Scientific controversy concerning radioisotopic dating


They argue for the Abrahamic accounts of creation, and, in order to attempt to gain a place alongside evolutionary biology in the science classroom, have developed a rhetorical framework of "creation science". Dover, the purported basis of scientific creationism was exposed as a wholly religious construct without formal scientific merit.The Catholic Church now recognizes the existence of evolution (see Catholic Church and evolution).Scientists and theologians have written eloquently about their awe and wonder at the history of the universe and of life on this planet, explaining that they see no conflict between their faith in God and the evidence for evolution.

So what else do the observations say about these REE dating methods?

Since both the daughter and index isotopes vary in time, establishing an initial daughter concentration (via the isochron method) becomes problematic because the y-intercept of the linear plot cannot be assumed to be the primordial ratio of Geochronologists solve this problem by using “stony meteorites” to establish a primordial isotope ratio for This method assumes that the terrestrial Nd has evolved in a uniform reservoir whose Sm/Nd ratio is equal to that of a chrondritic meteorite that is further thought to be similar in composition to the current photosphere of the sun minus the volatile elements.

Hence, the logic used to estimate the initial value of the daughter isotope concentration springs from the evolutionary models for solar system formation and is, again, quite circular in its essence.

Within the Christian world, creationism was once widely believed to be true, but since the mid-19th century evolution by natural selection has been established as an empirical scientific fact.

Christian fundamentalists dispute the evidence of common descent of humans and other animals as demonstrated in modern paleontology, genetics, histology and cladistics and those other sub-disciplines which are based upon the conclusions of modern evolutionary biology, geology, cosmology, and other related fields.

The inhomogeneous distribution of Lu and Hf in granitic rocks and their sensitivity to alteration during metamorphism create reproducibility problems for the Lu-Hf model.
