  Around 10,000 BCE, the transition to the Neolithic era occurred, marking a significant shift in human cultural development. This era is known as the New Stone Age and saw the development of agriculture and domestication of animals. Neolithic is a revolution here complete shift from the use of microliths (small stone tools) to large scale tools . Around 10,000 BCE, the transition to the Neolithic era occurred, marking a significant shift in human cultural development. T his era is known as the New Stone Age and saw the development of agriculture and domestication of animals. With the advent of settled farming communities, humans began to form more complex societies, and cultural development accelerated. The Neolithic Revolution led to the establishment of permanent settlements, the development of pottery, weaving, and more advanced tools .There is no social inequalities Morgon termed as "primitive communalism " . As time passed, human cultures continued to evolve and dive

 Water is everywhere , is it still  relevant today? It is a question of everyone on this earth.usually  a human foetus is 95% water; the water content of an adult liver is 73%; that of the nervous system’s tissues is 84%. Our planet is seven-tenths water,but how one can realted with efficiency of water on this palnet ?   so it is question which must be asked br self how we utilise it .Recently in rural india also, see the scarcity of drinking water along with urban areas.. i usually see  efficiency  graph of water consumption ....then i see that people misuse water due to various factor like lack of awarness,electricity subsidy,administration failure ,as well as  government poor intrest in it. i share a story  recently launched a scheme on water, where my street filled with water due to government scheme ,yes you are reading correct, but how it is possible? yes it is possible due to mointoring issue ,goverment staff  rarely visit on the site in addition to , also due to lack of resposi

1. Human evolutionary trend is characterized by a number of morphological, developmental,physiological and behavioural features.  2. The most significant of these trends are Bipedalism, encephalization, refinements of has structure, reduction in face, jaw and tooth size, decreased sexual dimorphism, refinement of tool design, power and precision grip.  3. Due to the achievement of Bipedalism, several changes have taken place in the skeletal structure. 4.Increased brain size and the complexity were probably related to tool manufacture and use,increasing environmental challenges, and more complex social groups, among other factors.  5. Change in food habits resulted into the reduction of prognathus face, decrease in the size of teeth.  6. Gradual development of brain, freeness of hands, and development of precision grip helped humans to gradually prepare refine and effective tools.  7. The complete replacement model of human dispersal denotes that anatomically modern populations arose in

There are several theoretical scenarios proposed by scientists for how the world or humanity might eventually meet its end. Some of these scenarios include:  (1.) Asteroid Impact: A large asteroid colliding with Earth could cause catastrophic destruction, leading to mass extinctions and potentially threatening human civilization. (2.) Supernova Explosion: If a nearby star were to undergo a supernova explosion, the intense radiation and energy could have devastating effects on Earth. (3.) Global Pandemic:A highly contagious and deadly global pandemic could spread rapidly, leading to widespread illness and mortality. (4.) Nuclear War: A large-scale nuclear conflict between nations could cause global devastation, with severe environmental and humanitarian consequences. (5.) Runaway Climate Change: Continued greenhouse gas emissions and climate change could lead to severe environmental disruptions, affecting ecosystems and human societies. (6.) Heat Death of the Universe: In the

The formation of the universe is explained by the Big Bang theory, which is the prevailing scientific model for the origin and evolution of the cosmos. According to this theory, the universe began as an extremely hot and dense point, often referred to as a singularity, about 13.8 billion years ago.  Here's a simplified overview of the process  (1) Singularity :At the very beginning, all the matter, energy, space, and time in the universe were concentrated in an infinitesimally small and incredibly dense point called a singularity.  (2) The Big Bang : Around 13.8 billion years ago, the singularity underwent an intense explosion, known as the Big Bang. This event marked the birth of the universe. It is important to note that the Big Bang was not an explosion like one we think of in everyday life. Instead, it was a rapid expansion of space itself, leading to the formation of matter and energy..   (3) Cosmic Expansion : In the immediate aftermath of the Big Bang, the universe underwent
