Are humans primates or should there be special biological taxonomy for humanity?
Please cite evidence.

Transitional fossilhow come there are no transitional fossils in the fossil record and why dont
we see mutations on earth now?

Yes, that would be the proper terminology. Carbon-dating would not be able to detect radioactive carbon beyond 50,000 years.Goat wrote:The proper phrasing would be 'radiometric dating', not carbon dating.
Its quite telling how you decided to leave out the rest of the quote. This would be considered an example of a "quote mine"otseng wrote:
"Most man-made chemicals are made of fossil fuels, such as petroleum or coal, in which the carbon-14 should have long since decayed. However, such deposits often contain trace amounts of carbon-14 (varying significantly, but ranging from 1% the ratio found in living organisms to amounts comparable to an apparent age of 40,000 years for oils with the highest levels of carbon-14)."

This may indicate possible contamination by small amounts of bacteria, underground sources of radiation causing the 14N(n,p) 14C reaction, direct uranium decay (although reported measured ratios of 14C/U in uranium-bearing ores[15] would imply roughly 1 uranium atom for every two carbon atoms in order to cause the 14C/12C ratio, measured to be on the order of 10−15), or other unknown secondary sources of carbon-14 production. Presence of carbon-14 in the isotopic signature of a sample of carbonaceous material possibly indicates its contamination by biogenic sources or the decay of radioactive material in surrounding geologic strata. In connection with building the Borexino solar neutrino observatory, petroleum feedstock (for synthesizing the primary scintillant) was obtained with low 14C content. In the Borexino Counting Test Facility, a 14C/12C ratio of 1.94x10−18 was determined;[16] reactions responsible for varied levels of 14C in different petroleum reservoirs, and the lower 14C levels in methane, have been discussed by Bonvicini et al.[17]
Yes, that is true, and do you know WHY it is true?

However, we have deposits that are supposedly millions of years old that has the presense of C14.

If the assumptions of carbon dating are true, then the more reasonable answer is that the ages are accurate. However, since it does not conform to evolutionary timeframes, an ad hoc explanation must be provided. So, "bacteria" or "other unknown secondary sources of carbon-14 production" is posited. As for bacteria, what it implies is that new bacteria has entered the coal after the coal has been deposited and formed. The bacteria would need to have originally come from the surface in order to get the C14 from the atmosphere. How can bacteria from the surface travel down to coal beds, which are on the order of hundreds/thousands of feet deep? The same problem holds for oil. And also for diamonds.Goat wrote: Yes, that is true, and do you know WHY it is true?
Lests say you have 10 balls. You drop them one after another and they all fall to the ground. You go to drop the tenth one and amazingly, it goes up to the ceiling.otseng wrote: If the assumptions of carbon dating are true, then the more reasonable answer is that the ages are accurate.

This whole statement is nothing more than an argument from incredulity. The answers are out there. There evidence is there. The wiki article has citations. Why would you, once again, dismiss a claim before trying to read the evidence? You only read vague claims in a wiki article, not the papers which make these claims themselves.So, "bacteria" or "other unknown secondary sources of carbon-14 production" is posited.
