However, it is also used to determine ages of rocks, plants, trees, etc. When the sun’s rays reach them, a few of these particles turn into carbon 14 (a radioactive carbon).The highest rate of carbon-14 production takes place at altitudes of 9 to 15 km (30,000 to 50,000 ft).It also mentions another skeptic, Dale Drinnon, who is reported to have had a problem with confirmation bias.Yet a portion of this blog post gives details on “the old photograph that is now called ‘Ptp’.” It mentions that the photo is supported by two scientists. This includes the exciting discovery of a prop under the beak of the beak of the apparent Pterosaur Hoax or Genuine?In January of 2017, the physicist Clifford Paiva and I talked by phone and agreed that the photograph now called “Ptp” has an authentic image of a modern pterosaur.
He is presently employed in the Space & Atmospheric Sciences Group at the Los Alamos National Laboratory.acquired trait: A phenotypic characteristic, acquired during growth and development, that is not genetically based and therefore cannot be passed on to the next generation (for example, the large muscles of a weightlifter).adaptation: Any heritable characteristic of an organism that improves its ability to survive and reproduce in its environment.Additional discoveries confirmed our initial conviction: Not only is the photo quite old, probably recorded before about 1870, but the animal shown is a real pterosaur.The following is a partial list of resources, recent online publications on this wonderful discovery of a modern pterosaur (pages and posts published in 2017, mostly from February through mid-May).
Then, even if circumstances change such that it no longer provides any survival or reproductive advantage, the behavior will still tend to be exhibited -- unless it becomes positively disadvantageous in the new environment.
