Drawing snakes and adding feet to the metaphor of doing superfluous things is not only useless, but inappropriate; it is also a metaphor for fictional facts, which are made out of nothing. The story of painting snakes and adding feet has also been ridiculed by the world. But the owners of stories that have been ridiculed by the world may be confirmed by the latest discoveries by scientists, who are not only not wrong, but may also be considered prophets. Why?
Based on the newly discovered ancient snake fossils, the research team of Yale University in the United States conducted in-depth research on snake genes and anatomy, and compared them with modern snakes. During the study, paleontologists mapped a genealogical tree that included both extant and extinct snakes, making the evolutionary patterns of snake history more clear.
Scientists have long had two views on the ancestors of snakes: one is that the ancestors of snakes were aquatic animals, because the current snake is very similar to a now-extinct aquatic giant lizard called Mossa dragon from a biological point of view; the other is that the ancestors of snakes were terrestrial animals, which originally had feet, which later degenerated and disappeared.
The Yale University research team compared the DNA of 17 modern snake species with 19 aquatic lizards and found that they were not related by blood, thus ruling out the possibility that the ancestor of the snake was a Mossaurus.
Snakes evolved from four-legged ancestors, and scientists have long wondered how they lost their legs. Now, researchers have conducted an X-ray tomography (CT) scan of a 95-million-year-old fossil that reveals how genes hinder the development of limbs. Scientists point out that the snake is very similar to modern terrestrial lizards, and this result helps to unravel the mystery of the origin of the snake.
Large terrestrial lizard reptiles have feet, so it can be concluded that the ancestors of snakes also had feet, and it seems that sometimes it is not necessarily wrong to draw snakes to add feet.
