Sounds Studied as Origins of Human Language
BIRMINGHAM, ENGLAND According to a
Live Sciencereport, basic human vocalizations may have been vital in the development of the first human languages. Linguist Marcus Perlman of the University of Birmingham and his colleagues asked more than 800 participants, who spoke 25 different languages, to listen to sounds produced by English speakers and assign one of six words to each. The intended meaning of the sound was included in the six available words, which were grouped into six categories based upon people, animals, objects, quantifiers, and demonstratives thought to have been important to the survival of early humans. The words included child, man, woman, tiger, snake, deer, knife, fire, rock, water, meat, fruit, gather, cook, hide, eat, sleep, dull, sharp, big, small, good, bad, and this or that. Overall, the researchers found that people could accurately identify the intended meaning of the vocalizations more than 60 percent of

TEL AVIV, ISRAEL Early humans were apex predators who ate mostly meat for a period of two million years, according to a statement released by Tel Aviv University. Miki Ben-Dor and Ran Barkai of Tel Aviv University and researcher Raphael Sirtoli reconstructed the Paleolithic diet through an examination of current metabolism, genetics, and physical build, and a variety of scientific disciplines, suggesting that even though human behavior changes rapidly, our bodies evolve slowly. Ben-Dor explained that modern humans have highly acidic stomachs compared to omnivores, which would have provided some protection from harmful bacteria found in old meat. The researchers also claim that modern humans have a larger number of smaller fat cells, similar to other predators. Omnivores, in contrast, have a small number of large fat cells. The modern human genome, they add, allows for the digestion of a diet rich in fats, rather than a diet rich in sugars. Archaeological eviden
