Evolution: Myth or Reality

 People love to express their knowledge. From early days of human civilization, people are transferring their knowledge to other people which may be a new generation or fellow human living in different tribes or geographical locations. One topic that have been at the center of human curiosity and exploration of natural phenomenon is that how life was created on #earth. As the hypotheses and theories, trying to give an answer for the origin of life on earth, increased in numbers a special focus was given to evolution of various forms of life on earth. We see life in different forms. For example we can see life in plants, fish and other aquatic creatures and animals walking on earth. All animals are alike. We see animals of different sizes and body types. From ancient times, there has been two theories circulating in societies and still discussion in going on. First theory states that all living creatures were created in their present form.

Other theory states that current form of life has evolved from earlier simpler forms of life. This theory states that early form of life on earth was very simple. Early living organisms were simple unicellular organisms. Gradually these cells came together by evolutionary process and form multicellular simple organisms. This simple step took millions of years to be completed as evolution is very slow process. Due to its extremely slow pace people find it hard to believe in evolution as life span of human is not that long to observe considerable change in life forms. However in recent times, scientist were able to gather many facts to support their theories of evolution. DNA analysis has shown that all animals living on earth are have some DNA material common each other. For example birds, mammals and fish all have somewhat common DNA sequences indicating a strong relationship among ancestors of al these. However due to high complexity and invisibility of DNA this appears to be a counter intuitive for most people and desire to observe evolution with own eyes does not end. Thanks to hard work of biologists we have found live evolution evidence in living organisms. Peppered moth evolution is one example. During industrial revolution, peppered moth changed their skin color and dark skinned moths became normal. Presence of redundant organs in humans and other organisms also provides hints of evolution. Another very big evidence of evolution has been observed in modern human (#homosapiens) is disappearance of wisdom teeth in newly born babies. Yes yes you read it right. Do not get surprised. Wisdom tooth is disappearing fast in humans. New born babies do not have a place for growing wisdom tooth and it is expected that it will fully disappear in few years.
This disappearance is caused by no real use of teeth during life time of a human. Where this new discovery gives a strong evidence about evolution it also poses a question about evolutionary process. If a redundant organ gets disappeared why still we have appendix. Appendix is considered to be a redundant organ. It seems like despite the facts supporting evolution, this discussion of evolution does not appear to be ending in general public. As far as we are considered we supporters of evolution theory. Are u a supporter or you have another idea about this. Do share your opinion with us in comment section.

Science: Saviour of mankind

 Earth has been house to life for millions of years. When we speak of life on earth, most exotic topic that comes to our minds is of Dinosaur reptiles. Many movies have been produced featuring different species of dinosaurs. It seems like this was the first form of life that appeared on earth but this is not true. Earth was house of life even before appearance of dinosaurs. After passing through millions of evolutionary years and processes earth witnessed the birth of mankind. With the arrival of human, a new era started on earth. At the start of human race, environmental conditions were very harsh. To cope up with these harsh conditions, human made use of greatest tool ever used or developed by all species on earth. Name of that tool is science. At the beginning there was little knowledge of different things happening around the humans. As the time passed more and more knowledge regarding the environment was accumulated that lead to series of inventions and discoveries. These inventions made things easier for humans. One such example is related to fire. When there was no concept of fire, humans faced many problems to keep themselves warm in cold weather. Once the process of igniting and maintaining fire was established, keeping warm inside a cave became much more easy. After discovering insulating capacity of different material, and use of these materials to cover bodies lead to even more comfortable winters. There is very long list of these discoveries that lead to modern day life style of humans on earth. We will discuss some of these discoveries in some other post. After so many discoveries and years of presence on earth human are still facing challenges to live on earth. One of the biggest challenges in modern area is food security. With continuous increase in population and reduction in agricultural land has created food crisis. In this grave challenge, again, science is helping us to overcome this problem. Though problem of food security has not been solved completely but there is tremendous increase in food production from same old agricultural land. New animal farming techniques are being developed in order to maximize meat and milk production in least possible time. Most recent attempt in this regard is lab grown meat. Though it seems very strange concept but scientists are working vigorously on this idea. If , one day, we are able to grow meat in lab, will you be the one who oppose such developments or will you promote such projects for protein shortage to come to an end. As for agricultural products are concerned multi layer farming is being introduced to increase production many folds. As these new methods give us hope to over come food crisis in future, there is still time to witness effectiveness of these methods. Only time will tell if science will again be saviour of man kind in this new challenge.
