He described this as "a cranky, crazy, crab-apple tree of language and with the sharpest, juiciest flavour that I've heard for a long time".
Many deride attempts to reconstruct the family tree of languages beyond the most obvious groupings like the Romance languages and Indo-European.
It is possible to derive a phylogenetic tree of languages based on the similarities and differences in vocabulary.
If (f_{i}) is the set of branches describing the full language family profile of language i, the transition probability (t_{ij}) corresponds to the count of shared branches in the family tree of languages i and j, and is computed as t_{ij} = |f_{i} cup f_{j}|.
Otherwise, he would have had to comment on the most interesting fact that, at the very same date than Darwin published his famous tree, outside the field of biology, in linguistics and philology, a most famous tree of languages was also published by August Schleicher.
There is something awry in the idea that Tolkien's wondrous inventions — an entire history and landscape, plus trees of unknown languages, grown from one man's fancy — should be transmitted through a medium newly and utterly bent on realism.
If that family tree of human language could be reconstructed and its branching points dated, a wonderful new window would be opened onto the human past.
The researchers collected hundreds of words from different language families for example, the word for two from 95 different Bantu languages determined which were homologous to one another, and used this information to construct a family tree of the language group.
But starting about 10 years ago, computer methods originally designed to infer trees from molecular sequence data made their way into the analysis of large linguistic datasets, leading to a resurgence of language trees 9– 15.
In this paper, we presented posterior probability distributions of language trees calculated under three different models of language evolution.
