This assumption is wrong. The amount of C in the atmosphere is still increasing. This research indicates a young earth probably less than 10, years. The same research also modifies all dates obtained by C decay. Plants and animals that lived on the earth four thousand years ago would have had much less C in their body to start with.

Over time, carbon decays in predictable ways. And with the help of radiocarbon dating, researchers can use that decay as a kind of clock that allows them to peer into the past and determine absolute dates for everything from wood to food, pollen, poop, and even dead animals and humans. While plants are alive, they take in carbon through photosynthesis. Humans and other animals ingest the carbon through plant-based foods or by eating other animals that eat plants. Carbon is made up of three isotopes. The most abundant, carbon, remains stable in the atmosphere.
Melting Ice Reveals Mummified Penguins in Antarctica
In January , Steven Emslie was finishing a season of studying penguin colonies living near Zucchelli Station, an Italian base in Antarctica. With the austral summer quickly coming to a close and all planned work completed, Dr. Emslie, an ornithologist at the University of North Carolina, Wilmington, did what any good scientist would do with a few extra days in the Antarctic: He went exploring. He had heard rumors of penguin guano on a rocky cape along the Scott Coast but knew of no active colonies there.
Laura Suffield. Hailed two years ago as one of the most important archaeological discoveries in Europe, the painted caves at Alave in northern Spain are decorated with images of animals, symbols and splashes of colour. The results of further tests released this summer have proved them to be skilful fakes. The Spanish student who discovered them is now thought to have painted the cave with natural pigments but using modern rubber sponges, fragments of which were found on the walls.
