[Taxacom] Why character-tracking doesn't happen?

Hi, Don.

Homoplasy as used by tree-builders is an explanation for incongruence
and incompatibility. Paralellism, convegence, etc are explanations for
homoplasy. This is how the word is used.

The same thing happens with illness. Why didn't Fred and Mabel show up
to their respective jobs today? They were sick. 'Illness' is the
explanation for their absence. Flu, gastro, hangover, etc are
explanations for illness.

Best wishes,
Bob
