(1)Prevailing linguistic theories,based on the rapid evolution of words, suggest a limited scope fortracing languages back in time.
(2)Dr. Quentin D. Atkinson employing sophisticated statistical methods akin to thoseused in constructing genetic trees from DNA sequences, concentrateson phonemes,indicates a striking pattern
(3)This phonemic pattern mirrors the established concept of decreasinggenetic diversity with distance from Africa, hinting at southwesternAfrica as the origin of modern human language.
(4)Each migratory offshoot results in diminished geneticdiversity, a phenomenon paralleled in phonemic diversity as noted byAtkinson. |
