Life in the ocean gradually came to land and became amphibians, and after they adapted to life on land, they gradually evolved into beasts running on land; Creatures on land continue to evolve wings that can help them soar under the blue sky and white clouds.
There is a creature in nature that can eat lions for a living, and after the wings are spread, it is more than 7 meters long, the body is more than 2, and so far no natural enemies have been found, which is the world's giant eagle - the Argentine giant eagle.
Most of the birds and animals that soar in the sky are small and lightweight, so they can borrow the circulation speed of air to soar in the sky, but the Argentine giant eagle is huge, it is also a prehistoric giant beast, it can even eat the king of the forest, the lion, in its eyes everything is food.
The argentine giant eagle with its large size and amazing ability to hunt and kill has no natural enemies, and their wings can reach a maximum length of seven meters and weigh about seventy kilograms, and we imagine that the Argentine giant eagle soars in the sky, like a small fighter, extremely handsome.
But scientists can't imagine how such a large Argentine eagle could soar through the sky. Later, scientists discovered the fossil of the Argentine giant eagle and found the secret of its ability to soar under the sky.
The Argentine eagle does not fly by stirring its wings to obtain a huge air current, it pushes itself through the winds of the Andes and the upward currents in the air, and it is not so much that the Argentine eagle is flying as it is glidering.
Due to the special skull shape of the Argentine giant eagle, it can also swallow the prey in one bite, but the Argentine giant eagle is not without shortcomings, to withstand the force of the huge body flying in the air, so the gliding bone of the Argentine giant eagle is very fragile, and its bone wall is extremely thin.
Although argentine eagles have amazing hunting ability, they prefer to be a "salted fish" in most cases and prefer to eat the carrion of animals on the grasslands.
The giant Argentine eagle has no natural enemies, but why is it able to go extinct? The huge size is both its advantage and its disadvantage, which is called success and Xiao He, and defeat is also Xiao He.
The Argentine giant eagle can even eat lions with its oversized size, but due to its lack of natural enemies, its reproduction rate is very slow, and the Argentine giant eagle can only lay one or two eggs a year.
It takes about ten years to go from juvenile to full sexual maturity, so such lazy evolution and development led to the Argentine giant eagle eventually being eliminated by the laws of nature, of course, the argentine giant eagle lifespan is very long, its life span is about 50 years to 100 years.
Because the Argentine eagle does not have the ability to directly instigate wings to take off, and its take-off is to use the air rising air flow to glide, so it needs to live its nest on the cliff face.
The cubs of the Argentine giant eagle are also hatched under such conditions, so it also causes the cubs to die because they accidentally fall off the cliff, thus reducing the overall number of Argentine giant eagles.
Although the Argentine eagle has perished, there is still the blood of the Argentine eagle near the Andes Mountains, which is the modern version, the giant eagle - the Andean condor.
In terms of body size, it naturally cannot compete with the Argentine giant eagle, but it is also a huge eagle today, with a body length of about one point and three meters and a weight of more than ten kilograms.
The habitat of the Andean condor is similar to that of the Argentine giant eagle, they like to nest on the cliffs and cliffs, and the flight principle is the same, because of their large size, they can only glide through the air current, and the Andean condor reproduces at the same speed as the Argentine giant eagle, and they are willing to eat the carcasses of the steppe animals.
To sum up, due to the high degree of similarity in life habits, it is also directly determined that the Andean condor is the descendant of the Argentine giant eagle, but they have made their body smaller in the process of evolution.
But the current survival status of the Andean condor is still not optimistic, when the Argentine giant eagle was because they could not adapt to the laws of nature, and was eliminated by the laws of nature, but the impact on the number of Andean condors is the hunting behavior of humans, because humans hunted and killed the Andean condors, so the number of Andean condors is very rare.
