"Anyway, it's not too surprising." Lu Wu squatted on the ground and observed the restless wolves in the cage, he pulled Pu Luo to squat down together, pointed out the abnormalities of these wolves to him one by one, and explained: "There is no reproductive isolation between wolves and dogs, their habitat is too close to human society, and the dogs in the countryside are basically free-range, so the appearance of mixed breeds is unavoidable." ”

"In fact, not only wolves, but most animals now have the problem of genetic contamination, cats have the influence of domestic cats, aquariums have the impact of wild release and farm escape, and even wild boars cannot avoid being affected by domestic pigs."

Pu Luo was stunned for a moment, and tilted his head: "Isn't it good?" ”

Lu Wu was stunned for a moment, raised his eyes to look at him, and when he met the young man's dark eyes, he suddenly smiled: "It's not good, when humans breed animals, they will choose to focus on cultivating the parts they need." ”

"Dachshunds, for example, were slightly slender in the early days just because they wanted to catch wild animals in the holes, but because humans liked their special shape, their vertebrae were extended to the point they are today in less than two centuries."

"The special body shape and deformity of the hobby make the sausage lose the qualification of happy jumping in this life, and at the same time bring the risk of spinal displacement and obesity." Lu Wu shook his head, his eyes full of compassion and something indescribable.

His eyes fell on the wolves in the cage and said, "Of course, it also makes their ability to survive in the wild almost zero, and if such genes are inherited to wild dogs, or even if they affect wolves, it will be a real disaster." ”

"But in the wild, the female dog won't agree to her breeding request at all." Pu Luo glanced at him with some doubts, he thought for a while and said: "I have a different perspective from you Oh, first of all, animal reproduction in the wild is a two-way selection process, and the matching between animals and animals is very simple and straightforward, that is, the strong are respected." ”

"Whether male or female, they will try to choose the stronger one in their group, and even if anyone in the process has a bad eye and chooses the wrong partner, then the harsh and high mortality of the breeding process will tell them that the answer is wrong. Even if they are lucky enough to give birth to their cubs safely, the cubs that have inherited inferior genes will be screened out by nature and their parents and families and eliminated. ”

"Even if any lucky person can grow up and become an adult in such a rigorous investigation, and then enter the □□ stage and then mate with another person of the opposite sex, and then breed, raise cubs, reach adulthood, and find a mate, and so on from generation to generation, then it can only show one thing -- this inferior gene is not inferior, on the contrary, its appearance must conform to this ecological environment."

"Of course, this is all without human intervention, and for animals, does it really matter whether the pedigree, the genetic purity, whether it is purebred, or not?"

Pu Luo was a little tired from squatting, he changed his posture and missed Lu Wu's somewhat complicated gaze for a moment.

"Breed, bloodline, that's just the way humans define animals, animals don't care about it at all, they just follow their instincts, they look for the strong in the collective, they rob each other's genes for their offspring, so that they can pass on their genes, in the words of you humans: existence is reasonable?"

Lu Wu was silent for a moment, and then he exhaled: "You are right, but the current situation is that all genetic contamination is caused by human error, and if we don't work hard to do something, we ......."

"How do human beings know what kind of genes are 100% perfect?" Pu Luo hooked his lips slightly: "Even human beings themselves have evolved to be more suitable for the local environment after countless attempts, aren't they?" ”

"In order to adapt to ultraviolet rays in different places, human beings have different colors of skin, different sunlight intensity makes the color of the pupils different, and the length of the eyelashes is determined by the need for facial contours and protection against wind and sand.

"No, even human beings themselves have paid in the evolutionary game of biology to make the gestation period increase, make the mother prone to dystocia, prolong the adult period, reproduce the ability, and force the father to participate in the process of reproduction and nurturing, even if it affects the strength of the limbs, even if it puts great pressure on the pelvis, it will open the door of wisdom."

Pu Luo put one hand on his cheek and looked at Lu Wu with a clear, bright, and somewhat sad look: "My life span is quite long...... So I saw a lot of [precedents] ......."

"Then please ask Mr. Xiaopu to help me see the future in many years."

Pu Luo was stunned for a moment, as if he didn't expect to hear this answer.

"I and my colleagues didn't choose to do it because it made sense."

Lu Wu suddenly sneered, and a young man with a flamboyant eyebrow was reflected in Pu Luo's slightly dilated pupils: "No one knows whether it makes sense to do this until they reach that fateful moment. We do it only because we want to do it, and because we feel that 'they' that will be cruelly eliminated by nature may care. ”

"Of course, it's also possible that I'll become a biological sinner and just delay the evolution of living things by hundreds or even thousands of years, and if that is the case, don't tell me.

Pu Luo opened his mouth, but he didn't know what to say for a while.

Lu Wu, like him, held his chin and looked at the wolves who were annoyed by them in the cage and began to circle in circles, he smiled: "Human characteristics: do not hit the south wall and do not look back, Qilu characteristics: a body of backbone, I can only ask Teacher Xiaopu to be more considerate." ”

Chapter 80

In February, the earth is still wrapped in winter, but in places where people can't see it, there are already many lives preparing for the arrival of spring. The main representative is the Eurasian red squirrel, which is still hibernating, and these little ones start to act early to prepare for the breeding season, while the same kind of chipmunks are still hibernating.

A squirrel named Xiaohong is part of this group of "advance troops".

It waved goodbye to its barely accorded friends in the cold, got out of the hole in the tree, took a deep breath, and then let out a small sneeze.

Although February is already the tail of winter, but this year's winter is so cold that the chill has not faded yet, if it is a young mouse, they will most likely choose to hibernate a little more, but Xiaohong is already a mature mouse with a year of winter experience, so it clearly knows that now is the best time to get out of the nest.

Under the shortage of food, most of the animals have changed their diet flexibly in order to survive, and the fruits and seeds that the Eurasian red squirrels love on a daily basis have basically been emptied after such an operation, and the birds have not yet begun to breed, and naturally there are no eggs to eat.

If it is a young and inexperienced little squirrel, it will definitely look around at a loss and continue to live by eating and saving food, but Xiaohong is different.

It found a good spot last year.

Running along the cascading mountains, hiding in a cave when you are tired, and repeating this six times is its destination.

That place...... It's very strange, there's a lot of food, and there's a lot of predators, but it's all raised by humans.

The quick-witted little squirrels know that the beasts in the iron cage will not hurt them, but can rely on their dexterity and the protection of the iron cage to rob them of their food.

But the reason why they didn't live in it was because the place was refusing to approach them, except in the middle of winter, when the food was withering.

Last year, Xiaohong, under the leadership of her fiancé, spent what should have been a very difficult winter and spring here, but when they were ready to stay here as nests and cubs, they felt the rejection of the land.

Little Red They are not untouched and cheeky, but ...... Hey, something terrible happened anyway.

Thinking of last year's experience, Xiaohong couldn't help but shiver.

But it can't be helped, this year's winter is particularly difficult, so difficult that the red squirrels who are usually lone rangers also have to huddle together to keep warm, Xiaohong has just turned around, and it feels that if it doesn't risk going again, then it may not be able to adjust itself to the best state before the breeding season arrives this year.

But I don't know if it's an illusion, how do you feel, "that place" is a little farther away than last year's memory?

Panting little red drilled into a tree that had not yet grown leaves, and it touched the trunk and quickly recognized it as a peach tree.

It's just that the peach trees in this season are still in the gestation stage, and there are no flowers and no young leaves, but it doesn't matter, Xiaohong decided to write down this place, and in a dozen days and nights, there will be sweet petals to eat.

It ran a few more steps, and then it came across another plum tree, and a few more steps, it was a cherry tree, and it ran again......

What, what's going on? When did there be so many fruit trees here? Wouldn't you be able to eat here this summer?

However, no matter how good the fruit forest is, it is also a matter of the future, and it is imperative that we live until that time.

After resting, Xiaohong began to run again, and this time after repeating two breaks, she finally found her purpose.

It stood up, sniffed with its nose, sniffed again, looked left and right, and did not feel the other party's dissatisfaction, and then walked happily with small steps.

Yes! Sweet tree sap and delicious fruit, here I come!

"Hey, it seems like there's a lot of squirrels in the garden lately."

As soon as Pu Luo looked up, he saw squirrels tossing and jumping among the trees.

To be honest, the color of the fur of these guys is quite similar to that of the trunk of the tree, and the movement is very fast, if it were not for the fact that most of the trees are still bare, it is really not easy to spot.

But seeing this group of guys, Pu Luoke was not happy at all.

No, don't get me wrong, it's not rats and rats, it's just that Pu Luo is simply annoying this group of robbers.

Squirrel...... In particular, the status of the Eurasian red squirrel in the ecological chain is actually similar to that of the house mouse.

Whether it is a hoarding habit or a special ability to give birth, including food and face shape, they are all quacked.

The only difference is probably that the squirrel has a big furry tail, which makes it a little cuter.

"Oops." Pu Luo looked at the squirrel who was holding the fruit of the Acer truncatum and gnawed it, and after eating the fruit and went to drink the sap, his expression was very serious: "If these guys are here, our fruit trees will be in trouble." ”

Xiao Lu, who was holding the camera to take pictures, was stunned, she tilted her head and thought about the eating habits of squirrels, and her expression became serious.

Wild animals are generally not territorial, of course, the territoriality here refers to different creatures, and they still have a sense of territoriality with each other.

Because it is impossible to identify the territory of other animals, the farmlands, fruit groves, and fish ponds planted by humans are excellent hunting grounds for animals, and they not only do not feel that they are stealing, but on the contrary, they will call their friends to come and eat white food.

In fact, if you eat it, you can eat it, and farmers can't afford to lose a little, but the key wildlife has the same problem as people - once there is too much food, it starts to be wasted.

Strawberries are the best only when they are pointed, the sweetest where the fruit joins the stems, and the grapes ripen at different speeds.

No matter how big-hearted and kind-hearted the peasant uncle was, he could not calmly forgive the animals when he woke up and saw the fruits of his labor.

No, Pu Luo was already anxious at the thought that in a few months the fruit grove would be full of fruit that would be discarded after eating a bite or two.

"Don't worry, they're here to eat the sap of the maple truncat, and they'll leave when spring begins." As the only "old man" in Daishan Zoo, Lu Wu's words were very convincing, and everyone's eyes as they watched the little squirrel run and ran immediately became a lot softer.

But then everyone began to study why the Daishan Zoo, which has food, drink and shelter, can't keep the baby squirrels, is there something wrong with their ecology here, or is the squirrel's love for pine trees really strong enough to resist the temptation of fruits?

Several animal breeders were very interested in this topic and were ready to study squirrels as an amateur recreation, and their "non-business" was also supported by the director, and Lu Wu even agreed to let them serialize the "squirrel tracking" on the official account of Daishan Zoo, leaving Pu Luo speechless.

Because、The staff of Daishan Zoo、It's really busy right now!

Spring is the season of recovery, and it is also the season when all kinds of viruses and bacteria begin to wreak havoc, so it is necessary to prepare animals for epidemic prevention before the arrival of spring.

Those who should be vaccinated should be vaccinated, those who should be dewormed should be dewormed, and the cages and food basins where animals live should also be disinfected.

These are still only for the animals themselves, and when the spring flowers bloom in April, the zoo will also carry out a comprehensive disinfection, that is, the area where visitors are located and the woodland will be covered.

At this time last year, the director of the park was still contracted by the director alone, but now the Daishan Zoo has tripled the accessible area of the park, the number of animals has gone straight to the triple digits, and even the tourist rest center has increased by two new Daishan Zoo!

The director alone is already too busy!

In fact, Daishan Zoo has already posted a new job search on the job site, and in addition to the keeper position, they are also hiring a full-time general clerk for cleaning, a full-time repairman for cage repairs and carpentry, and a full-time vendor and security guard.

The reason why full-time is emphasized is that these jobs in Daishan Zoo were all part-time before, and now, the workload of part-time can no longer meet the operation of the zoo.

In addition, according to the current situation, at most half a year, they may have to find full-time financial staff and new media editors, the current part-time staff of these two positions have said that the workload is a little tight, but because the zoo's funds have not been replenished, so the director can only ask them to support a little more.

And the reason why the zoo is in financial crisis again......

Pu Luo slowly turned his head and looked at the western and northern areas of the zoo's ping-pong construction, as well as the infield animals in a state of quarantine readiness, and he couldn't help but show a kidney-deficient smile.

It was also in this winter that Pu Luo really knew how large the land area of Daishan Zoo was, and in that era when land was very cheap, the old director waved his hand and directly contracted more than 2,000 acres of land, and then most of these lands were subcontracted out by him, but there were nearly 1,000 acres of land that could be used to provide the zoo for development, and before, the area of Daishan Zoo was less than one-tenth of these developable areas.

One of the reasons why it was not developed before was that the director had no money, and the other was that the terrain of Daishan Zoo was mainly biased towards the mountains, and there was not much flat land, so it was difficult to expand the zoo.

But now it is different, the country has been engaged in the development of mountains for so many years, and has long invented many corresponding construction and excavation equipment, and the advent of many new building materials has also escorted the walking and climbing in the mountain and forest areas.

As long as the money is in place, there is nothing that cannot be developed.

The operating income of the zoo for most of last year and the income of this year's Spring Festival stalls were all invested by the director to open the mountain and split the stones to build the road, and the stones pulled down were not wasted, and all were used by the director to build a new park.

The new park is a large-scale bovid comprehensive exhibition area, which includes several subfamilies of antelope and sheep in addition to the common genus Bovine.

This exhibition area seems to be very boring, after all, everyone has been accustomed to seeing cows and sheep, many young people have ridden sheep when they were young, but what the director wants to show you is a different bovid.

- They are strong.

In order to reflect this, the director specially set up a person and a cow can look at each other, where humans can feel what kind of behemoth a one-ton cow is

- They are dexterous.

The new park is made of gravel to build a vertical Gobi Desert, where both antelopes and sheep can show humans their extreme climbing skills.

- They are extremely fast.

The circular shape and the wide area of the park provide space for the pronghorn to run at full strength.

- They are extremely capable of jumping.

"Well, that's a bit hard to show." After thinking about it for a while, Lu Wu created a stream with a water width of three meters in the new park, which provided drinking water and perhaps allowed the animals running high to show their jumping ability.

After all, just like humans, the first reaction of animals when they see a pond when they run fast is to step over it instead of stepping on it.

"At its limit, antelopes can jump over a four-meter ravine, and three meters should be no problem in normal times." Pu Luo gave him an idea: "Shall we set up another space where visitors can enter the exhibition area and let them experience it up close?" ”
