A world of categones devmd of spirit waits for life to return. Saul
Bellow, Humboldt's Gift The stock-in-trade of communicating
hypotheses about the historical path of evolution is a graphical
representation called a phylogenetic tree. In most such graphics,
pairs of branches diverge from other branches, successively
marching across abstract time toward the present. To each branch is
tied a tag with a name, a binominal symbol that functions as does
the name given to an individual human being. On phylogenetic trees
the names symbolize species. What exactly do these names signify?
What kind of information is communicated when we claim to have
knowledge of the following types? "Tetonius mathewzi was ancestral
to Pseudotetonius ambiguus. " "The sample of fossils attributed to
Homo habzlis is too variable to contain only one species. "
"Interbreeding populations of savanna baboons all belong to Papio
anubis. " "Hylobates lar and H. pileatus interbreed in zones of
geographic overlap. " While there is nearly universal agreement
that the notion of the speczes is fundamental to our understanding
of how evolution works, there is a very wide range of opinion on
the conceptual content and meaning of such particular statements
regarding species. This is because, oddly enough, evolutionary
biolo gists are quite far from agreement on what a species is, how
it attains this status, and what role it plays in evolution over
the long term."
