Although Homo sapiens started thinking from more than 150,000 years ago, the recorded history of the species is too low – only for the past 10,000 years. Even so, the intellectual growth of humankind as a species is confined to an even smaller period, the past 4000 years only! It was during the past 4 …
The evolution of Homo sapiens was not an easy process, but rather a long sequence of divisions within the species, with one of the divisions dying out and the other evolving into a different family group, but the common factor between the human evolution and any other organism’s evolution process was that the process involved …
Fossils In the fifth extinction event we saw the death of dinosaurs around 65 million years ago; quite recently we might say, considering the long history of the existence of life on Earth. Our usual view of history involves a picture of different types of dinosaurs roaming about the surface of Earth and the famed …
Water on Earth! The implication of the afore developments was that the planet, which started out as a ball of gases and elemental rocks, had stabilised to form a round, rocky body surrounded by gases and steam. With the emergence of steam that accumulated above Earth’s surface gradually, water was set to be available in …

Iron, being a dense nucleus, will not allow any addition of new neutrons or protons inside it. So the element production process came to a pause. With the stars’ mass increasing every minute by the formation of newer, heavier elements, after a critical point, the stars started to collapse in on themselves. The density of …
The process of life which started out as RNA and DNA had branched out in the earlier periods of Earth’s history with the evolution of eukaryotic cells. Eukaryotes then evolved further into multicellular organisms of various shapes and sizes. The evolution of multicellular life forms first began around 500 million years ago, a relatively short …
Matter, Antimatter and the Subatomic Universe In the expanding, newly formed universe, the particles were in constant motion at very high speeds. The heat expelled out of the Big Bang kept pushing them randomly. It never let them to slow down. What accompanied the particles in their early years of formation were their corresponding antiparticles, …

The Big Bang is the theory (nah, not the TV series) which explains the origin of the universe and was propounded in the mid-twentieth century after the wide acceptance of Albert Einstein’s Theory of Relativity. Our understanding of the laws of physics, like gravitation, Newton’s laws of motion, etc. pointed us in a direction that …
The self-replicating amino acids formed long chains of themselves, and they were aided by another set of molecules called the phosphates. The phosphates gave rigidity to the amino acids by forming a strand alongside them, where the amino acids latched on to. Such structures of amino acids on phosphate strands were named to be the …
What life forms are we and how did we evolve into us? Our knowledge of biology points in the direction of different life forms which have evolved in our planet through time. The result being us, the six-sensed monkeys. Also, coming to our minds is the different classifications of life forms (or) living organisms based …
