Why isn't the study of genes called genealogy?
Gregor Mendel's genetic studies
Well, the name was already taken.

Genealogy is the study of family origins. It is how people trace their ancestry and create a family tree. It's not a biological science. Genealogy has been around for a long, long, time — before we discovered genes.

The science of genetics began in the 1800s when Gregor Mendel figured out how traits are inherited by studying peas. Since scientists identified genes in the mid-1900s, the field of genetics has grown by leaps and bounds.
