DNA half-life only 521 years, so is dino DNA and insect amber DNA young?

If paleontology lives by radiometric dating, it also dies by radiometric dating. Either DNA trapped in 200 million-year-old Jurassic insect amber is young or it has some unexplained source. I argue it is young. Radiometric C-14 dates of fossils say the fossils are young. As I’ve said many times, the radiometric date of 65 million-year-old rocks is irrelevant to the radiometric date of the actual physical tissue of a fossil. I could bury a living dog in 65 million-year-old rocks, and the age of rocks will have nothing to say of the age of the dog. The best inferences for time of death of a fossil: half-life of C-14, half life of DNA, half-life of amino acids, etc., NOT the Read More ›

We Have a Backup Sense of Smell to Protect the Lungs

Our noses have specialized cells that give us a sense of the vapors around us by detecting the presence of chemicals and sending signals to the brain. New research is now explaining how our lungs also have such chemosensors. These sensors send signals not to the brain but to the nearby tissues causing a fast response, such as coughing and wheezing, when we inhale irritating or toxic vapors. Our lungs need this protection since they essentially are open to the external environment. As one evolutionist explained, “it makes sense that we evolved mechanisms to protect ourselves.” But such reasoning violates Occam’s Razor and reveals again how Aristotelianism lives on inside of evolution.  Read more

The cybernetic contradiction of Darwinism

In automatic control theory “homeostasis” is defined as the property of a system in which variables are regulated so that internal conditions remain stable and relatively constant. Homeostasis is a fundamental concept in biology because is what allows the life of organisms. In fact, it maintains the stability of the organisms in response to changes in external conditions. The concept of homeostasis is tied to the strictly correlation and interdependence of all systems in a body, i.e. its functional unity. Organisms can live and survive only because are giant cybernetic hierarchical hologramatic macro-systems. Donald Johnson defines cybernetics as: … the interdisciplinary study of control systems with feedback. (Programming of Life, Big Mac Publishers 2010) While Norbert Wiener, about homeostasis, writes: Read More ›
