role of social status in the search for a mate. Additionally, one of the most impressive things I found in the book was the explanation of the emergence and purpose of feelings. Indeed, feelings seem to be so deeply routed in our animal nature that it is extremely hard, if not impossible, for us not to react in very emotional ways in many situations. Evolutionary psychology offers a logical way for us to make sense out of this fact, and provides insights about why it is such a central part of us to feel outraged, humble, grateful, indignant, proud, etc... Do not expect to feel very good about yourself after you read this book. Indeed, the author points out that the most noble behaviors emerged for a very selfish end, that is, for our genes to be passed on to the next generation. This is why the last couple of chapters are dedicated to ethics. If you ask me, this part sounds way too patronizing for my taste, and I would have been glad to draw my own conclusions about what is to be done with the knowledge I acquired reading the book. However, it is important to note that we evolved to be moral animals; that is, we became able to be aware of unconscious forces and thus to slowly learn how to master them. Finally, the author indicates that our genes were selected in what he calls the 'ancestral environment,' when we lived in small groups in a world where the word civilization did not even exist. Thus, it allows us to understand why so many people either feel out of touch with their environment or are considered deviant. In the past our genes were selected for their fitness in a particualr environment and our children were thus fit for it as well, as the environment remained virtually the same. However, in our modern world where everything is changing so fast, the genes that had been fit for hundreds of thousands of years are now lost and clueless, and our ever changing environment is leaving us no hope to ever adapt ourselves to it. It is obviously impossible to go back to our ancestral environment for our genes to feel at home again. However, we still can stop our mad race toward destruction and allow human beings to once again feel like they are belonging to this world.
