开启了鱼类登陆,并最终演化成为其他动物——包括人类的进程。 “These fossils provide an unprecedented opportunity to peek into the ‘dawn of fish’ 朱敏院士说,“这些化石为我们一窥‘鱼类的黎明’提供了前所未有的机会, and help scientists trace many human body structures back to these ancient fish, 还...
Much less widely appreciated are the diverse additional ways that fish have contributed to human societies. Here, we explore the assorted uses of freshwater and marine fishes, both presently and in the past, by focusing on their contributions to manufacturing and industry, technology, health care,...
They evolved from fish. Not long ago, some Chinese scientists found five fish fossils (化石). The fish are about 436 to 439 million (百万) years old. What is special about them? Well, they have jaws (下颌).Jaws are important for human evolution. With jaws, ancient fish could bite and...
The fossils "help to trace many human body structures back to ancient fishes, some 440 million years ago, and fill some key gaps in the evolution of 'from fish to human,'" researchers from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) under the Chinese Academy of Scienc...
Well, they have jaws(下颌).Jaws are important for human evolution. With jaws, ancient fish could bite and chew. They got more food and evolved faster. They came out of the water and evolved from swimming to crawling(爬行) and then to walking. But for a long time, scientists didn't ...
TAIYUAN, June 1 (Xinhua) -- A new study conducted by scientists from China, Sweden, and the United Kingdom reveals that the human middle ear evolved from fish gills. According to Gai Zhikun, a Chinese Academy of Sciences researcher and the first author of the article "The Evolution of th...

Researchers at University of California San Diego School of Medicine and in Japan have used an ancient fish to reel in new insights about human biology and, in particular, how and why a widely used medication works to abort pregnancies (in people, not fish). ...
Alternatively, the rhizodonts may be more closely related to the four-legged animals and the elpistostegids than we thought. But this would also imply a certain amount of independent evolution of similar features, because the rhizodonts would then sit between two groups that have many ...
