There have been so many attempts to understand the human behavior, yet it refuses to come into the grasp or to follow some universal formula. Wise men started to understand it with animals (we being one of them) and the father of Evolution , Charles Darwin, came up with the formula “The species always compete for the resources and those who the fittest among them survive and ready themselves for another competition”. He called it survival of the fittest. It is the nature’s way of weeding out the weaker among the species. This is the way all living beings have… Read More »Evolution of Living Beings
Microbes may be very small in size but their sheer numbers and remarkable adaptability to the existing climates is astounding. The word microbe is derived from micro-organisms meaning they are so small that they cannot be seen with naked eyes. A microscope is required to see them. But these tiny organisms are so active that they can bring about mammoth changes into the environment in which they live. Most of the chemical changes on the earth are brought about by these microorganisms. When the earth first formed, the atmosphere consisted only of carbon dioxide and water. Due to this iron… Read More »Mighty Microbes !!
I had a long cherished wish to watch the evolution in the making. But lifespan of us humans is infinitely short to witness the events taking place during the evolution which span over thousands or sometimes million years. But my desire grew with time. So I many a times felt anguished and helpless. We are living in a time when it is quite easy to access information. On the scientific front, there are wonderful instrument which are available making the life of a scientist comparatively easy. Think of the times, when Darwin, Newton, Kekule did their research. They were the… Read More »Watching the Evolution
Man’s penchant for getting drunk is much older than keeping himself clean. I mean the use of alcohol and other substances obtained from plants which give high is much older than the invention of soap for cleaning the body. But it is not only the humans who feel the need to get a high but many animals also are similar. Johann Hari, who is the author of book “Chasing the Scream: The First and Last Days of the War on Drugs” has spent 25 years observing the behaviour of animals when they are alarmed or in grief. He began his research… Read More »Animals take drugs when in grief
In the Beginning there was nothing……… Man came into this world after so many living beings. From aquatic life an odd animal slithered onto the adjacent soil. Amphibians were born. Then chance gave some to evolve and mutate into purely land dwellers. The some species looked to the skies and slowly evloved into the birds. Amongst the land dwellers there must be some physically weaker which learned to climb trees because the trees provided safety from animals on the land. At last humans ancestors evolved and then homosapiens. In the beginning it was only an animal thing and requirements: Safety… Read More »What was there in the beginning ?
It is a species of large owls found in india. They are very rare in our area in Punjab. I was lucky to spot this beautiful owl in a forest near my village. As such, it chooses its roost so cleverly that it completely camouflage itself. Only sometimes it is noticed by crows , treepies and babblers who make a hell of noise near it and force it to fly away. Only during one such cacophony I spotted it. After many unsuccessful efforts finally I was able to photograph it.
Human beings always tend to recall the past incidents in their lives to compare with the present events. Since birth, the events become memories and are lodged into the brain. In which manner do the memories lodge inside our brains ?. Are they stacked one over another like sedimentary seams ? But that may not be the case because retrieval of the deepest buried memories shall be very difficult. Are they scattered in different places in the brain. This way retrieval may be easier. Brain might be the most complex structure to delineate although like most of our other body… Read More »Memories in the Brain
Equality between members of a species is against the nature’s law of evolution because it is the survival of the fittest. Nature continuously weeds out and eliminate the unfit. Despite the saints or preachers in every faith and all over the globe trying their best to persuade the human beings to be like brothers (equal), disparity is always there. Humans have divided themselves along the lines of region, religions and caste systems. That is why human beings cannot become equal. In fact the desire for superiority over others propels the human progress because to be superior one must strive harder… Read More »Equality Between Human Beings is Contrary to Evolution
There is a river which flows near my home. Most of the time during the year, amount of water is very limited except during monsoon season when the rains in the catchment area flush it with plenty of water. For rest of the time, it is mostly a dry bed of pebbles, stones and sand. People roam in it. Many people immerse idols in it along with the flowers and other things of worship. Flowers are mostly marigolds. Their sometimes get lodged in the clayey soil on the edges of flowing water. Such plants which grow unattended are called Escapes,… Read More »Growing by themselves
Scientists have marked the time since the Earth began its life. They have divided it into different Epochs, Periods, Eras and Eons progressively in increasing time groups. We are living in the following division of time. Eon: Phanerozoic Era: Cenozoic Period: Quaternary Epoch: Holocene Holocene epoch began roughly 11700 years back and continues till present. United States Geological Survey (USGS) has divided this time into three ages namely Greenlandian: 11700 to 8326 years ago Northgrippian: 8326 to 4250 years ago MEGHALAYAN: 4250 to present date MEGHALAYAN age marks the time when a mega drought devastated civilizations across the world,… Read More »We are living in the Meghalayan Age
