All the colorful life forms on earth originated from a common ancestor billions of years ago. The vitality of life and the magnificence of evolution surpass the most magnificent science fantasy and the fiction of genius writers. As Darwin praised, the endless life forms are the most beautiful and wonderful. As one of the highest unified theories of biology, the essence of evolutionary theory runs through all branches of biology. Nothing in Biology makes sense except in the light of evolution.

Evolutionary biology is a general course in life science. It helps us to understand the origin, evolution and mechanism of diversity in the biological world from the perspective of evolution, and to explore the function and reason of its connection with various disciplines of biology. During this course, together we will follow with the footsteps of Darwin and many other sages; Study the dynamics of gene frequency variation in population; master the conditions for the formation of species; understand ways of macroevolution; explore the evolution of conflict and cooperation mechanisms among individuals and species; understand the pattern and the rules of the struggle among the individuals; trace our ancestors' steps out of Africa and imagine the future of human beings and life on earth.

“Not to just admire the beauty of the flower, but to study why.” I hope you will appreciate the unity and diversity of life, feel the freshness and excitement brought by the further understanding of biological evolution, then experience the achievement of asking questions and seeking answers, and finally enjoy thinking and reasoning. Facing the complicated life world, if we can unveil the rules and logic behind it, this will expand our mental freedom and enrich the sense of well-being. In the end, welcome to communicate and interact with us and propose your valuable comments and suggestions. Let’s learn about evolutionary biology and improve our cognitive abilities.

1. Understand the status and development of evolution in biology, help students understand the origin, evolution and maintenance mechanism of the diversity of the biological world, and have a deep understanding of the role and reasons of evolutionary biology as a link between various disciplines of biology;

2. It enables students to understand the basic knowledge of evolutionary biology, achieve the advancement in learning evolutionary theory, and has rich knowledge of evolutionary biology. Then, be able to apply it flexibly in learning and research practice in other fields of biology;

3. It enables students to ask questions on abstract theoretical knowledge, forming heuristic thinking, guide students to establish a dialectical materialist view of nature from analysis and discussion, can explore the philosophy of evolutionary biology on its own, have innovative consciousness and dialectical thinking.
