Dot to dot A new skill every day In five minutes Hey guys, nice skill today No sound effects, nothing fancy But what it tells you is quite interesting They're all about common misconceptions Hello, mixer Open common misconceptions Here's your common misconception Benjamin Franklin did not propose that the wild turkey be used as the symbol for the United States instead of the bald eagle While he did serve on the commission that tried to design a seal after the Declaration of Independence His proposal was an image of Moses His objections to the eagle as a national symbol and preference for the turkey was stated in a 1784 letter to his daughter in response to the society of the Cincinnati's use of the former He never expressed that sentiment publicly Open common misconceptions Here's your common misconception Humans did not evolve from either of the living species of chimpanzees Humans and chimpanzees did, however, evolve from a common ancestor The two modern species are humans' closest living relatives Some anthropologists and primatologists describe humans as a species of chimpanzee The most recent common ancestor of humans and the other living chimpanzees lived between 5 and 8 million years ago Fines of the 4.4 million year old adipithus indicate the ancestor was a moderately competent bipedal walker rather than a knuckle walker And was small and rather more long-limbed than a chimpanzee with a shorter smout Contrary to the idea of chimpanzees as primitive, they too have evolved since the split Becoming larger, more aggressive, and more capable climbers, with longer fingers Together with the other great apes, humans and chimpanzees constitute a family hominidae This group evolved from a common ancestor with the old world monkeys some 40 million years ago Wow, that was a long one Let's do one more and hope it's not so long, but that was really interesting Alexa, open common misconceptions Here's your common misconception Alcoholic beverages do not make the entire body warmer The reason that alcoholic drinks create the sensation of warmth is that they cause blood vessels to dilate and stimulate nerve endings near the surface of the skin with an influx of warm blood This can actually result in making the core body temperature lower As it allows for easier heat exchange with a cold external environment It's true, if your skin's hotter it's going to regulate, uh, radiate more heat away Cool, there you go, common misconceptions, really good This is Robin signing off, speaking again tomorrow Feedback, comments, demos The.podcast at gmail.com Recast.fm The.podcast at gmail.com
