a finch's beak and a human's body
Yuval Noah Harari spoke at an occasion saying, “Humanity has not changed really since the Stone Age. We are still the same people that we were in the Roman Empire, in Biblical times, or in the Stone Age; we still have the same bodies, the same brains, and the same minds as the people who painted the cave art” For a scholar, what an admission. In the course of progress through evolution, since the stone Age is a long time, with no changes, but for the ones that would be considered defects or anomalies. No evolutionary change; that is incredible. Meanwhile, the evolutionary progression of the finch’s beak carries on in a bit of a hasty manner. I will explain, “In the Department of Genetics at Harvard Medical School, 26 bird embryos were examined, using gene chips that reveal which genes are most active in the heads of the developing finches. This activity was then matched with the size and shapes of adult beaks” I will get to the meat of the issue here, but make one aside. Note that a chip is being used to research the bird embryos. Back to the beak: “Using modern genetic analyses, they found a molecule that regulates genes involved in shaping the beaks of Darwin finches. ‘Calmodulin’” is a protein that eventuates the signaling to turn beak designing and growth on and off. Mind you, finches have existed for two to three million years. If it has taken so long for a bird to evolve all the many subspecies and types with many different beaks, how long would it human bodies to change? Saying that the human has been the same structure since the Stone Age, from two to three million years ago, and that would not evidence a change in human form? Interesting how evolution changes our perception of the world. It seems that when something is considered from the evolutionary point of view, it has more credence to the scholars and their minions. Harari makes multiple claims throughout his work as a scholar about many topics. It would be good for a reader to not take everything Harari writes and says hook, line, and sinker. I realize I take on an interdisciplinary stance here, but I have been around some time and investigated many fields. Returning to the chip mentioned earlier, it must be understood that if a chip can do that, what could a chip do if inserted into the human body?
