Humans have all been deemed guilty of procrastinating , whether you are young or old , at some point you have experienced the guilt of procrastinating. What interested me the most in the article that I read was the immediate connection I made as soon as I stumbled upon an all caps article titled : Procrastination: A Scientific Guide on How to Stop Procrastinating. The article gives us insight and scientific reasons as to why we procrastinate and how to prevent it. What attracted me to this article was the fact that I , myself as a student have been stuck in this cycle of procrastinating .What made it even worse was the immediate guilt I would feel after laying of a task that was supposed to be done. The article demonstrated several tips that gradually have you making progress towards ending the never-ending procrastination cycle. The author’s style was very intriguing , he included an abundance of rich scientific facts , which in my opinion was very enjoyable to read. Compared to other articles , this one portrays a very straightforward and easy to understand explanation of the problem and how to counter it . As a reader , I have found it to be very helpful that I found such article since many of the articles online nowadays are based on speculation and nonsense. What made me appreciate it more was the fact that the author had such a simple approach towards such complex problem. As a person who does not read too often , I have found it to be a very enjoyable read and would recommend it to anyone willing to break the never ending procrastination cycle.
Procrastination: A Scientific Guide on How to Stop Procrastinating
How did the discovery of DNA prove that Darwin’s theory of evolution was correct and how does it change the way we view evolution today and into the future?

Darwin’s theory of evolution states that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual’s ability to compete, survive, and reproduce. Understanding the DNA more has helped us verify that we indeed are descendants of a much more primitive creature like the Tiktaalik fish. The discovery of DNA has enabled us to accurately map the evolution tree that we use today, which is something that Darwin did not have at the time. It has allowed us to study Darwin’s theory in such proximity like never before. The discovery of DNA had us find out how similar we are to chimps with just a one percent difference in our DNA. Which goes out to support Darwin’s theory and his statements about how we are descendants of chimps, which at the time was widely disregarded since he had no way to prove this , because DNA was not discovered by then. He noticed how mutations could take place within the animal itself such as the Galapagos Finches. Darwin noticed how the finches have different beak types depending on the island they live on. Those different beak types each have a specific job depending on what niche the bird occupied at a certain island. For instance, one kind of finch has a short strong beak that is useful for cracking nuts , while another finch living on a different island has a long thin beak suitable for sucking the nectar out of the plants . It was the discovery of those different kinds finches that aided Darwin’s theory of natural selection, and how the fit keep getting fitter because of those mutations. Not all mutations are harmful , take the deer mice as an example. Some have mutated to have darker fur color since they live in a dark environment which easily helps them evade predators. Meanwhile other deer mice have light fur since they live on a lighter surface . Those types of mutations along with natural selection have helped the mice survive and interbreed even more. Another example of Darwin’s evolution theory that is exhibited in the Galapagos is the adaptation and change of the Galapagos tortoises. Galapagos tortoises have two very different shapes, each adapted for different feeding habits needed on low, arid islands versus high, lusher islands. For example , the Saddle back Tortoises have shells that rise in the front like saddles , This adaptation makes it easier for them to lift their heads to eat tree cactus .On the other hand , the dome shaped tortoises have their shells shaped like a dome live within an abundance of vegetation close to the ground making it less necessary for them to raise their heads to feed. The discovery of DNA has definitely helped us reach milestones we never thought could be reached and we surely will be able to reach many more with science and technology advancing .furthermore , as we advance towards the future more and more discoveries will only bring us closer to finding out the truth about the theory of evolution and how it Darwinism will stand the test of time.
