Which came first, the chicken or the egg?

This is an age-old question, "Which came first, the chicken or the egg?" Philosophically unsolvable, it has puzzled thinkers for centuries. I remember watching a cross talk show many years ago. The two comedians asked and answered questions, and their words were witty, which constantly aroused laughter, but in the end they still couldn’t come to a definite conclusion whether the chicken or the egg came first.

But from a biological point of view, the answer should be that the egg came first.

这是因为随着时间的推移，进化是通过动物体内遗传物质的微小、渐进的变化来进行的。在通过自然选择或人工选择后，经过一段时间后，动物的特征就会很明显。以野生的火狐狸为例，人们做过实验来去掉咬人和逃跑的野性，通过只选择野性少和对人友好的一小部分狐狸来繁殖后代。经过35代约40年的时间，家养的火狐狸就诞生了。当然从鸟进化到鸡经过了很长的时间。在很遥远过去的某个时刻，一只不完全是鸡的鸟经过遗传物质的微小变化产下了一个包含基因突变的蛋，从而产生了世界上第一只真正的鸡。这意味着第一个孵化出鸡的蛋来自一只不完全是鸡但非常非常接近鸡的鸟。

We usually think that time is an objectively existing entity that acts on everything, and it must be from the past to the future. We can only live in the present, remember the past, and look forward to the future. People would be shocked to know that time does not exist.

"The Order of Time" is a book on the philosophy of science published in 2017 by Italian theoretical physicist Carlo Rovelli. This book is about the nature of time and its different manifestations in physics, philosophy, literature and everyday life.

In the book, Rovelli first introduces the history and concept of time, and explores the performance of time in different disciplines. He talked about physicists' understanding of time, including Newton's concept of time in classical physics, space-time theory in relativity, and time evolution in quantum mechanics. At the same time, Rovelli combined the concept of time with philosophy and literature, and analyzed the importance and role of time in human culture and psychology. He delves into how humans perceive and remember time, how time is uniquely human, and how time affects our lives and behaviors.

Finally, Rovelli developed his own theory of time, arguing that time is not a static, ubiquitous entity, but is composed of physical and informational processes. He believes that the nature of time is randomness and uncertainty, which is of great significance to our understanding of the nature of the universe and its future development.

Overall, The Order of Time is a comprehensive work that explores the nature and different manifestations of time, offering new perspectives and ways of thinking that help us better understand the world around us.
