One of the problems I have with the Adam and Eve story is where do Neanderthals fit in? I’ve done DNA testing at the National Geographic Society’s Genographic Project, and they determined that 2.1% of my genome was composed of Neanderthal DNA which shows that some of my distant ancestors were Neanderthals. Most people with ancestors outside of Africa have some Neanderthal DNA showing that humans interbred with the Neanderthals. So were both the Neanderthals and the Homo sapiens sapiens (humans) descended from Adam and Eve?
In addition, the recent fossil finds indicate that other possible species, currently being analyzed, interbred with Neanderthals. Then there are our chimp cousins. What all this tells us is that vertebrates share some similar genes. Thus, it is quite reasonable that the descendants of Adam and Eve, the original human vertebrates, would have similar genes as some other functioning vertebrates. We should consider the nature of matter when talking about our own decomposing anatomy.
At the same time, the Catholic Church teaches that " it is because of its spiritual soul that the body made of matter becomes a living human body; spirit and matter, in man, are not two natures united, but rather their union forms a single nature." (Information source. Genesis 1: 26-27;
CCC 364-366)
Because of the argument (degrees vs. difference in kind) over the intellective difference between a true human and similar decomposing anatomies, I do not formally speculate about the other highly sentient distinct species. Yes, I know that paleoanthropologists are in agreement with the artifacts; however, this cranky granny wants more substantial evidence which, by the way, is difficult to find going millions of years backwards. Thus, I do not venture to date the first appearance of the first two sole real truly-complete humans lovingly known as Adam and Eve. I cannot honestly answer the question about the exact nature of Neanderthals.
Also the Genesis stories seems rather confuses. In Genesis 1:24-26, God created animals first and then He created man:
But Genesis 2: 15-19 says that God created man first and then created animals:
These two version of creation cannot both be true. So why should we believe either one?
The first thing to do is to study the dramatic shift from Genesis 1: 25 to Genesis 1: 26.
The author of the first three chapters of Genesis is not a Ph.D. scientist. Yet, in a sense, he followed the scientific (inductive) method which starts with the principle – observe without prejudice. Genesis 2: 20 reflects the rational intelligence of the first human. Do I dare say that Genesis 2: 20 is also basic biological science?
The amazing shift from Genesis 1: 25 to Genesis 1: 26 calls for multiple views of human nature. To do this, the author chose to use Genesis 1: 24 as a base for comparing animal nature with human nature. Because of the obvious significance of Genesis 1: 28, the exact order in creation took a back seat similar to the beginning verses trying to describe a universe that was wonderful beyond words.
