Do you believe that gene mutation causes birds to have no teeth?

Studies, birds, gene mutations, genes, 1 of all animals on earth, birds, anteater, baleen whales and turtles and so on seem to have no relationship, but they all have a very similar place-there are no teeth. And the bird's mouth is the most special, and all the animals are not the same, but you believe it? Birds are not born without teeth. A new study found that the ancestors of all birds had a pearl-like tooth 116 million years ago, and the sharpness of the teeth could even be comparable to dinosaurs! Does it sound scary, and it's unbelievable? In the study, researchers looked at mutations in modern bird tooth genes to explore how birds evolved-without teeth. However, there are few evolutionary data that can be consulted, but only through the fragmented fossil records left by ancient birds, but the genes of modern birds can help discern birds lose their teeth over time. So unlocking the hidden DNA secrets of birds is an important way to understand the history of bird evolution. Springer, a biology professor at the University of California, is one of the main researchers in the study. He argues that modern birds help them to process and digest food through curved beaks and robust digestive tracts, but the "Archaeopteryx" fossil bird, discovered in Germany in 1861, suggests that the birds ' ancestors were crawling teeth. Professor Springer that scientists now know that birds evolved from animal foot dinosaurs, which evolved from predators such as Tyrannosaurus rex, with a mouthful of sharp teeth. But no one knows what has happened that has caused the birds ' teeth to turn into the present, so the history of modern birds ' teeth shedding has been a mystery for more than 150 of years. In a recent study, the researchers speculated that birds lost their teeth in a particular event. To find out, they investigated genes that control the growth of teeth, and found that six of the genes involved in vertebrates were critical to the formation of teeth. The researchers looked for genes that could be mutated from these six genomes in 48 species of birds, which cover almost all birds. It turns out that the mutation of teeth and the lack of teeth are almost always found in all birds, suggesting that their common ancestor has long lost the ability to form teeth. The researchers also found that 48 species of birds had the same dentin mutation and tooth-missing genes, suggesting that birds began to lack teeth about 116 million years ago. The researchers also studied other vertebrates that did not have teeth, and found the same mutant genes in turtles, armadillo, sloth, soil dolphins and pangolin that looked like scaly anteater. We can hardly imagine the sight of birds having teeth. Imagine, back home ready to tease a bird cage in the parrot, the result of its mouth is not a graceful cry, but is a chilling fangs teeth, you are interested, have the courage to interact with it happily? So we have to rejoice that it is because of the genetic variation of birds that we can hear all kinds of wonderful sounds and feel the birds are lovely and interesting, noEvery day we worry that birds from the sky will take our piece of meat.
