[Scientific Research Progress] West Liaoning found a new quilt plant fossil

Author:Chinese Academy of Sciences So Time:2022.07.15

A century ago, British botanists laid the foundation of the quilt plant system based on Magnolia. Magnolia's separated heart skin was used as the most primitive pistil type in the quilt plant. From the perspective of fossils, almost all the hearts of the early quilt plant fossils discovered before were born, so the doctrine seems to have a certain rationality. However, with the constant discovery of the fossil evidence, there are two doubts to botanists: First, the recording of quilt fossils recognized by the mainstream botanical community is not before the early white world. Plants have high diversity, which is not logical; the second is that the form of some early quilt plants far exceeds the prediction of British scholars theory.

Recently, Biology, a professional academic magazine published in Switzerland, published the paper "A New Early White Flower and its Apocalypse for Flowers" by Researcher Wang Xin, a researcher at the Nanjing Institute of Geological Palace of the Chinese Academy of Sciences. The problem provides a new perspective.

Lingyuan Qi Qi (LingyuananNTHUS InExpectus) mode specimens and details

The article reports that the faint stone, which was completely different from the previous quilt plants, is Lingyuananthus Inexpectus. The reason why it is named Ling Yuan Qi Qi is that although Ling Yuan Qi Qi was early (125 million years ago), it could not see the botanist's expected separation of heart skin, but on the contrary, it has evolved Features, such as the skin of the heart, the lower sub -room, the flower tray, and the possible symmetry on both sides. The previous point is confirmed that the theory of popular plant evolution is defective. It cannot explain the reality of botanical reality and needs to be adjusted; the later point brings new revelation to botanists. The flower brackets here are often seen in daily life. Taking Apple as an example, the favorite, sweet and sour, nutritious part of the most favorite, sweet and sour, and nutritious parts in Apple grows from the flower tray in the apple flower.

According to the theory in the textbook textbook, the pistil composed of the synthetic skin is healed by the original multiple lover -hearted skin, not the most primitive. The emergence of Ling Yuanqi in the early white world shows that not only the quilt plants had high diversity at that time, but also imply that the quilt plants should be existed in the early white world or earlier. And depression.

As early as sixty years ago, German ancient botanist Zimmermann proposed a similar theory, because of the lack of corresponding fossil evidence support at the time, it could only be left. In recent years, based on the results of the study of modern plants, Wang Xin also proposed that there are similar claims in several origin of the pistils of quilt plants. The emergence of Ling Yuanqi confirmed the predictions of these two doctrines.
