For most people, there are only two places where you can see goats . Either it is on the dining table, or it is on the TV, especially the goats on the dining table, which leave people with absolutely beautiful impressions.
But For Newton and Darwin , the existence of goats is definitely provoking their bottom line in . not only almost destroyed the origin of evolution theory , but also completely ignores the laws of physics and walks on flat ground on cliffs.
What exactly did the goat do, and offend two big-name figures in physics and biology ?
offends Darwin
Goat offends Darwin, which is in the Pacific Ocean Cologne Islands . This small island surrounded by the sea is rarely affected by human activities because it is far away from the mainland. The evolution of biological process is more natural and primitive.
Cologne Islands
Darwin came here in
and goat was in
is bad, but it is bad. three goats, two males and one female . In addition, has sufficient food and . has no natural enemy 's living environment. They are like Teddy possessed thriving .
spent more than 130 years . By 1990, the goats on the Cologne Islands had reached 250,000 , almost squeezed the indigenous people without a place to live , especially the Galapagos turtle that lives here.
Because they are herbivorous animals like goats , but goats have sharp hooves as a helper, which can dig out all the grass roots and eat them. Wherever they pass, there is almost no grass growing. The slow-moving elephant tortoise can't compete with them at all, and many of them are starved to death.

plus The reproduction of the tortoise is very difficult to . It can only lay more than a dozen eggs at a time, and it will take more than
Originally, the population of more than 1.2 million , in more than 30 years after the goat landed on the island, cliff-style fell to more than 2,000 , which is only one step away from extinction.
Galapagos turtle population
Of course, the victims are not the only ones. Many species are like turtles. Because of the impact of goat breeding , the population has dropped sharply, and the ecosystem of the Cologne Islands almost collapsed .
In order to ensure the biodiversity here, the local government finally decided to dispatch the army of to directly eliminate the flooded goat population , so as not to rekindle and threaten the ecosystem of the Cologne Islands again.
At the beginning, it was soldiers who went directly to the island and killed when they saw it. However, this guy's running speed was too fast, and he could catch up with four legs. The hunting efficiency of is too low.
The local government simply used armed helicopter , taking advantage of the advantages of altitude and speed to centrally process the flock. took a year to , and cleaned up 90% of the flock .
The remaining 10% have become a flock. Even if is patrolling in an armed helicopter, it is difficult to find the flock of sheep again. Helplessly, the local government can only find another way.
finally chose to send spies to the flock, install the positioning system on the ewes, and then let these spies search for the flock by themselves. After determines the specific location of the flock, will send someone to annihilate it.

After spending a full two years and sending more than 900 spy sheep, the goat flock that flooded the Cologne Islands, finally was completely eliminated in 2006.
However, the goat's strong record did not stop because of this. With its unique geographical environment and the ecological environment without large predators, Australia once again became the victim of the invasion of of species .
The Australian government also took turns to fight helicopters and spy sheep, and it took several years to completely solve the problem of goat invasion.
Qi Live Newton
Under the video of Goat flying over the eaves and walking on the wall , you can often see many netizens leaving messages to joke: " Newton's coffin board cannot be pressed again ." From the perspective of visual effects alone, it does have some meaning of violating the laws of physics, and no wonder netizens joked about Newton.
goat 's rock climbing skills is also the product of long-term evolution. The principle is actually the same as human rock climbing. It is all step on the raised stone and leverages to achieve the effect of climbing upwards.
, however, goat hooves have a relatively small force area, and the front ends of the two fingers of are sharper, which allows them to hold on to the protruding stones on the cliff.

hoof base and cartilage , which can not only help you grasp the stone wall, but also play a certain buffering function , which can make them perform various difficult actions on cliffs.
Of course, some netizens have also opened up their minds. I won’t mention the issue of body structure for the time being. Let’s discuss psychological problems. There are so many goat in the world, and they can basically achieve flying eaves and walls . Isn’t there anyone who suffers from acrophobia ?
If you want to answer this question, you must first understand the eyes of goats . It is different from the round pupils of most animals. All goats have horizontal pupils . The special through-hole structure of
allows their field of view to reach
Plus the eyes and the ground are always in parallel, so that When they look at cliffs, there is no difference between them and flat ground .
In other words, from the perspective of goats, they walk on the flat ground from beginning to end, so there is no problem of fear of heights.
This special pupil structure of is basically considered to be tailored for goats. I just don’t know if friends who suffer from acrophobia will express their envy of this.
