Ovulatory egg: the origin and evolution of life

The egg is a special cell with a life cycle of only a few days, and fertilization occurs within these few days. After the egg is released from the ovary, it takes several days to reach the fallopian tube, where it combines with sperm to form a fertilized egg.

Why do we know that eggs exist? This is because early in human evolution, our ancestors obtained nutrients from insects and other small invertebrates. Among these animals, there is an animal called an egg, and the eggs they produce were used by our ancestors.

Over time, humans evolved into intelligent creatures. We began to learn to plant and hunt, and in the process learned about nutrition and the evolution of life. This knowledge lets us know that the egg is the core of our life and the source of our nutrition.

By understanding the egg, we can better understand the origin and evolution of human life.
