I doubt that this is true. I find scientists are usually quick to assume things which are not true, and only over time is it shown that they have things totally backwards.
This is one reason I find carbon dating to be questionable.
Absurd comment. "scientists?" That's a very vague, general term that includes possibly hundreds of different fields. In this case we are talking about archaeologists, and findings in that field moreso than many others, are clearly open to interpretation. In particular, there is an obvious logical fallacy in drawing their conclusion about camels - Just because the earliest find they have SO FAR is dating back to this particular time period, does not mean there are not earlier camel remains which they haven't found yet. Some new discovery could come along and find camel remains in the region from centuries earlier. Absence of evidence, especially with regard to sparse archaeological findings, is not evidence of absence. That does not require the denial of basic chemistry in disputing carbon dating. It just requires a brain.
More than that, some of their statements reflect their biases. Not shown in this article, but they do find earlier dated camel remains but insist these were not domesticated or not yet capable of heavy lifting. So they presume to know precisely which camels Avraham and the egyptians used and that this type is not what is described in the Bible? This is where archaeologists have exited their own field in drawing conclusions about their work - always a red flag!
The science behind carbon dating is not "questionable" except to someone who dogmatically denies its conclusions.
