Can all blood types come from Adam and Eve?
If all of humanity descended from Adam and Eve—as the Bible teaches—how is it
possible that people have different blood types today?
An answer comes from basic genetics. Unlike other traits that are controlled by
multiple genes, the A, B, and O blood types are controlled by a single gene.
However, this gene comes in three slightly different versions, known as alleles,
and that is why we have these three possible major blood types.
When God created Adam and Eve, He could have created them with great genetic
variety. This means Adam and Eve could have possessed all three alleles between
them. However, blood type O appears to be due to a mutated or damaged version of
blood type A allele, which suggests it arose later in human history. This means
Adam and Eve would only need to possess the A and B alleles between them. So the
origin of blood types is consistent with the Bible’s history.
