the answer is rRNA 
Reason: some molecules are conserved since many years and are still carried from one generation to another, they haven’t undergone any big/vast changes like rRNA and some protein sequences.
 hence, we say that rRNA ia a very imp. factor to establish HOMOLOGY, to establish relationship between various organisms
such molecules are considered as ANCESTRAL characters, and are also very useful to study CHEMOTAXONOMY.
