It's perfectly possible that the nests found inside the fossilized trees were made by bees 200 million years ago. The arguments used by the skeptics are not convincing.
First, it's true we have no fossil remains of actual bees that date to 200 million years ago, but maybe the reason for that is that bees could not be preserved as fossils at that time. Fossil bees have typically been preserved in fossilized tree resin, a sticky liquid produced by trees. However, trees with this type of resin were very rare 200 million years ago. Such trees became common much later. So the fact that we have no bee remains that are 200 million years old doesn't mean that bees did not exist at that time. Maybe bees existed, but since there were almost no trees producing the right kind of resin, the bees could not be preserved.
Second, while it's true that bees ha ve a close mutual relationship with flowering plants today, it's quite possible that bees existed before flowering plants appeared on Earth. Those very early bees might have been feeding on non flowering plants that preceded flowering plants during evoluti onary history. The early bees could have fed on non - flowering plants such as ferns or pine trees. Later when flowering plants evolved, bees may have adapted to feeding on them! And this new relationship between bees and flowering plants may have remained stable ever since.
Third, even though the fossilized chambers lack spiral caps, there's chemical evidence that supports the theory that bees built the chambers.
Modern bees protect their nest chambers against water by using a special waterproofing substance that has a distinctive chemical composition. When the fossilized chambers were chemically analyzed, it turned out that they contain the same kind of waterproofing material that's used by modern be
The reading states that the old fossils that have been found in Arizona's trees are not resembled bee nests and provides three reasons to support it. However, the professor explains that it is possible that bees' fossils were found inside old trees and refutes each of the author's reasons.
First, that there are no actual fossils of bees related to 200 million years ago, as reading claims, is rejected in the lecture. The lecturer says that bees needed a specific kind of liquid produced by trees called resin for the preservation of their fossils in the trees. Likely, 200 million years ago, the resin was rare and did not produced by trees as much as todays' trees do and became common later. In other words, bees would not have access to the right kind of resin 200 million years ago.
Second, based on the reading, 200 million years ago, there were no flowering plants for bees to associate with them. In contrast, the professor says that bees existed long before flowering plants. According to the professor, bees had a biological relationship with other kinds of plants such as ferns and pine trees. After flowering plants evolved, bees adopted with them.
Third, the author points out that bees' nests lacked finer details related to modern chambers made by moderns bees. The professor casts doubt on this point by explaining that these chambers are made by specific chemical materials produced by bees. There is strong evidence that supports bees in the past produced this kind of chemical substance. Also, this material has been like modern bees material and was waterproof.
