The first form of paternity testing with any kind of sound scientific basis came about in the 1920’s and was based off the recent discovery and classification of different blood types, and the fact that they were genetically inherited.

If the man had the same blood type as the kid, it stood to reason, he’s more likely to be the father than a man with a different blood type.

It’s something, but far from perfect. Tests have come quite a long way since our understanding of genetics have advanced. But no matter what science can tell us about biological parentage, there’s always going to be the much messier matter of the human emotions behind it.
