Radiometric dating origin of life
Evolution encompasses a wide range of phenomena: from the emergence of major lineages, to mass extinctions, to the evolution of antibiotic resistant bacteria in hospitals today.
However, within the field of evolutionary biology, the origin of life is of special interest because it addresses the fundamental question of where we (and all living things) came from.
Many lines of evidence help illuminate the origin of life: ancient fossils, radiometric dating, the phylogenetics and chemistry of modern organisms, and even experiments.
However, since new evidence is constantly being discovered, hypotheses about how life originated may change or be modified.
Bishop James Ussher, a 17th-century Irish cleric, for example, calculated that creation occurred in 4004 B. There were many other such estimates, but they invariably resulted in an Earth only a few thousand years old.
By the late 18th century, some naturalists had begun to look closely at the ancient rocks of the Earth.
Therefore, chemical and nuclear reactions would not change.
However, the speed of chemical and nuclear reactions would change, because the vibrational frequencies of atoms and nuclei would change.
The assumptions that need to be made in order to take these results and use them as a dating method are unproven and unprovable. 57“This is the one that assumes that neither the parent nor the daughter concentrations (nor any of the intermediate products, some of which are highly-mobile gasses) have been altered throughout the entire history of the rock (except by radioactive decay) or that the amount of loss or gain can be known. Morris, “The Young Earth”, 2000, p.53John Morris calls this assumption “the Achillies heel of radioisotopic dating” (“The Young Earth”, p. Obviously no one can assume to know what the original composition of a rock sample was millions of years ago.Radiocarbon dating is one such type of radiometric dating.A process for determining the age of an object by measuring the amount of a given radioactive material it contains.It's important to keep in mind that changes to these hypotheses are a normal part of the process of science and that they do not represent a change in the basis of evolutionary theory.Here, you can learn about important hypotheses regarding when, where and how life originated and find out how scientists study an event that occurred so long ago.
