Did bees (a type of insect) exist on Earth as early as 200 million years ago? Such a theory is supported by the discovery of very old fossil structures that resemble bee nests. The structures have been found inside 200- million-year-old fossilized trees in the state of Arizona in the southwestern United States. However, many skeptics doubt that the structures were created by bees. The skeptics support their view with several arguments. No Fossils of Actual Bees First, no fossil remains of actual bees have ever been found that date to 200 million years ago. The earliest preserved body of a bee is 100 million years old—only half as old as the fossilized structures discovered in Arizona. Absence of Flowering Plants A second reason to doubt that bees existed 200 million years ago is the absence of flowering plants in that period. Today's bees feed almost exclusively on the flowers of flowering plants; in fact, bees and flowering plants have evolved a close, mutually dependent biological relationship. Flowering plants, however, first appeared on Earth 125 million years ago. Given the bees’ close association with flowering plants, it is unlikely bees could have existed before that time. Structures Lack Some Details Third, while the fossilized structures found in Arizona are somewhat similar to nest chambers made by modern bees, they lack some of the finer details of bees’ nests. For example, chambers of modern bee nests are closed by caps that have a spiral pattern, but the fossilized chambers lack such caps. That suggests the fossilized structures were made by other insects, such as wood-boring beetles.
The passage and the lecture are about the longevity of presence of bees on earth. While the passage casts doubt on the claim that bees existed 200 million years ago, the lecturer refutes author's ideas and believes that it is possible for bees to exist as early as mentioned.
To begin, the reading points that no fossils of a bee body has ever found which goes back to 200 million years ago, and the oldest preserved fossil is about 100 million years old, only half of the claimed number. On the contrary, the speaker maintains that the bee body is not likely to be preserved for a long time, unless there are special circumstances. In fact, in order to have a preserved body of a bee, the corpse should be preserved in a rasin of a special tree, and those trees were rare back in 200 million years ago. it is possible that later on those trees became common and their presence eventuated in the creation of 100 million years old fossils.
Secondly, the passage contends that since bees nutrition is dependent on flowering plants, in the absence of those plants bees are unable to feed and live; the situation which was prevalent 200 million years back from now. However, the speaker gainsays author's reasoning by mentioning the probability of bees being independent from flowering plants in the past. She explains that although the realtion is strong today, bees used to feed on non-flowering plants like pine trees, before the evolution of flowering species. To clarify, the intimate relationship of bees and flowers began after the emergence of the flowering plants, and has been strengthened since then.
Finally, the reading asserts that found fossils lack details on spiral patterns in caps and they cannot belong to bees. The woman undermines is against that argument and notes that although the missing details exist, there are some remenants of waterproof materials in the found old hives. those distinctive materials are being used today by bees to fulifill the exact purpose. So it is possible to claim that the 200 miliion years fossil belongs to ancient bees.
