Right in front of Zheng Zha's and Li Xiaoyi's eyes, it's a dragon! Western-style dragons! With a body like a large lizard, two bat-like wings on its back, and a body more than 30 meters long, supported by four strong dragon claws, quickly chased towards the Tyrannosaurus rex in front of it, and bit off the head of the Tyrannosaurus rex in one bite.

Looking at this giant dragon, Li Xiaoyi can imagine how many paleontologists, biostructurists and biomechanics in this world will hang themselves because of it, and how many people will go crazy because of it, because the unscientific force field on this dragon will blind Li Xiaoyi's 24K krypton gold.

The length and weight issues mentioned above are ignored, and the speed of movement is not taken into account, what is the matter with these four claws and a pair of wings?

You must know that except for insects and crustaceans, all long-legged creatures on the earth are four-legged, and those with wings are two-legged, such as birds, two-legged, and the forelimbs have evolved into wings; bats, two-legged, forelimbs evolved into wings; Human, two-legged, forelimb evolved, hand, this does not count.

This is because although living things mutate all the time, not all mutations can play a role. Some "shallow" properties are easy to change, like a house with more pigment and less tiles, which has little impact; But some attributes are "deep", and they affect the whole body, like the beams and pillars of a house, and such attributes are difficult to change. Evolutionary biologists liken this phenomenon to "canalization": traits can't flow out as if they were confined by canals, small mutations can't have an impact at all, too large mutations can cause the entire canal to break, and the organism dies, making a smooth transition from an established developmental framework to another almost impossible.

For example, the "recurrent laryngeal nerve" that all vertebrates have, for humans, is mainly responsible for speaking and swallowing, and how the nerve that controls the movement of the throat is wired, it extends from the brain stem, and extends down the cervical vertebrae to the heart as if it is not visible. Bypassing the aorta and then turning back, the whole whole circle from head to chest to throat, and then considering the conduction speed of the nerves, so it is said to drink water and spray on the face. It's really not intentional to spray a table when eating, it can only be said that it is a creation to make people.

The giraffe said, have you considered my feelings, I'm going to go around 4.56 meters. If you take it out, you can use it as a skipping rope for Yao Ming......

And the Brontosaurus family, sauropod dinosaurs, who have just been overturned by the Death Legion on Sona Island, are just a representative, the super dragon circled 28 meters, which is equal to the length of a basketball court in Yao Ming's game, and the longest fragile double-chambered dragon may have circled 38 meters, which is the circumference of half a basketball court!

Why, because this nerve was inherited by vertebrates from their ancient common ancestors, fish ancestors, for fish, the recurrent laryngeal nerve aligns with the blood vessels. It's all distributed in the gills, which is natural.

However, with the continuous evolution of organisms, the position of the blood vessels in the gills gradually moved back, and the recurrent laryngeal nerve and blood vessels are the same, so it can only honestly move backwards; The gill arch (gillarch) attached to the other end evolved into the throat (larynx).

As a result, the recurrent laryngeal nerve can only be tragically detoured for a long time, because if it comes out independently and opens a special line, its efficiency is improved, but at the moment it is disconnected. The creature is finished, and it is impossible for it to survive evolution.

And if that's not enough, do you know how many cervical vertebrae a person has? Seven pieces. How many giraffes are there? It's also seven pieces. How many pieces does the rat have? Or seven!

You see, whether it is such a small recurrent laryngeal nerve that is so difficult to deal with, or a cervical vertebrae with a huge difference in length. Without exception, they all follow the principle of "canalization", how did the dragon grow two wings while growing four legs?

If you directly say that it is a magical creature, it would be okay, but the research notes actually say that it is caused by the fusion of the biological gene chain, which is not the fusion of the gene chain at all, and the gene lotus will not change its shape and expression if it is fused. Even if the mouse was given an improved sparrow's wing gene. It will only become a creature with sparrow wings and rat hind legs, and will never become a mouse with wings, because the relevant genes are modified and expressed for the forelimbs, unless you first make the mouse grow four front paws, two of which will grow on its back!

Therefore, this dragon with limbs and a pair of wings is simply the product of genetic invention and recreation, and the scientist who wrote this research note is so unreliable that it is no wonder that he is called a "mad scientist", this guy can't even do basic research notes!

And just when Li Xiaoyi was frantically complaining, the voice of the main god sounded again, saying that after having Chu Xuan, the workload of this main god increased several times......

"Jurassic Park II Lost World Side Plot, kill the dinosaur mutant, the person who kills will get a B-level side plot number, reward points 5000, and the team members who assist from the side will get a C-level side plot with a reward point of 4000, this creature is a legendary magic creature, high-tech long-range weapons are neutralized, and if the creature cannot be killed within 24 hours, all team members involved in the attack will be wiped out."

Zheng Zha, Li Xiaoyi, while listening to the hint of the main god, quietly watched the giant dragon biting the body of the Tyrannosaurus rex, and as soon as they raised their heads, they tore apart the entire upper body of the Tyrannosaurus rex! That's a few tons of meat, otherwise you buy two catties of pork and go home to tear it up, which hasn't allowed you to buy pork ribs.

Then, the two of them turned around and flew in the direction they came, this main god is too ferocious! Not far after flying out, the roar of a giant dragon could be heard behind him, and the sound was extremely loud, not much better than the Overlord's pulse catapult gun.

When Zheng Zhan returned to the position of Chu Xuan and the others, Li Xiaoyi had already arrived, the mobile armor was flying relatively fast, and everyone was surrounding him to ask what the roar was just now.

Seeing that Zheng Zhan had also returned, Li Xiaoyi told everyone what had happened just now, as well as the hint of the main god, the overlord and Wang Xia heard that there was really a giant dragon, and they couldn't believe it for a while, and Chu Xuan lowered his head and began to think after listening, as for Zhao Yingkong, he just took out the "Scattered Night Double Blade" and wiped it carefully.

Li Xiaoyi noticed that Luo Gandao's eyes were wandering, he should be trying to find a way to slip away, but unfortunately he knew that Li Xiaoyi could remotely control the "Dinosaur Express Kesai", even if he could run for a while, he couldn't run for a lifetime. (To be continued.) )
