There is ample undisputed evidence that evolution occurred. Life evolved from water billions of years ago. Early hominids emerged about 3.5 million years before Christ was born. About 1.8 million years ago, one branch of the evolutionary tree of hominids evolved into Homo erectus, one of our ancient ancestors.
From Homo erectus, Homo sapiens evolved about 300,000 years ago. However, 60,000 years ago, because of Adam, who helped introduced art and languages, Homo sapiens became smarter. There is also compelling proof Scientific Adam emerged during this period and fathered all human beings today.
Now comes the part; how did Adam’s descendent multiply? Was Eve Adam’s wife? Did Adam and Eve produce offspring that marry one another? How did six billion people on earth carry the gene of Scientific Adam?
The descendants of Adam and Eve, according to the scripture.
Many Jews, Christians, and Muslims believed Adam and Eve were the first humans to be placed on earth. The People of the Book also believed that Adam and Eve directly came from heaven. According to the Abrahamic religions’ creation myth, Adam and Eve were the first man and woman. They are central to the belief that humanity is a single family, with everyone descended from a single pair of original ancestors.
Genesis gives Adam and Eve three children, named Cain, Abel, and Seth. They gave a genealogy tracing the descendants of Cain in Genesis 4, while the line from Seth down to Noah appears in Genesis 5.
By tracing the DNA patterns found in people throughout the world, some geneticists have now identified lineages descended from 10 sons of a genetic Adam and 18 daughters of Eve.
In the Book of Genesis, God also commanded Adam and Eve to “be fruitful and multiply and fill the earth and subdue it.” So Adam and Eve produced children that mated with each other. According to the Bible, the direct descendent of Adam, Cain, firstborn son of Adam and Eve, murdered his brother Abel (Genesis 4:1–16) and thus was responsible for the first human bloodshed.
The procreation of the hominid species
Neanderthals coexisted with modern humans thousands of years ago. Multiple studies had shown there is a significant overlap between Neanderthal and human DNA. Most modern people have a small percentage of Neanderthal DNA.
Scientists believed that Homo sapiens not only fought Neanderthal but also mate with each other. As Homo sapiens and Neanderthal cross-bred, their relationship introduced even more Neanderthal DNA into the modern human genetic pool. However, thirty thousand years ago, Neanderthal vanished.
One reason suspected, interbreeding doesn’t benefit the Neanderthal. According to Fernando Mendez, a population geneticist, the Neanderthal Y chromosome was not wholly compatible with the Homo sapiens Y chromosome. As a result, if a male Neanderthal procreates with a Homo sapiens female, pregnancy will cause miscarriage. The Homo sapiens female would trigger an immune response if she became pregnant.
Since only the Homo sapiens Y chromosome survived if they interbreed with Neanderthal females, eventually, Neanderthal became extinct as inter-breeding continued, finally absorbing the Neanderthal into the Homo sapiens group. The Y chromosome is like a father’s surname. Homo sapiens will continue to pass their Y chromosome to their subsequent generations, while the Neanderthal Y chromosome will eventually disappear.
Homo sapiens also interbred with the Denisovans. The Denisovans or Denisova hominins are an extinct species or subspecies of archaic humans that ranged across Asia during the Lower and Middle Paleolithic.
Denisovans, known from few remains, mostly comes from DNA evidence. The Denisovans lived 30,000 to 50,000 years ago. Scientists found traces of Denisovans ancestors among modern Melanesians, Han Chinese, and Tibetans.
Sharon Browning, research professor of biostatistics at the University of Washington, School of Public Health, and her colleagues assume modern humans mixed with the Denisovans shortly after migrating out of Africa 50,000 years ago.
Scientists have collected evidence for years that modern humans interbred with our ridge-browed Neanderthal ancestors in Eurasia. But in Africa, where the Homo sapiens species is said to have emerged, these scientists wondered how Homo sapiens beat out not only the Neanderthals but also the other archaic species like Homo habilis and Homo erectus.
Michael Hammer from the University of Arizona provided evidence that Homo sapiens interbred with several species of hominids across the African continent and doing it so often. “We think there were probably thousands of interbreeding events. It happened relatively, extensively, and regularly,” said Hammer.
For me, I am not sure whether Adam and Eve came directly from heaven and place on earth. But if they do, I am not prepared to believe their direct descendants married their siblings because incest and inbreeding would be destructive for human survival.
According to Wikipedia, “Inbreed is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. By analogy, the term is used in human reproduction but more commonly refers to the genetic disorders and other consequences that may arise from the expression of deleterious or recessive traits resulting from incestuous sexual relationships and consanguinity. This usually leads to at least temporarily decreased biological fitness of a population (called inbreeding depression), which is its ability to survive and reproduce.”
The most likely scenario is one of the Homo sapiens, descendent from the evolved hominids, received knowledge and authority from God. He is the first viceroy called Adam.
However, Eve could be the female companion or one of the female companions of Adam. Probably, Eve could be a metaphorical reference to Homo sapiens women. What happened is Adam and Eve’s descendants did not marry their siblings. Instead, their descendent cohabited with other hominid species surrounding them in Africa.
Since Adam had a superior Y chromosome, his gene survived when his descendent mated with other female hominids. In contrast, the male hominids (other than Hom sapiens) could not produce successful offspring if they bred Adam’s female descendent.
After several generations, only the descendent of Adam survived in Africa, while the rest of the hominids became extinct. Several generations later, Adam’s descendent came out of Africa and encountered the Neanderthal and the Denisovans.
As the Homo sapiens intermingled with the Neanderthal and Denisovans, these hominids that had survived hundreds of thousands of years also faced the same fate as their hominids counterparts in Africa. They, too, faced extinction. Only Adam’s gene, the Y chromosome, survived, and we, the human race today, have it with us.
Jason paused for a while because he hesitated. Then he continued. “Well! The Bible mentioned that Adam and Eve multiplied. But I assure you his children did not marry among themselves. Instead they married the other humans who’d evolved!”
“This is outrageous, Mr.Bryden! You are blasphemous!” Dr. Clark shouted at the top of his voice.
The students were taken by surprise with Dr. Clark’s reaction but soon joined him to condemn Jason.
