anthropologist Geoffrey Clark echoed this view in 1997 when he wrote that 'we select among alternative sets of research conclusions in accordance with our biases and preconceptions -- a process that is, at once, both political and subjective.'In the case of fossils; which are essentially bones that have fossilized, meaning turned to stone; fossils are generally dated on the basis of factors other than radiometric dating; such as a particular date may be chosen for a fossil because Thus, if "Fossil A" is believed to be 4,000,000 years old, "Fossil B" may be dated to be 3,700,000 years old solely on the basis of the date of "Fossil A" and a belief in evolution (i.e.

it is dated based on where "Fossil B" fits on the phylogenetic tree relative to "Fossil A"). when an unstable parent atom becomes a stable daughter atom, the dating of the specimen can no longer be done accurately), dating of old fossils is generally impossible to do directly.

Using potassium-argon dating as an example, potassium-40 decays into argon-40 with a half-life of 1.25 billion years.

While the material is molten, the argon gas will escape. Thus the rock starts off with 100% K-40 and 0% Ar-40.

By giving his bones a date of 9,000 years old, they are claiming to prove that Adam and Eve were not placed on this earth about 6,000 years ago, which would be the date a Bible scholar would pick for the creation of Adam and Eve.

When you have a wide variety of animals at a specific water hole, there is likely to be fighting, either because these species always fight when they are in the same location or they may fight to get water, such as during a drought.

The most widely used tool to measure the age of the Earth is radioactive decay.

The great scientist Ernest Rutherford was the first to define the concept of “half-life,” that is, the time it takes for one half of the atoms in a given quantity of a radioactive element (such as plutonium) to decay into another element (such as uranium), or for one isotope of an element (such as carbon-14) to decay into another isotope of that same element (such as carbon-12)...

There are a variety of ways of doing this; here is a common method.reported that, “when researchers suggested in August [2008] that the sun causes variations in the decay rates of isotopes of silicon, chlorine, radium and manganese, the physics community reacted with curiosity, but mostly with skepticism” (Ibid.).Despite this skepticism, there is proof that this is true.For example, a team at Purdue University in Indiana was monitoring a lump of manganese-54 in a radiation detector box to measure the isotope’s half-life.At PM on December 12, 2006, the instruments recorded a sudden dip in radioactivity.
