Adam and Eve

Scientists prove we all have the same mom who they call Mitochondrial Eve

Did you know scientists have actually proven that all people come from the same ancestral mother? Scientists named her Mitochondrial Eve following a study in 1987 showing all people were genetically linked to this common mother.

Basically, a person's body is made up of cells and part of each cell is called mitochondria. DNA in every other part of a cell comes from the father and mother but DNA in the cell's mitochondria comes only from the mother. Essentially each child's mitochondrial DNA matches identically with that of their mother. Well, the really cool thing is this study in 1987 found that all people have exactly the same mitochondrial DNA. This proves everybody has a common mother, whom scientists started calling Mitochondrial Eve.

Eve, of course, is the name Adam gave his wife, as Genesis 3:20 recounts, "because she was the mother of all the living." But now this makes Adam the biological father of everybody because Genesis 2:21 tells us God made Eve's body from Adam's rib.

Catholics have still another reason for knowing each person shares a common ancestry. The Church teaches mankind inherits original sin from the head of the human race, Adam. He lost sanctifying grace by sinning gravely. All of Adam's descendants, meaning everyone, would've shared in Adam's blessings without meriting it. So too they share in his punishment without meriting it personally by having first committed some mortal sin. As a result, all people are created in the state of original sin, meaning they are created without God's sanctifying presence in their souls.

Pope Pius XII flagged the unscientific theory that mankind has multiple first parents in his 1950 encyclical Humani Generis. He taught that this heresy, called "polygenism," contradicts the Catholic teaching that original sin "proceeds from a sin actually committed by an individual Adam and which, through generation, is passed on to all."
