The evolution of life is analogous to the evolution of language. For example, there are several languages based on the Roman alphabet of only 26 letters. Yet by arranging these in different orders, we’ve added several hundred thousand words to English since the 5th century, and many of them were completely new. The principle is the same in genetics. There are millions of named and classified species of life, all of them based on a variable arrangement of only four chemical components. For another example, we know that Spanish, Italian, French, and Portuguese all evolved from Latin, a vernacular which is now extinct. Each of these newer tongues emerged via a slow accumulation of their own unique slang lingo –thus diverging into new dialects, and eventually distinct forms of gibberish such that the new Romans could no longer communicate with either Parisians or Spaniards. Similarly, if we took an original Latin speaking population and divided them sequestered in complete isolation over several centuries, they might still be able to understand each other, or their jargon may have become unintelligible to foreigners. But they won’t start speaking Italian or Romanian because identical vocabularies aren’t going to occur twice. (en) |
