Human Evolution

Human Evolution is the change in the genetic pool of a population from one generation to the successor generations by the process of mutation, natural selection and genetic drifting. For the process of evolution to occur there needs to be variation, selection, heritability and reproductive success. For the modern humans, there are more factors of evolution and selections at work. Humans have, senses, influenced our own evolution and as well as other organisms through our behaviour, lifestyles and technologies. Humans have preserved many species to extinctions that helps to keep some species alive that are “predisposed” to extinction, and our advances in modern medicine keeps individuals alive who would have died without it.
Human evolution is indeed a long time process of changing by which people originated from ancestors. Many Scientific theory and evidences proved that the physical and behaviour inheritance shared by all the people originated from apelike ancestors and evolved over a period of approximately several million years ago.
Humans are the sole hominin species in existence today. Thus, it's easier than it would have been in the ancient past to distinguish ourselves from our closest living relatives in the animal kingdom. Primatologists such as Jane Goodall and Franz de Waal, however, continue to clarify why the lines dividing human from non-human aren't as distinct as we might think. Goodall's classic observations of chimpanzee behaviours like tool use, warfare and even cannibalism demolished once-cherished views of what separates us from other primates. De Waal has done exceptional work illustrating some continuity in reciprocity and fairness, and in empathy and compassion, with other species. With evolution, it seems, we are always standing on the shoulders of others, our common ancestors.
One of the earliest human existence traits, bipedalism and the abilities to walk on two legs has evolved over more than 4 million years ago. Other important human characteristics such as a large and complex formation of full brain, the ability to make and use different tools, and the capacity for different languages have developed in recently.
Humans are the primates. Physical and genetic similarities show that the modern human species which is also termed as Homo sapiens has a very close relationship to another group of primate species which are the apes or chimpanzees, Humans and the great apes of Africa chimpanzees and gorillas which share a common ancestor that lived between 8 and 6 million to trillions years ago. Humans first evolved in Africa, maximum number of human evolution occurred on that continent only. The fossils of early humans who lived between 6 and 2 million to trillions years ago come entirely from Africa.
Most of the scientists recognize some of 15 to 20 different species of early humans. Scientists do not agree, however, about how these species are related to each other or which ones simply died out.
Palaeoanthropology is the scientific study of human evolution. Palaeoanthropology is a subfield of anthropology, the study of human culture, society, and biology. The field involves an understanding of the similarities and differences between humans and other species in their genes, body form, physiology, and behaviour.

श्री अरविंद महाविद्यालय (सांध्य) COMMERCIA का शानदार आयोजन

'COMMERCIA' और 'श्री अरविंद महाविद्यालय (सांध्य)' के स्वर्णिम इतिहास में 21 और 22 फरवरी 2020 को सुनहरे अक्षरों में लिखा जाएगा। पहली बार श्री अरविंद महाविद्यालय (सांध्य) की किसी सोसाइटी ने सांध्य इंटर कॉलेज फेस्ट का आयोजन किया और साथ ही COMMERCIA ने अपने आधार की मजबूती स्पष्ट करते हुए श्री अरविंद महाविद्यालय (सांध्य) की सबसे सक्रिय सोसायटी में अपना स्थान शीर्ष पर बनाये रखा।


While the human race is locked inside the house to fight COVID 19, a pandemic which held the entire world hostage in unprecedented and unparalleled manners, while one is even debarred to visit neighborhood milk booth and one is prohibited to cross over to another district in a same state, every piece of literary work is an expression of paranoia in one way or other. View of shillong from Shillong Peak Nation is facing most harsh form of lockdown, and consequent toll on human, psychological as well as physiological, is pushing to the limit of tolerance. At this crossroad in life, picturesque lush green meadow, hills covered with pine trees, fresh air and country roads driven me nostalgic and take me far away from new normal, every time I remembered of Shillong. ‘Scotland of India’ title it rightfully defended perched in East Khasi Hill district of Meghalaya, Shillong lies at north eastern corner on Indian Map. Shillong is the capital of Meghalaya. Entomology of the word Meghalaya stands

Pandemic from the eyes of a Villager

I am a city born and have lived in cities my entire life. I have stayed in cities like Bhubaneswar, Kolkata, Mumbai and Bangalore and always had the best facilities that could be provided to a person. So, every time there was national wide concern, I always saw it from the point of view of city life.
