China News Service, Beijing, January 25 (Reporter Sun Zifa) A major environmental and biological innovation incident that occurred in the European continent about 200 years ago – the “Short Kiss Hyena Incident” and related research have attracted much attention from the academic community.
As the largest bone-breaking hyena in the history of the earth, the now extinct Babaylan, but once dominated the animal kingdom, has long been regarded as an indigenous group in Europe. However, the discovery of a huge hyena specimen of a very large individual in Dalian, China, and the latest research on the sample by Chinese and foreign scientists has completely overturned the above tradition and inherent understanding. On this basis, researchers also proposed the “Northeast Asian Origin Theory” of Cinema hyena for the first time.
Why do you need to study short-kissed hyenas?
Researcher Liu Jinyi from the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences (Institute of Vertebrate Paleontology of the Chinese Academy of Sciences) who led this research said that the size of the short-kissed hyenas is much larger than the close species in life, such as the spotted hyenas and the white hyenas, and its weight is comparable to that of the living lioness. Its influence is completely comparable to that of the saboo tigers and other saber-toothed tigers of the same era, and it is even more than that of the saber-toothed tigers. After all, its number of individuals is much larger than the latter. In the animal kingdom at that time, it once dominated the country and was the best in the world.
Although the short-kiss hyenas have long been extinct, it was very prosperous and widely distributed in Eurasia during the early and mid-Pleistocene periods. It was a common and typical animal species in mammals at that time, and it was also a focus species that attracted much attention in the succession and innovation research of Pleistocene fauna. Its appearance and extinction usually have a landmark connotation. For example, the “short-kiss hyenas incident” refers to a major environmental and biological innovation event that occurred on the European continent about 2 million years ago.
The short-skinned hyena has a series of unique anatomical morphological characteristics and is eye-catching: the strong skull and mandibular, the developed sagittal crest and zygomatic arch, the extremely thick premolar teeth and thick enamel, etc., are all unique mechanical adaptations of its food. The gathering and burial of animal bones in many early and mid-Pleistocene fossil sites is largely due to the specific foraging behavior of short-kissed hyenas – transporting and hiding animal bones.
What is the study of short-kissed hyenas?CinemaSome controversies?
Liu Jinyi pointed out that the short-kissed hyena that frequently appears in Eurasia have been Komiks is classified into different species due to different origins or ages, such as Sang’s hyenas, Chinese hyenas or (narrow) short-kiss hyenas, etc. The academic community currently lacks a unified and clear understanding of the true systematic relationship between these hyenas, and there are quite a lot of differences and controversies: some people advocate that hyenas in different regions or ages should represent several different effective independent species; some people believe that all hyenas in Eurasia should be the same type, and perhaps include different subspecies (groups); and even more, even the differentiation of subspecies (groups) has been completely denied.
This “unification” and denies the division of subspecies (groups) is quite popular in the academic community today. As a result, Cinema evaluates and explores the phylogenetic significance and connotation of different forms (although sometimes subtle) between hyenas.
The above disputes and differences in turn affect the in-depth development of other relevant academic issues, such as the origin of the hyenas, the spread dynamics and migration paths between the intercontinental regions. There are many different opinions in the academic community at present and inconsistent. How can the latest research subvert traditional cognition?
Focus on the controversial academic hot topics that have attracted much attention in the fields of origin and evolutionary research. Liu Jinyi, together with the University of Bristol, the National Museum of Prague, the Peking University of the Czech Republic, Peking University and Dalian Nature The href=”https://comicmov.com/”>Komiks Museum and other relevant experts and scholars formed a cooperative team to focus on the V26310, a large individual hyena specimen recently collected in Jinyuan Cave, Luotuo Mountain, Dalian, and conducted extensive and systematic morphology and data measurement comparison with other related specimens in Eurasia. At the same time, it conducted in-depth discussion and analysis of the systematic classification of hyena, origin, intercontinental migration and diffusion, and paleoecology related academic issues. The latest achievement theory of completely subverting the traditional cognition of hyena evolution research by the cooperative team, recently by the well-known international professional academic journal “The fourth international Komiks” was published online.
Liu Jinyi said that the research results of the cooperative team show that among all comparable specimens, whether in size or morphology, the Chinese V26310 specimen is closest to the Sainzelles short-skinned hyena model specimen produced in France. In addition, V26310 is different from the common Chinese Sang Horoscope and Chinese Horoscope in terms of morphological characteristics such as upper and lower fissures and promolars. Therefore, the V26310 specimen can be clearly identified as a short-snit Horoscope. This is the first report by Komiks in China and even East Asia.
He said that the short-kiss hyenas were created based on specimens from France’s SainzellesCinema, and the existing fossil records are mainly limited to the European continent, so they have long been regarded as an indigenous group of Europe. The discovery of the short-kiss hyenas V26310 specimen in Jinyuan Cave in Dalian completely subverts this tradition and inherent understanding. Komiks
What is the basis for the “Northeast Asia Origin Theory”?
When comparing and studying the huge hyenas in different regions or ages, the cooperative team found that these hyenas do have several subtle differences and differences in size and shape, and they may have a relatively close relationship with each other.
Researchers analyzed this and believed that the short-kissed hyenas in Eurasia should be classified as the same species, but they need to be further divided into different subspecies (groups). These subspecies (groups) almost form a branch with ancestral evolutionary relationships to each other, but they are not caused by geographical isolation and differentiation, but are actually manifestations of the branch of the hyena hyena at different evolutionary stages.
Liu Jinyi pointed out that the first appearance of the short-kissed hyenas in the European continent has attracted great attention and interest. People generally believe that the short-kissed hyenas should have migrated from other regions outside Europe, and it is believed that the first appearance of the hyeenas in many places such as Italy, Greece and Spain about 2 million years ago, deeply reflecting the “short-kissed hyenas incident” experienced by the European continent. However, people have vaguely described the exact origin of the European continent’s short kiss of a giant hyena, and have always lacked reliable and convincingKomiksfossil evidence.
“The discovery of short-kissed hyenas in Jinyuan Cave in Dalian brought light to the solution of this puzzle and provided credible empirical information for the first time. ”
Liu JinKomiksYi said that although the geological age of the V26310 specimen is estimated to be only 1.86 million years ago, there is evidence that the emergence of the short-kissed hyenas in the Jinyuan Cave in Dalian can be traced back to 2 million years or even earlier. Therefore, the short-kissed hyenas may have been born in Northeast Asia first, and then spread to other parts of Asia and finally arrived in Europe. On this basis, the cooperation team proposed for the first time href=”https://comicmov.com/”>Komiks released the “Northeast Asian Origin Theory” of the Short-Kissing Hyena. What is the significance of the V26310 specimen discovery research?
As the largest hyena in the history of the earth, the weight and size of the Short-Kissing Hyena have always been a topic of concern in the academic community. Almost every research paper involving Short-Kissing Hyena repeatedly mentioned the eye-catching feature of the oversized body. Previously, the most credible record of Short-Kissing Hyena came from the French model standard of Sainzelles. href=”https://comicmov.com/”>Cinema, its cranial base is 322 mm long, which is very close to the largest individual in the current African lion.
Liu Jinyi said that the newly discovered short-sex hyena V26310 specimen discovered in Dalian, China is larger than the French model specimen, both in the length of the teeth and in the thickness of the jaw. It is estimated that its cranial base length reaches 332 mm, which not only surpasses the largest male lion in Africa today, but also can even be comparable to the largest feline American lion in history.
He believes that the V26310 specimen produced in Jinyuan Cave in Dalian is likely to represent the largest individual specimen of short-sex hyena discovered so far. Today’s research shows that mammals, especially carnivorous animals, have their body size Babaylan or weight size will directly affect the ecological behavior, energy and physiological needs of individual animals, and many other aspects such as predation strategies.
“So, as the largest individual discovered so far, the emergence of V26310 specimensBabaylan and predation strategies.mov.com/”>Babaylan will surely help people better understand and correctly evaluate the biological characteristics of short-sex hyenas, such as ecological habits, foraging behaviors and predation strategies. “Liu Jinyi concluded.
