Chapter 863 King of Speed
Bifang used two parallel sticks to take the ostrich eggs out of the fire pit intact.
The pure white eggshell was slightly blackened by the flames, but it could be wiped with sand and become brand new again.
Pour cold water on it to cool it down a little, then Bifang pried the eggshell open with a stone and used his fingers to peel it open bit by bit.
"Unlike mammals, which have a short breeding season, birds and their egg-laying season extends almost from spring to autumn. During this period, it is not surprising to eat any kind of eggs."
"Poultry raised by humans, for example, can lay eggs almost all year round."
[ Will ostrich eggs explode if they are roasted directly over fire? ]
【Why did it explode?】
[Anyway, you can’t put eggs in the microwave. I was once blown up by it, and the whole microwave was full of broken eggs. Then I got scolded by my mom. I have a very clear memory of it.]
"Don't worry, it's unlikely."
Bifang's fingers were holding sand and he was obviously burned.
"A microwave oven cannot heat an egg directly because it converts electricity into microwaves, which generate heat in the food, heating it from the inside out."
"The heat generated by the egg itself hits the sealed eggshell, and as the heat increases, it cannot be released, causing an explosion."
"Roasting, on the other hand, heats food through heat conduction, from the outside to the inside, so the possibility of explosion is much smaller. Even if it explodes, it usually cracks, not explodes. That's why many people use the oven to make eggs, such as salt-baked eggs."
"Of course, I just wanted to make things easier, so I threw the eggs directly into the fire pit, like roasting sweet potatoes. For safety reasons, you should not follow my example."
After pouring some cold water, the temperature of the eggshell finally dropped a little. Hot air flowed out along the hole knocked open by the stone, showing the amazing heat contained in it.
The ostrich shell is very thick and hot, so it is difficult for Bifang to peel it.
Harley next to him stood up and paced back and forth, licking his lips, eager to try.
When the eggshell was completely peeled off, the delicate milky white egg white was revealed in front of everyone, emitting slight steam in the air.
"This is yours."
Bifang cut off two-thirds of it with a knife, then cut it into small pieces to quickly cool it down, put it in a large eggshell, and handed it to Harley.
Harley, who had been hungry for almost two days, lowered his head and sniffed. After confirming that there was no peculiar smell, he licked the food happily.
Bifang picked up a piece of trembling egg white with a knife and put it into his mouth, then tasted it briefly.
[How is it? Is it delicious? ]
【What does it taste like】
[I heard it's not tasty? It seems like the bigger the egg, the worse it tastes? ]
[Nonsense, I think the bigger the egg, the better it tastes. Goose eggs are much tastier than chicken eggs.]
[Ah, I feel that goose eggs taste fishy and have a rough texture]
[I feel like goose eggs have a very delicate texture... the yolk doesn't even make you choke, and they taste really good with some soy sauce]
[Let’s have a fight]
"It tastes good." Bifang saw the comments and expressed his feelings.
"I think goose eggs are more delicate than eggs in terms of taste, and the yolk is not so dry. They are delicious. However, as the comments say, some people think goose eggs are not delicious, while others think they are delicious. I have a good impression of goose eggs. I don't know why this is the case. Maybe it depends on the individual?"
"From a scientific point of view, ostrich eggs are the best of all eggs and are called the 'king of eggs'. On the one hand, they are the largest eggs. On the other hand, the protein, calcium and iron content of ostrich eggs are higher than other eggs. Nutritionists call ostrich eggs 'soft gold' and the first choice for 'food supplements' to strengthen the body and improve immunity."
After a few simple words, Bifang and Harley immersed themselves in eating.
The food quickly enters the stomach and reacts violently with the stomach acid that has been waiting for a long time.
The intense feeling of hunger quickly faded from his mind, lifting his spirits and making him feel a lot more relaxed.
An ostrich egg weighs three pounds. Although the eggshell is thick, compared with its own weight, the proportion is not very good. One egg is enough for Bifang and Harley to have a meal.
[It’s a pity that I didn’t get to eat meat]
[How long can you eat such a big ostrich? 】
[To be honest, rolling on the ground at the beginning was a bit stupid (eating melon)]
[Why is the cheetah faster but still can't catch up?]
"In fact, the cheetah's speed is not as fast as imagined. Many sources say that the cheetah's speed is 110 kilometers per hour, or even 120 kilometers per hour, but this is not accurate."
Bifang bit the egg yolk, swallowed it and continued.
"This data did not appear until 1957."
"At that time, the cheetah was already known as the 'king of speed'. It was a global consensus, but no one had ever measured the specific speed of a cheetah running."
"Then in 1957, a photographer named Kurt Severin designed an experiment to test the cheetah's speed."
"He placed a modified bicycle upside down on the ground. A very strong and long fishing line was connected to the wheel of the bicycle, and a bag of meat was tied tightly to the end of the fishing line."
"When people turn the wheel, the wheel drives the meat bag to move, and the cheetah will rush forward following the meat bag."
[Oh my god, why do I feel like I'm seeing a donkey or a carrot (dog head)]
[This is too simple]
[Can the measurement be accurate? ]
[I feel like these things aren't quite accurate. After all, if an animal is hungry, then its state is definitely not online. If it's not hungry, why would it go all out to chase the meat bag?]
[Fuck, that makes sense, but then there is no way to test it, right?]
"Then the test began. As soon as the starting gun sounded, people started to turn the wheel with all their strength. At that time, the speed of turning the wheel almost reached the limit. Then the cheetah started chasing the meat bag, and the stopwatch started timing at the same time."
"At the end of the intense test, the average speed of the cheetah was calculated to be 71 miles per hour, which is about 110 kilometers per hour."
"The test results were later published in the newspaper, and people all over the world knew that the cheetah's speed reached 110 kilometers per hour."
"Even during the process of spreading the rumor, some people even said the cheetah's top speed was 120 kilometers per hour. This is the truth behind the rumored 120 kilometers per hour speed."
Bifang did not finish his share of ostrich eggs. Although he felt a little unsatisfied, he still left some and slowly fed them to Jerry.
Jerry took the egg white with both hands, stuffed his mouth full, and chewed non-stop.
Harley, who was standing next to him, pushed two intact bird eggs over and tried to push them into the fire pit with his claws, but was unfortunately stopped by an outstretched foot.
Eating without restraint is essentially a waste of food.
Bifang would not do that. He put the two eggs back into his backpack and continued explaining to the audience.
"With the development of science and technology and the in-depth study of cheetahs, some scientists began to doubt whether the cheetah's speed is as high as the legend says."
"Plus, the test tools in 1957 were relatively simple, including wheels, stopwatches, starting guns, etc., so the error might be large. So scientists planned to use a more scientific and accurate method to measure the speed of cheetahs."
"In the 21st century, researchers from China equipped 367 cheetahs with the most advanced GPS positioning system."
"After hundreds of tests of cheetahs hunting, people found that the cheetah's top speed was only 93 kilometers per hour - far lower than the 110 kilometers or 120 kilometers that people had originally said."
"Please note that this is the highest value, which was obtained after nearly 400 cheetahs ran thousands of times. It is not the average value or median value."
"And the speed of an ostrich is over 70, so the difference between the two is not that big. Add to that the difference in endurance, and the cheetah won't be able to keep up with the ostrich as long as it makes a few sharp turns."
"That's why I keep emphasizing the necessity of ambushes. Cheetahs are fast and are top-notch fighters in nature, but other animals are not bad either. They are all top-notch fighters. If you're not careful, you might fail."
"After all, the entire natural world is co-evolving, and the speeds of both sides are basically growing synchronously, just like an arms race."
【Coevolution: refers to the evolution of two or more species in a natural habitat. Due to their close ecological connection, their evolutionary processes are interdependent. When one species evolves, the selection pressure between species changes, and other species will undergo evolutionary events that adapt to it, resulting in a phenomenon of high adaptation between species.】
"That's what this netizen said. This is co-evolution. There's a famous hypothesis called the Red Queen Hypothesis, which was proposed by evolutionary biologist Van Valen of the University of Chicago in the United States in 1973."
“It is believed that there is co-evolution between different species.”
"For example, if a cheetah has a genetic mutation that causes it to run faster, then the antelope it preys on will also run faster."
"Because, due to genetic reasons, slow-running antelopes will be eaten by cheetahs, and the genes of these antelopes cannot be passed on to their offspring. In other words, the genes for running slowly will be eliminated by natural selection, which will cause the antelopes to run faster and faster."
"Similarly, when the antelopes run faster, it will be more difficult for the slower cheetahs to catch them and they will have a greater chance of starving to death. Therefore, the evolution of the antelopes will also select the genes of the cheetahs, making them run faster and faster."
[Shit, so that’s how it is]
[I always thought that the cheetah's speed was over 100]
[Not necessarily. After all, there are Bolts among humans, right? ]
"That's right." Bifang smiled. "Just like what the netizen said just now, if you're hungry you can't run, and if you're not hungry you don't want to run. You can know the average speed, but it's hard to measure the maximum speed of animals. They don't have sports competitions like us humans."
"So, maybe there really is a cheetah that can run at a speed of 100 kilometers per hour."
"But despite this, the cheetah remains the fastest cat and the fastest animal on land."
"The reason why the cheetah can run so fast is related to its streamlined body, long tail, strong heart and lungs, and light bones."
"Come and listen to Harley's heartbeat."
Bifang called the drone, and it immediately flew to his side and approached Harley at the same time.
Halley was very curious about the big black bird-like thing, so he stretched out his hand and tried to take a picture of it, but unfortunately he was held down by Bifang. While it was unable to move, the audience could hear its strong heartbeat.
"Pay attention to the cheetah's exhalation and inhalation, and then pay attention to its heartbeat."
[Emm, what happened? ]
【I didn’t hear anything】
【Let me tell you something】
[If you say so, I can't keep a low profile anymore. It's actually very simple. You'll know if you listen carefully. Do you understand? ]
【You are standing here and there? 】
【Drag him out and kill him! 】
"Hahaha, my hint is already quite obvious. Listen, when a cheetah inhales, its heartbeat speeds up, but when it exhales, its heartbeat slows down."
"If it were a human, it would be respiratory sinus arrhythmia, a minor irregular heartbeat, but in cheetahs it's normal."
"This is because the cheetah 's body needs a lot of energy to accelerate in order to adapt to high-speed running. The heart rate increases when inhaling to promote the supply of oxygen to the muscles for high energy, and the heart rate decreases when exhaling to allow carbon dioxide to be discharged at a normal rate."
【Awesome】
[It’s over. Why do I feel like I have this problem too?]
[I saw something wrong after watching the live broadcast (heartbroken)]
What happens if I have an irregular heartbeat?
"Don't worry, it's nothing serious. Sinus arrhythmia itself has no effect on the body. It is just a clinical manifestation. Normal people also have it, especially when they are tired, drinking alcohol, drinking coffee, or suffering from insomnia. Just get more rest and you will be fine."
【Thank you, Dr. Fang】
[After listening to Dr. Fang’s advice, my legs and waist no longer feel sore, and I can climb to the eighth floor in one breath]
You know how to rhyme
【skrskr】
After a simple lunch, Bifang replenished his water resources and continued on his journey with Harley.
As the geographical location moves further and further north, the vegetation on the surface gradually becomes more sparse, and many places even change from the original hard land to sand.
"I don't know how many days it will take for the wet season to arrive, it should be these few days."
Looking at the dry land around him, Bifang felt that all the water in his body was being lost, as if it was being sucked away by the earth beneath his feet.
The temperature is obviously not high, but I have this illusion.
At the same time, a small plant on the ground also attracted his attention.
"Yesterday I showed you how to track animals to find water. In fact, normally, the roots and stems of many plants can also meet our needs. Look at this."
Bifang squatted down and picked up the plant that looked like a tree root.
It was a thing that looked like a root, and it didn't have many branches. It was doubtful whether it was more than ten centimeters tall.
It really takes inconspicuousness to the extreme. Normal people wouldn't even take a second look at it.
But Bifang recognized it at the first sight.
Harley behind him took this opportunity to lie on the ground and rest.
【What is this】
[Can replenish water, cactus (sure)]
"Hey, you guessed it right. This is a cactus."
Bifang took out a dagger and inserted it directly into the soil, digging up the hard earth pit, and then dug up the soil.
"This is a cactus plant called Odia. It's not a cactus in the traditional sense, but its roots are very large. When they are hungry and thirsty, many native Africans will look for this plant to quench their thirst."
"But it's hard to find. You can see how inconspicuous it is when you look at it. It looks just like a normal tree root."
