Who are we? Where are we from? These questions have troubled people for centuries. Textbooks have long taught us that human are evolved from apes. Today, a new science, Molecular Anthropology, tells us that: nearly 7 billion humans in the world share a common grand, grand...father, the Y-chromosome Adam. And they also share a common grand, grand...mother, the Mitochondrial Eve. The difference of DNA coding is only one thousandth between any persons in the world. After reading this book, you will be convinced that human could not have been the result of Evolution; Modern science has determined that hereditary information of all living species is totally defined by its own DNA coding sequences. Since biological features of all species depend on their own DNA codes, DNA codes must be the only correct direction and methodology for understanding the origin of species. In 1987, Professor Allan Wilson's research team at the UC Berkeley proposed the "Mitochondrial Eve Theory" by DNA coding that all human originated from one woman who lived about 200,000 years ago. In 1995, Drs. Dorit et. proposed the "Adam Theory" by DNA coding of Y-Chromosomal that all human originated from one man. There are two kinds of DNA encoding in our body: chromosomal DNA and mitochondrial DNA. The chromosome consists of three types: autosome, Y chromosome and X chromosome. The Eve Theory is founded on the mitochondrial DNA while the Adam Theory is founded on the Y chromosome. So what can we see from the autosome? The simple biological fact that "there are no differences between the autosomes of male and female", tells us a striking truth that is: the autosome of all men in the world must come from only one original version, and cannot be produced randomly. Therefore, the authors have established a "The only one Adam theory" by the consistent of autosomal DNA coding of men and women. All human beings on earth came from him and the earliest female ancestor came from this male ancestor. In addition, we also provide you with an answer which science cannot offer: Creationism.
