Science has developed to the present, for people ourselves, there are two biggest problems that have not been resolved. They are: What are we? Where do we come from? These two questions have troubled people for centuries.

150 years ago, Charles Darwin wrote two books: "On the Origin of Species" and "The Descent of Man, and Selection in Relation to Sex". In these two books, the theory of species evolution was proposed: All spe-cies are constantly evolving; The present people and all species are formed through natural selection.

The basis of this theory is based on the comparison of biological forms. Now, knowing that all the genetic information of living things is completely determined with DNA, is evolution still correct? Had humanity evolved from apes?

This book will answer these questions.
