This adds to evidence of swings in decay rates in response to solar activity and the distance between the Earth and the sun that Purdue researchers Ephraim Fischbach, a professor of physics, and Jere Jenkins, a nuclear engineer, have been gathering for the last four years.

The Purdue team previously reported observing a drop in the rate of decay that began a day and half before and peaked during the December 2006 solar flare and an annual fluctuation that appeared to be based on the Earth's orbit of, and changing distance from, the sun, Jenkins said.

Genetic studies have also suggested that modern humans entered America from Asia even earlier, around 23,000 years ago.

haven’t accepted that,” says Bonnie Pitblado from the University of Oklahoma.

Then the paleontologists use the geologists' dates as evidence for the age of the fossils! The relative order of the strata was first determined by the principles of stratification. Beagle, a very strong Bible believer, made it a point to have a copy of Lyell's book for the ship's library.

(The principle of superposition was recognized as early as 1669 by Steno.) Reverend Benjamin Richardson and Reverend Joseph Townsend were a couple of early geologists involved in this work. Obviously, even Lyell was not pushing evolution at the time.

A team of scientists from Purdue and Stanford universities has found that the decay of radioactive isotopes fluctuates in synch with the rotation of the sun's core.

“And we noticed there was something different about it,” says Thomas Deméré, who was part of the team.By 1830 Lyell's famous textbook, Principles of Geology, came out. Such was the age of the great creationist geologists!The principle of faunal succession in the geologic record was established by direct observation as early as 1799 by William Smith.The team has not yet examined isotopes used in medical radiation treatments or for dating of ancient artifacts."The fluctuations we're seeing are fractions of a percent and are not likely to radically alter any major anthropological findings," Fischbach said.
