His father ran away from home many years ago, and with the passage of time, the traces left behind became fader and fainter, and the faces left in his memory became more and more blurred, and Chen Siping could no longer remember what kind of person he was. A thought suddenly broke into his mind, and it made his heart pound, and it might be a good idea to read through the book left by his father.

Reading is his favorite pastime, knowing his father is his desire, Chen Siping is full of expectations for the upcoming summer vacation, he feels that life is smeared with a layer of brilliant colors, like high-rise buildings in the sunset, bright but not dazzling.

Chen Siping pushed the cardboard box to the bottom of the bed, turned on the lamp and sat down at the desk, and opened the first page of "Why Are We Sick" from the beginning amid the hum of the air conditioner.

This is a popular science book that introduces "Darwin's medicine", Chen Siping reads it very hard, he understands plants, he understands insects, that is the reading capital that he has spent a lot of effort to accumulate, but these capitals do not help to understand Darwin and medicine. He felt that he needed to make up for a lot of things, and he didn't understand why his father was interested in them.

The book is not thick, and it took Chen Siping more than two weeks to read "Why Are We Sick", and memorized a stomach full of obscure special terms, and his brain was stirred into paste.

At the end of the book, he reads the second note left by his father.

"My teeth are shaky, and I am gloomy, but I still have interest and enthusiasm for reading. Reading is not for knowledge, but for recreation. It is an irrefutable fact that people walk to the grave step by step from the moment they are born, even though we are often unaware of it or deliberately ignore it. People are inherently dead, the journey is of different lengths, the scenery is different, and each road leads to the same place. In natural beings, survival and reproduction are instincts, and there is nothing else to think about. For us restless souls, outside of our instincts, we always tirelessly seek some solace, otherwise life would be too boring. Each person is a unique individual, your honey, his arsenic, behind the self-treatment of others, there is an implicit imposition of one's own will on others, which is a mistake we often make. However, there are always books that shape our minds, change our lives, are exciting, unforgettable, eager to share with others, and it is a blessing in life to meet them.

"It's a kind of luck to meet the right person at the right time, to fall in love with all your heart, whether it has a result or not. The same goes for reading. There are two books that have had a great impact on me, "Why We Are Sick" by R.M. Nice and G.C. Williams, and "Reading Biology Notes" by Zheng Yefu, which I love so much that I have read them many times. It's no exaggeration to say that these two books have shaped me and made me look at life differently than many people around me. I thank the authors, R.M. Nice, G.C. Williams, and Yefu Zheng. ”

Chen Siping felt that he had touched his father's pulse, and his decision was correct.

The joys and sorrows of the individual are insignificant, life goes on, and Surabaya City soon ushered in the much-anticipated college entrance examination. Surabaya Middle School is not the test center, the campus is half empty, and the cafeteria is not as crowded as in the past.

Someone coughed deliberately and put down the plate opposite him, Chen Siping subconsciously raised his head and saw a familiar face, unable to name it. His doubts were written on his face, so that the other party had to introduce himself, surnamed Li, Mr. Li of the biology group, who had an uncomfortable throat recently, borrowed a set of small bee megaphones from him for class. Pharyngitis is an occupational disease of teachers, and every time he lasts until the end of the term, he can't hold on, so Chen Siping readily agreed, saying that he would go to the storage room to get it after eating.

Mr. Li thanked him. It seemed a little rude to turn around and leave after saying something, so I sat down to eat and chatted casually. Chen Siping remembered "Why Are We Sick", it happened that the other party was a professional, and humbly asked, if you want to understand Darwin's theory of evolution, what book is better to read? Mr. Li was a little surprised, and after thinking about it for a while, he recommended "Why You Should Trust Darwin", and said that for ordinary readers, this book is easier to understand than "The Origin of Species".

The reference to "ordinary readers" did not make Chen Siping feel embarrassed, he felt that Mr. Li was a strict and serious person, and being his student may not be fun, but he could learn a lot.

After getting off work that day, Chen Siping couldn't wait to rush home, flipped through the books left by his father, and actually found "Why Should You Trust Darwin", written by Jerry A. Coyne. There was providence in the dark, and he was struck by an unexpected excitement, and he almost jumped up in excitement.

The book is a little too heavy, more than 300 pages, as Mr. Li said, it is not difficult for him, an "ordinary reader", to go deep and simple. Chen Siping was fascinated by the reading, as if he had pushed open a closed window and seen a completely different scenery.

At the end of the book, in the blank space, he saw his father's handwriting again.

"Why We Should Trust Darwin is a popular science book on evolutionary theory, written by Jerry A. Coyne, an American evolutionary biologist who has been a professor in the Department of Ecology and Evolutionary Chemistry at the University of Chicago for the past two decades, conducting research on evolutionary genetics. The original work "written for American readers deeply influenced by creationism", covers all aspects of evolutionary theory, the content is not obscure, on the one hand, limited by the audience, after all, ordinary readers do not have the relevant academic background, on the other hand, thanks to the fluent translation, in line with the habit of Chinese expression, the translator 'even accurately identified Coyne's clerical errors and a few inaccuracies beyond his professional knowledge', which is relatively rare.

"The book was a little too heavy, poorly bound, and crappy on paper, and it took me a few nights to read through it, déjà vu, and there wasn't much exciting new stuff, including the concept of 'genetic drift,' which I had previously read about in the book 'Ode to Difference'. I 'believed in Darwin' many years ago, and while it's not a waste of time, the book lacks some kind of 'touch' to the heart, unlike Why We Get Sick. Maybe 10 years ago, it wouldn't have been the same. It is a kind of luck to meet the right person at the right time and fall in love with all your heart, whether it is fruitful or not. The same goes for reading.

"The author lists extended readings and references at the end of the book, and unfortunately this part of the bibliography is not translated."

Chen Siping closed the last page and breathed a long sigh of relief, he had the illusion of enlightenment, after many years, he and his father were connected together through a book, which is a kind of spiritual connection, which few fathers and sons do. At the same time, he also felt deep regret that he had matured too late and could not turn back time, and that his father had left him forever.
