HUMAN EVOLUTION: _ Figure below shows conservator Effie Verveniotou and human origins researcher Dr Louise Humphrey examine the oldest nearly complete modern human skeleton ever found in Britain before it goes on display in the gallery. Cheddar Man is a human male fossil found in Gough’s Cave in Cheddar Gorge, Somerset, England. Excavated in 1903, Cheddar Man is Britain’s oldest complete human skeleton. Cheddar Man lived around 10,000 years ago. Analysis of his nuclear DNA indicates that he was a typical member of the western European population at the time, with lactose intolerance, dark skin, blue eyes, and dark curly or wavy hair. ________ Prologue: Recently, minister of state for human resource development of India said that the Darwinian theory of evolution was scientifically wrong and should not be taught in Indian institutions. Many scientists and students signed a petition calling upon him to withdraw his remarks. Three science academies […]
Are ordinary people bad? ________ _______ Let me start by giving 3 examples from India: _ _ Example-1 On August 10, 2016 Matibool is on his way home from an overnight shift as a watchman, carrying a cellphone in his hand as seen in the figure above. It is dawn in Delhi. Suddenly, a speeding three-wheeled tempo barrels down on him from behind, knocking him into the air. The driver gets out, sees Matibool’s crumpled body and decides against even approaching him. In a matter of seconds, the driver is back in the truck, and away he goes. As Matibool lay bleeding for an hour, men and women riding in 140 cars and 82 rickshaws would avoid his dying body. So would 181 bikers and 45 pedestrians. At one point, an emergency response van used by the Delhi police drives by. A cycle rickshaw passes his body and stops a […]
SMARTPHONE: _______ The figure above shows transition of telephone from landline phone to smartphone. _______ Prologue: Alexander Graham Bell’s invention has come a long way since its prototype in 1876. The latest model of telephone requires no external wiring, fits in your pocket, takes dictation, and answers any question in seconds. For most of us, our compulsion to look at that little screen is so powerful that we can’t go for any more than a few minutes without checking it. Smartphones have gained so much significance in our lives that choosing one is a little like choosing a religion. Our preference for either an iPhone or an Android model seems to suggest something fundamental about who we are. Smartphone is a combination phone having computer, web browser, camera, GPS etc and therefore, if you lose your smartphone, you lose everything. There are three screens of the ‘Digital Lifestyle’ in the […]
_ SCIENCE OF LANGUAGE: _ The figure above shows English to Gujarati mappings for consonants: _________ Prologue: Human life in its present form would be impossible and inconceivable without the use of language. To the question: “Who is speaking?” Mallarme, the French poet, answered, “Language is speaking.” The traditional conception of language is that it is, in Aristotle’s phrase, sound with meaning. Everybody uses language, but nobody knows quite how to define it. Language is arguably the defining characteristic of the human species, yet the biological basis of our ability to speak, listen and comprehend remains largely mysterious; about its evolution, we know even less. The origin of language is a widely-discussed topic. Whole doctorates have been based on it, thousands of books have been written on it, and scholars continue to argue about how and why it first emerged. Many animals can communicate effectively with one another but humans […]
HAIR: _________ _ “The hair is the richest ornament of women.” Martin Luther (1483 – 1546) German religious reformer. ________ Prologue: There is universal human interest in hair and hair-styling throughout history and around the world. Hair has served as a signifier of class, gender, ethnicity, conformity/non-conformity, authority, and power throughout history. Attitudes towards hair, such as hairstyles and hair removal, vary widely across different cultures and historical periods. While some of us define ourselves by our faces and bodies, others place a lot of weight on how our hair looks. After all, hair is our body’s fashion statement. You’re born with a natural hair color, shape and hairstyle. A large part of your personal appearance is determined by your hair. Some people want to restore their hair, some want to remove it, and others just want a fancy hair style or color. Hair, whether present or absent, […]
