Fahrenholz's rule is supported when: comparison of phylogenies for host and parasite show a correlated pattern of evolution
<h3>What is Fahrenholz's rule ?</h3>
The close correspondence is observed between the taxonomy of parasites and their hosts and this has led to Fahrenholz's rule. This rule postulates that parasites and the hosts speciate in synchrony.
This leads to a prediction that phylogenetic trees of parasites and their hosts are topologically identical.
when the only events in the process of reciprocal natural selection in the host and parasite lineages were those of contemporaneous speciation in both the lineages then host and parasite phylogenies are fully congruent, hence supporting Fahrenholz'srule.

“Two species of crickets, Gryllus rubens and
Gryllus texensis, have different courtship songs which can be identified only
by the opposite sex of their own species” is an example of behavioral isolation.
Behavioral
isolation is an
important evolutionary mechanism that helps members of the same species
identify each other as proper mates.
