Chapter 120 Hitting the mark
Just like that, you agreed?
Gu Qingyuan felt that although he was old, his hearing was not bad at all, and he still walked with great vigor.
But at this moment, Gu Qingyuan really began to doubt whether he was too old. He turned to look at Wu Gang who was in a daze and repeated it.
"He agreed?"
Wu Gang swallowed and nodded.
It's so unexpected.
The other person's answer is without hesitation, just like when mom asks what you want to eat in the evening, the answer can be as easy and casual.
Are there really such people?
Are you born adventurous and not afraid of death at all?
【Wait! Wait a little longer! 】
[There are too many uncertainties about this fact, and we have too little information about this creature.]
[I think we should discuss this further…]
Gu Qingyuan sent the message quickly. He was impulsive just now and didn't expect the other party to agree so easily. Now that he has calmed down, he feels conflicted.
This is too dangerous. It's as difficult as catching a wild crocodile, no, even more difficult!
At present, people's research on crocodiles is very mature, and the weaknesses and habits of these creatures are very clear, but this one is a completely unknown creature!
Everybody is blind!
You have no idea how fast it runs, how strong its bite force is, whether it is active at night or not, where its weaknesses are, how well it defends itself, or whether it hunts in groups.
The only small amount of information we have is the short video of less than three minutes last night, which is not enough!
"That's enough." Bifang took off his jacket, smiling, his tone full of excitement, "I beat it away last night, that's enough, isn't it?"
Gu Qingyuan was stunned.
These words are unrestrained and uplifting, like the morning sun in spring.
That natural and friendly smile, which shows the confidence that things are firmly in hand, is enough to infect everyone.
Gu Qingyuan looked at Bifang on the screen, as if this young man was a tiger in the wilderness, and he had an irresistible urge to bow his head to him!
Even living fossils that existed billions of years ago are no exception!
He shook his fingers and deleted the message he had just wanted to send, changing the original dissuasion into an instruction.
【Be careful! 】
Bifang nodded. He was confident but not arrogant, and he was well aware of the danger of this matter.
But that's what adventure is, isn't it?
Discover ancient creatures that have long been extinct.
It’s exciting to think about such an achievement. If the biological discoveries are of great value, they will definitely be recorded in history!
Once this kind of news is released, I'm afraid countless people will be eager to get in and take a look, let alone Bifang himself?
If the live broadcast of Mohe made him well-known in space, then the discovery of mysterious ancient creatures would make him famous in time. How many adventurers can have such an experience? Do you dream of having such an opportunity?
This is a danger as well as an opportunity, containing fame and fortune that can drive people crazy. Bifang does not pursue fame and fortune, but he also enjoys the satisfaction of achieving success.
Last night I was still thinking about how to make up a reason to go in the water and try it out, but today someone came to my rescue!
At the same time, the appearance of this professor brought back many memories for Bifang.
The two had never met before, but from just a few words of communication, Bifang was reminded of the old professor who had always taught him in his previous life.
He also has an obsession with academic research that is difficult for others to understand. He is strict with himself, but very tolerant of his colleagues.
When he came back to the pond, Bifang did not rush into the water, but observed the pond.
There are a lot of preparations that need to be made. The first is the groundwater system. There must be enough oxygen underground, otherwise the dissolved oxygen content in the pond alone would definitely not be enough, which means that the underground space is not small.
The water level in the pond has dropped a lot compared to yesterday. It shouldn’t be due to evaporation. Why?
It is unlikely that there are plants in underground caves, so if it is pitch dark, a torch is very necessary.
At the very least, you should fill your backpack with flower sticks and some flammable plants as much as possible to ensure that you have light in the cave.
No one knows the situation inside the cave, so it's better to be cautious. If you figure this out, your chances of survival will be greatly increased.
Moreover, even if it is a creature that has never appeared before, we can sometimes infer a lot of information from its evolutionary chain and infer its habits. Perhaps you can ask the professor.
Bifang kept searching his brain and finally asked a question.
"Professor Gu, can you tell me about the relationship between Tiktaalik and the coelacanth and lungfish?"
pretty!
Upon hearing this question, Gu Qingyuan almost clapped his hands in admiration. The other party was definitely not just an ordinary retired special forces soldier who was good at wilderness survival!
Even many of his professional students, after understanding the peculiarity of Tiktaalik, were unable to point out this problem in such a short time.
"Is it that exaggerated?" Wu Gang scratched his head, not quite understanding his teacher's excitement.
The speed at which he types is almost as fast as the speed at which he scolds his teammates when playing games.
"I usually tell you to study hard, but now you don't understand anything, right? I dare say that if I were to make a test paper, you would definitely not score as high as this young man!" Gu Qingyuan was very disappointed with his student.
"How is that possible!" Wu Gang was dissatisfied. The other party was very good at identifying animals and plants, but biological evolution was not just about knowing how to identify animals and plants.
"How is it impossible? Forget asking. You can't even see the key point of this question! Don't you find that these two creatures have one thing in common?"
"Uh...are they all lobe-finned fish?" Wu Gang scratched his head, thinking about what his teacher had said about the biological evolutionary relationship, and came to this conclusion.
Sarcopterygii are a superclass of bony fish, most of whose members are now extinct. This type of fish is characterized by the presence of an axial bone in its fins.
This is evidence of biological evolution coming ashore!
"That's right! Throughout the long history of biological evolution, no matter what creatures we see now, near or far, connected or separated, there is always an invisible bridge connecting all life together!"
"And the lobe-finned fish are what closely connect all the vertebrates on land and the fish in the water today! The two fish he just mentioned are the only two lobe-finned fish still alive today!"
Gu Qingyuan not only answered Wu Gang, but also typed these words on the barrage to answer the questions of netizens.
[So awesome? ]
[I checked, the only coelacanth alive now is the lacerta! ]
[Why did I find that it appeared between 200 million and 300 million years ago? How come it is later than that Tik? ]
" That's not how is understood. The movement of organisms onto land is just an evolutionary trend, not a necessity. Otherwise, there wouldn't be so many fish still living in the sea. The two are just confirmations on the evolutionary chain, and different species show different trends in moving onto land."
"And from the perspective of going ashore, Tiktaalik's evolution is indeed superior, because it is both a fish and a quadruped! Compared to the signs of lobe-finned fish, it is direct evidence! It is the missing link of biological evolution!"
Gu Qingyuan briefly answered the netizens' questions and then continued to answer Bifang's questions.
"The 'fins' of this creature had primitive wrist bones and simple toes, suggesting they could bear weight and even bend like fingers."
"From this point of view, the most similar quadruped is the crocodile. The spiracles on the top of the head in the fossils also show that they have lungs that function as well as gills! This is similar to the lungfish!"
At this point, Wu Gang roughly understood why Gu Qingyuan was so excited just now. It turned out that Bifang's question was so sharp.
Directly point out the only two surviving species in the evolutionary chain of creatures coming ashore!
Wow, that’s awesome!
Wu Gang was completely convinced this time. If the teacher hadn't been occupying his seat, he would have wanted to push him away and give the host a few meatballs as a reward.
"So that's why it dared to come out of the water to attack me yesterday?" Bifang touched his chin and figured out many key points.
From the perspective of organisms coming ashore, the other party has evolved, but not completely. The monster can move , but its tail fin prevents it from completely leaving the water environment.
So when Bifang grabbed the monster's tongue and tried to drag it away from the water, the monster struggled so violently that it would not let Bifang let go even at the risk of breaking its tongue.
So if you encounter danger, just go ashore decisively and you will basically be fine. This is very different from crocodiles.
But if you go into the water, the situation will be completely reversed.
Underwater, the opponent is a predator that is much better at swimming than the crocodile!
