Hello,
reading this thread a question came to me:
Is there a way of automatically deriving programming languages ascendancy?

Like biologist can determine the distance between two genotypes, and determine a hierarchy between species from that.

Are you aware of researchs made in the field?

On the net I found interesting graphs but no comments on the methodology.
