Male seahorses give birth because they have evolved a remarkable form of male pregnancy. During mating, a female transfers her eggs into the male's specialized brood pouch, where the eggs are fertilized and the embryos develop. The father protects the developing young and helps regulate their ox...
Yes, birds are dinosaurs. Modern birds are the only surviving branch of dinosaurs and evolved from small, feathered theropod ancestors during the Mesozoic Era. Scientific evidence from fossils, skeletal anatomy, feathers, eggs, and evolutionary relationships establishes that birds belong within the...
When people say “flying dinosaurs,” they usually mean one of two things:True flying dinosaurs = birds (the only dinosaurs alive today).Dinosaur relatives that flew = pterosaurs (often mislabeled as “flying dinosaurs,” but not dinosaurs).And then there’s a third, fascinating middle ground: non-b...
1. Archaeopteryx specimens, gradient, evolution from dragon to bird As more and more feathered dinosaurs and primitive bird fossils are discovered, scientists have found that there are more and more similarities between the two, such as body structure (size, bone healing...
What would daily human life be like without numbers? hard to imagine. What about the animal world? Research over the past few decades has found that animals have the same "number sense" as humans and can use the concept of numbers in life; this number ability is not based on language abili...
Among the elephantoids, the main group of proboscis, the development of a pair of huge upper incisors (ivory) has become a distinctive feature of this group. This structure is often used as a feeding tool for individuals and as a weapon for males to compete for mating rights. Pr...
There are two types of mules. The species produced by the mating of a male donkey and a female horse is called a horse mule. The species produced by the mating of a male horse and a female donkey is called a donkey mule. They are both referred to as mules. As a cross between a horse and a don...
A research paper suggests that dinosaurs may have evolved wings and feathers earlier than before. In a detailed study of Edmonton Ornithomimosaurus fossils, scientists found wing-like forelimbs and hundreds of filament-like marks that suggested they had feathers. There has been new progress i...
Ancient fish that lived 436 million years ago swam flexibly in the ancient ocean. This was restored by Chinese researchers based on a batch of fish fossil specimens discovered in the Chongqing Special Buried Fossil Library and the Guizhou Shiqian Fossil Library. scene. Among the newly discovered fos...
Eight million years ago, soft, boneless creatures first evolved into fish with internal skeletons. Fish then evolved into amphibians that walked on land, and then evolved into reptiles. One of these reptiles evolved into archosaurs. The earliest dinosaurs were small, bipe...
On February 1, Wang Min, Zhou Zhonghe, Zou Jingmei of the Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, and Pan Yanhong of the Nanjing Institute of Geology and Paleontology reported in Nature Communications a discovery of 130 million The Early Cretac...
Zhu Min’s team at the Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences has made new progress in the field of early vertebrate animal research. On March 8, the magazine "PLOS ONE" reported the latest scientific research results of Dr. Chu Bulan and other...
The Qinghai-Tibet Plateau has a vast territory and high terrain, and is known as the "Roof of the World". The formation of the Tibetan Plateau was caused by the collision of the Indian and Asian plates (about 50 million years ago). However, scientists have very different understandings of how...
On May 2, a research team composed of paleontologists from various research institutions in mainland China, Hong Kong, Canada and other places reported in the journal Nature Communication a species that lived about 125 million years ago. Dinosaur of the year - Jianianhualongs tengi. This is a...
For a long time, gomphotheres have been considered a central link in the evolution of proboscis. The origins of Rhynchotheres and Cuvieroniines are more or less related to codons. However, Codon is also considered to be a problematic genus and a garbage bin group in the evolutio...
On August 30, a scientific research team composed of researcher Xu Guanghui from the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences and researchers from many research institutions in the UK and the United States published a paper in...
