Schleicher (1821-1868) “These assumptions, which follow logically from the results of our re- search, can be best illustrated by the image of a branching tree.” (Schle- icher 1853: 787) 10 / 45
Schmidt (1843-1901) “You can turn it as you want, but as long as you stick to the idea that the his- torically attested languages have been developing by multiple furcations of an ancestral language, that is, as long as you assume that there is a Stammbaum [family tree] of the Indo-European lan- guages, you will never be able to explain all facts which have been assembled in a scientifically satisfying way.” (Schmidt 1872: 17, my translation) 12 / 45
Schmidt (1843-1901) “I want to replace [the tree] by the im- age of a wave that spreads out from the center in concentric circles be- coming weaker and weaker the far- ther they get away from the center.” (Schmidt 1872: 27, my translation) 13 / 45

Past The Geological Evidences of The Antiquity of Man with Remarks on Theories of The Origin of Species by Variation By Sir Charles Lyell London John Murray, Albemarle Street 1863 21 / 45
Past If we new not- hing of the existence of Latin, - if all historical documents previous to the fin- teenth century had been lost, - if tra- dition even was si- lent as to the former existance of a Ro- man empire, a me- re comparison of the Italian, Spanish, Portuguese, French, Wallachian, and Rhaetian dialects would enable us to say that at some time there must ha- ve been a language, from which these six modern dialects derive their origin in common. 21 / 45

Past: Uniformitarianism (Charles Lyell) Uniformity of Change: Laws of change are uniform. They have applied in the past as they apply now and will apply in the future, no matter at which place. Graduality of Change: Change proceeds gradually, not abrupt. Abductive Reasoning: We can infer past events and processes by investigating patterns observed in the present, which becomes the “key to the interpretation of some mystery in the archives of remote ages” (Lyell 1830: 165) 22 / 45
Past: Uniformitarianism (August Schleicher) Language Change is a gradual process (Schleicher 1848: 25). is a law-like process (Schleicher 1848: 25). is a natural process which occurs in all languages (Schleicher 1848: 25). universal process which occurs in all times (Schleicher 1863[1873]: 10f). allows us to infer past processes and extinct languages by investigating the languages of the present (see Schleicher 1848: 25). 23 / 45

• language-specific • limited • widely varying • constant • mutable In order to identify homologous words in different languages, corresponding segments and mappings between the alpha- bets have to be identified. Phonetic alignment is thus similar to the task of aligning two sequences which have been drawn from two different alphabets! 31 / 45

Gain-loss pro- cesses are far too simple to model the complex relations be- tween cognate words. 33 / 45

and Prokaryotic Evolution Eukaryotic and Prokaryotic Evolution Eukaryotic populations generate tree-like divergence structures over time, while genome evolution in prokaryotes generates both tree-like and net-like components. Evolution and Language History Recalling the scores on borrowing frequency in the descendant languages of Latin, it seems obvious that language history shows a much closer resemblance to prokaryotic evolution than to eukaryotic evolution. When trying to apply methods from bioinformatics to linguistic problems, it seems therefore more fruitful to use those methods that explicitly deal with prokaryotic evolution. 35 / 45
and Prokaryotic Evolution Biological methods dealing with both vertical and horizontal processes of evolution may provide interesting and new in- sights into the dynamics underlying language history. 39 / 45
and Semantic Change Semantic change plays a crucial role in language change. Al- though most linguists assume that it proceeds according to certain general patterns, we currently lack the empirical basis to pursue the question in depth. Normally, semantic change proceeds by cumulation and reduction. 40 / 45

and Semantic Change Polysemy networks bear a strong potential to investigate both cognitive and cultural forces underlying semantic change. Evolutionary biology, with its strong background in the ap- plication of network methods, may inspire the development of innovative approaches to study cross-linguistic polysemy data. 42 / 45

and Tree Reconciliation The complex patterns of lexical change create complex re- lations between the words in linguistic datasets. So far, no formal methods are known to detect and analyze these rela- tions. Methods for tree reconciliation in biology may provide great help in reconciling the individual history of words with the general history of languages. 44 / 45
