The nearest common ancestor of GO terms

I want to find the nearest ancestor of several GO terms from DAG. Is there any proper tools? preferably use perl or python. Thank you very much!

common ancestor go python perl

I usually search for it in a plot, but there should be a tool. The GoSims package of Bioconductor seems able to do it see page 5.

Thank you very much! I have solved my problems using GOSim, it's really a very usfull tool.

When you said ancestor I though last common ancestor. This tool is no published yet but shows you along the evolutionary lineages since when a term exists, in other words, when it has been originated, fell free to testing:
