Live Wilderness Adventure - Chapter 670 evolutionary integrity

Musk ox is an endemic species living in the Arctic tundra.

In summer, it tends to shelter in moist lowlands, such as river valleys and lakesides; in winter it moves to higher hillsides, plateaus, and places where deep snow accumulates for foraging.

Under normal circumstances, musk ox is extraordinarily docile, stop to eat a little food, then lie down on the ground and chew slowly, and soon fall asleep.

When you are a little awake, then walk forward for a while, and then repeat the old trick, eating food, ruminating, and dozing off.

It seems to be lazy, but it contains the survival wisdom of polar creatures.

This reduces energy consumption and reduces food requirements.

Since the musk ox is extremely efficient at maintaining energy, it needs only 1/6 of the food required by an ox of the same size.

That's why Bi Fang can rest assured to wait for a day to track.

Under the condition of natural walking, even on foot, he is confident that he can catch up with the musk ox.

Coupled with the strong smell on the grass, it proved that the musk oxen did not leave for a long time, definitely not more than five days.

Of course, walking slowly does not mean that the musk ox can't run fast. During the breeding period, these super beasts weighing more than 350 kilograms can run at a speed of nearly 50 kilometers per hour.

Under the terrifying mass and speed, it brings an extremely huge momentum. These furry arctic behemoths collide head-on and stab their opponents with huge sharp horns. The moment they collide, the ground trembles.

What's more, a male musk ox may be hit on the head more than 2,100 times during their 10- to 12-year life cycle.

The audience almost jumped out of their seats when they heard this terrifying number of times.

【2100 times? ? ? 】

【Momentum of 5,000...】

[Have you calculated how many joules the kinetic energy is by hanging a large one? 】

[After a calculation, the momentum of 5,000 is roughly 35,000 joules of kinetic energy. . . 】

[The kinetic energy of an AK47's muzzle is about 2,000 joules (covering your face)]

[Is it the same as getting hit by an anti-aircraft gun? 】

How did musk oxen survive these attacks without their brains being smashed into mush?

This is a question that lingers in everyone's mind.

It is like seeing the giant bull that created the mountain in myth and legend.

"It's always been thought that animals that attack with their heads like musk ox and bighorn sheep are somehow immune to head damage. It's like they have magic horns."

"But in fact, this kind of impact is indeed damaging. Not only is it not immune, it will also cause chronic damage to the brain of the musk ox, just like our human Alzheimer's."

Bi Fang's statement has scientific basis, and the behavior of musk ox is also the first time for humans to detect whether this collision of animals will cause damage.

"In the brains of living things, there is a protein called TAU, whether due to aging, genetic problems or mechanical influences, as long as neurons are damaged, they are torn apart, and the tau protein breaks down and forms clumps."

"When probed by fluorescent labeling, the shiny tau protein in the musk ox's brain resembles a lit Christmas tree."

"Evolution can lead an individual species to a surprising path of self-destruction."

Bi Fang told a shocking fact.

All evolution is essentially for the better reproduction of species.

The survival of the individual is actually irrelevant.

This is also the most cruel scene in evolution.

As for whether the musk ox really suffers from dementia or something, who knows?

Musk oxen don't have behavioral scales, and humans don't know if they feel forgetful.

There is only one thing, no doubt, that their brains are traumatized.

"Musk oxen have many fights every year, but if they want to successfully reproduce even once, they have to collide and catalyze the slow death of the brain. From an evolutionary point of view, as long as the musk ox 'doesn't die'."

audience:"???"

"For example, the shrew is a small carnivore native to mainland Australia and Tasmania. They have a characteristic that they are 'life-long babies'."

"It's about breeding once and then dying. Female shrew can live two to three years or more. Males rarely live beyond 11 months."

"They have a really crazy mating season, the male's breeding season can last 12 to 14 hours, after which each male copulates with as many other females as possible - leading to his death. ."

"It's a bit like a hive, where the worker bees don't reproduce themselves to successfully acquire genes, but help their mother, the queen of the colony, reproduce offspring."

"An ant colony or beehive is more of a large animal, with the queen or queen bee representing the reproductive organs. These little worker bees are numerous and require only a few resources to raise, so they are somewhat similar to human cells."

"So, the musk ox is actually the same. As long as it can promote reproduction, the survival of that individual is actually irrelevant compared to the entire population."

"It also results in male musk oxen living less than 15 years, while female musk ox can live 15 to 23 years."

"Their lives are not that complicated. So, they may only live until they have done what they need to do."

The brand-new snowshoes are made of wooden boards. Compared with the original simple twig version, the effect is at least several times better. When you step on the snow, it stops after only a few centimeters, reducing the resistance to a minimum.

Bi Xiang was heading into the distance, but the audience was still caught in the "brutal truth" just now and couldn't extricate themselves.

[Does humans have such individual reproductive defects? 】

There are audience questions.

"It's not clear yet~www.novelbuddy.com~ Bi Fang shook his head, this is his blind spot of knowledge, or no one has ever studied this area, but there is no doubt that there are.

But I can't go into details. Bi Fang is afraid that the live broadcast room will be blocked, cough.

Although the probability is small, it is better to say less.

[I was hurt by wine, so haggard! Stop drinking alcohol today! 】

[Shi, you didn't mention a word]

【Can't be astringent】

[The emperor is on top, I am inseparable from gambling and drugs! 】

After chasing for a whole day, Bi Fang did not gain anything. Looking at the sun that was about to set, Bi Fang sat on the ground.

Compared to the time when I first came here, I was able to maintain more than six hours during the day, but now I am not satisfied with even six hours. The time is terribly tight.

But it was too early. Bi Fang only thought for a moment before making the decision to travel overnight.

It was a sunny day for two consecutive days, and the night was not unbearably cold, so it would be a pity not to take advantage of it.

After chasing for a day, the biggest good news is that there are finally visible musk ox traces on the snow layer, which means that the distance between Bi Fang and musk ox is only two days after the end of the snowstorm.

Bi Fang is sure to catch up with them tomorrow morning.
