Linguistic Evolution Methodical comparisons among European languages, and between these and Indian languages, resulted by the early s in the creation of a formal model of the process. The most frequently cited study is by Jacob Grimm — of Brothers Grimm fame — who in formulated "Grimm's Law" describing sound changes regularly occurring over time as the Germanic languages emerged from an earlier common ancestor.

Linguistic Evolution Methodical comparisons among European languages, and between these and Indian languages, resulted by the early s in the creation of a formal model of the process.

Among other things, the concept of linguistic evolution over time builds on the fact that every language is spoken in a Essay on social evolution of dialects peculiar to separate speech communities, and that these dialects tend to drift apart if they are not in constant contact with each other.

Thus the consonant written with the letter C by the Romans was pronounced like our K in Rome. French and Italian words from the same Latin parent term, even if they are spelled identically, are therefore pronounced differently.

This allowed them to "reconstruct" purely hypothetical parent languages for which there was no known written documentation.

The expression "comparative method" was coined to refer to the inference of historical relationships among languages based on comparison of their living representatives. The model of linguistic evolution assumed an artificially unitary and hypothetical "parent" language from which various "daughter" languages had historically derived through the operation of consistent changes in the pronunciation of words or in other features in different, more or less isolated, speech communities.

When two speech forms are mutually comprehensible, they are considered to be different dialects of the same language; when they are different enough not to be mutually comprehensible, they are considered to be different languages. There are, of course, complications, but comprehensibility remains the usual way to think about the difference.

II. Biological Evolution

Any language at any time, being made up of multiple speech communities, is subject to having its dialects become separate enough to be languages in their own right. For example, even though Romanian, Spanish, and Catalan all derive from Latin, Spanish and Catalan have a nearer common ancestor not shared with Romanian.

The model accommodated this phenomenon by the idea of "branching," on the analogy of a tree or a genealogy: In the model, these tend to be artificially represented as lacking internal variation, but of course it is internal variation that produces daughter languages, so it is oversimplifying to think of them as unitary.

It was thought that underlying most European and northern Indian languages was an ultimate prehistoric tongue, Proto-Indo-European. Proto-Indo-European left no texts, but the model predicts that it has to have existed because that is the most efficient way to explain the relations among related languages today.

The study of historical relations among languages is today referred to as "historical linguistics. The Model In the world of XIXth-century scientific thought, the brilliant success of historical linguistics was only one area where "evolution" was in the air, much encouraged by discoveries in geology showing that the earth was much older than had once been thought.

One such field was biology, where the rapidly progressing discovery of new life forms including fossils and casts of extinct life forms was challenging efforts to understand their interrelationships.

It had long been clear that there were closer and more distant relations among animals: On the analogy of languages, one can imagine a great branching chart by which all modern animals are ultimately related to each other, with hypothetical ancestors and hypothetical branching linking the modern living forms.

Like the written forms of languages no longer spoken, extinct plants and animals can sometimes be fossilized, allowing for periodic confirmation of predictions. Many scholars were involved with the exciting project of trying to develop a better understanding of the relations among living things.

The name most often associated with the application of the model of ancestral forms and branchings is of course Charles Darwin, although Darwin did not satisfactorily explain everything involved or all of the implications.

For one thing, he lacked a modern understanding of genetics. For another, he had very little fossil evidence showing what extinct life forms looked like.

Biological evolution as it is understood today involves populations of plants or animals with slight genetic variation from one individual to the next.

Genetic variation in the population can increase through occasional, non-lethal genetic mutations.Darwin’s Theory of Natural Selection and Social Darwinism Essay Words | 4 Pages.
