Adam was the first man. Eve was the first woman. Before Adam and Eve 6,000 years ago, you had male and female. This actually goes back 3.5 Billion years with Pond Scum when sex began with recombination. (The term "pond scum" is a colloquial and imprecise term often used to refer to various simple aquatic organisms like algae, bacteria, and other microscopic life forms.)
- Mitochondrial Eve: Mitochondrial Eve is the most recent common matrilineal ancestor of all humans, meaning she was a woman from whom all living humans today have inherited their mitochondrial DNA. Genetic studies suggest that Mitochondrial Eve likely lived around 100,000 to 200,000 years ago.
- Y-chromosomal Adam: Y-chromosomal Adam is the most recent common patrilineal ancestor of all humans, meaning he was a man from whom all living humans today have inherited their Y chromosome. Genetic studies suggest that Y-chromosomal Adam likely lived around 200,000 to 300,000 years ago.
The archaeological and fossil record also provide evidence of early Homo sapiens and our evolutionary ancestors, dating back hundreds of thousands of years. The MRCA estimates align with the broader timeline of human evolution and the emergence of anatomically modern Homo sapiens.
The Sixth Day
…26Then God said, “Let Us make man in Our image, after Our likeness, to rule over the fish of the sea and the birds of the air, over the livestock, and over all the earth itself and every creature that crawls upon it.” 27
So God created man in His own image; in the image of God He created him; male and female He created them. 28God blessed them and said to them, “Be fruitful and multiply, and fill the earth and subdue it; rule over the fish of the sea and the birds of the air and every creature that crawls upon the earth.”…
The six 24 hour days of Genesis Chapter One results in an age of the universe from our perspective of 14 billion years [14, 000,000,000 years]. From the Bible’s perspective of time for those six evocative days of Genesis, the number of our years held compressed within each of those six 24 hour days of Genesis, starting with Day One, would be, in
billions of years, respectively, 7.1; 3.6; 1.8; 0.89; 0.45; 0.23. (23,000,000)
Each day is half the length of the day before it. So male and female were created on the sixty day. 23 million years ago. The earliest known primates appeared during the Paleocene epoch, which lasted from approximately 66 to 56 million years ago. Primates are a specific group of mammals.
Currently, the conclusion is that
all current human mtDNA originated from a single population from Africa, at the time dated to between 140,000 and 200,000 years ago. The dating for "Eve" was a blow to the multiregional hypothesis, which was debated at the time, and a boost to the theory of the recent origin model.
