Chicken With Dinosaur Features Has Been Created by Scientists

The 'chichenosaurus' story made its way into the research community last week when scientists announced they had modified the beak of a chicken embryo to resemble the snout of a large large dinosaur. . But while some experts have praised the show, it's just one of many modifications that need to be made to turn chickens into dinosaurs.

Given this problem, how do scientists find dinosaur chickens?

Jack Horner, professor of paleontology at Montana State University and curator of paleontology at the Rocky Mountain Museum, says, “By far the most common, we're at 50 percent.

Horner has long supported the idea of ​​turning chickens into dinosaurs, and unlike modern science scientists, he certainly wanted to raise chickens. And why stop? Many mutations can be made by understanding how and when to alter specific molecular processes. As Horner points out, glow-in-the-dark unicorns aren't a problem.

Horner said four major mutations would need to be formed to develop the so-called kinecosaurus. In order to turn a chicken into a dinosaur-like creature, scientists had to remove their teeth, long tail, and put their wings back on their arms and hands. The animal may also need a mouth modifier, he said.

"This dinosaur project can be compared to the lunar project," Horner told Live Science. "We know we can do it. There are just... a few big problems."

One of the "major issues" discussed in a recent study was published May 12 in the book Evolution. In this study, scientists replaced a chicken's beak with a dinosaur's snout. But even that seems small worked for seven years. First, the scientists studied the growth of chicken and emu embryos and the snout growth of turtle, crocodile and lizard embryos. Millions of years ago, birds and reptiles would have had a similar way of developing snouts, but over time molecular changes caused the bird's beak to develop, the scientists said.

Obtaining embryos from modern animals such as crocodiles is difficult for scientists to compare because they have to find farms to raise them. And then molecular research (which determines which growths are different, how they differ, and how to control them) "requires hours and hundreds of experiments for some comprehensive methods," said research director Bhart-Anjan. Bhullar is currently a student at the University of Chicago and will begin as a full-time professor as a paleontologist and developmental therapist at Yale University. "It's like finding bones."

For "fossil discovery", scientists need fossil data on birds and their ancestors to determine what birds look like at different stages of evolution.

"You have to understand what you're tracking before you can track it," Bhullar told Live Science. bular; Arkhat Abzhanov, his PhD consultant, biologist at Harvard University; And their team zeroed in on two genes that work in the face. Each gene codes for a protein, but the protein that generates the gene activity indicates different activities in modern embryonic development of chickens and animal reptiles, the researchers found. While scientists blocked the activity of these two proteins in chickens, the birds developed a snout-like structure rather than a beak.
