Scientists have long believed that bees existed up to some 200 million years ago. This notion has recently come under some speculation because of a lack of any significant evidence to support this theory. Key missing evidence includes fossil records, the lack of flowering plants to support bee life, and recently revealed discrepancies in the fossil record.
To date, the oldest known bee discovered is a 100 million-year-old specimen preserved in amber. This ancient specimen, trapped in tree resin, is at least 35-45 million years older than any other known bee fossil. What is concerning scientists is the lack of any fossil evidence older than 100 million years. Fossil records for other plant, animal and insect species are quite complete, however, the bee is missing a similarly lengthy record.
The ancient world lacked flowering plants. This is important because bees are pollen-dependent and rely on flower pollen and nectar for energy, protein and other nutrients. Flora in the ancient world 200 million years ago were mostly dominated by conifers which did not flower or produce the pollen and nectar necessary for bee survival. Lacking this food source, it is highly skeptical that bees could have existed 200 million years ago.
Several of the fossil records being studied by scientists have also brought to light major discrepancies that exist between modern beehives and beehives of the ancient world. Specifically, ancient beehives seem to have a different organization and structure compared to that of modern beehives. This variance in evidence in the fossil record has led experts to speculate that these fossils are not fossils of beehives, but rather nests of another insect species.
The passage brings up the long belief among scientists that bees existed up to 200 million eego. The writer, then, deliberates deeply on three reasons that there is no evidence supporting this theory. However, the speaker finds the stated reasons irrational and refutes each of them with compelling reasons.
First and foremost, the article asserts that the oldest bee fossil found in tree resin dates back to 100 million years, and there is no other evidence. On the other hand, The professor clears out that in ancient times trees did not exist so as to bees were not preserved in tree resin but they were under layer and layer of sediments that bees escaped from fossilizing.
secondly, the reading claims that in ancient times flowers, which bees depended on their pollen to survive, were not on the face of the earth, no bees back then. Conversely, the lecture points out that bees found other sources of food such as tree honey doo. Thereby, they were not dependent on flowers.
Last but not least, the passage mentions that modern beehives are differentiated from ancient ones by their organization and structure. Consequently, scientists are in doubt whether discovered fossils are related to modern bees. The speaker, whereas, reveals that chemical analysis proves that both modern and ancient beehives are the product of the same bees, and their dissimilarities are due to evolution and adaptation.
