Have giants ever existed on Earth? What are the patterns of body size of living things?

So far, I have not heard of the scientist who has found traces of the existence of giants, because the size of living organisms is constantly evolving with the environment, and there is no fixed pattern.

There have never been giants, and the human body structure is also reasonable, a certain height will have a corresponding weight, if it is too tall, it will bring great difficulties to the movement, so there will be no giants.

According to the current discoveries of mankind, there should be no giants on Earth. The size of a creature is affected by its own weight-bearing capacity, and its weight is proportional to the contact area of the ground.

It is said that there is a family of giants, but it has not been officially confirmed, so the data is not very certain, and the body shape of the creatures changes according to the development of genes, so there is no big law at all.

According to the archaeological discoveries of scientists, there may have been a giant race many years ago. They are said to be large ape-like creatures, but no definite pattern of their size has been discovered.

The largest animal in the world is the blue whale, which is not only the largest cetacean, but also larger than the largest dinosaur ever lived on Earth. The blue whale is the largest of all known creatures from ancient times to the present, with a general body length of 2,400 to 3,400 centimeters and a weight of 150,000 to 200,000 kilograms.

The blue whale is the largest and heaviest animal on the planet, belonging to the mammalian family, cetaceans and carps. It is widely distributed and can be found in oceans from the Arctic to the Antarctic. The blue whale has a slender body and a blue-gray back, although it can sometimes be lighter in the water.

At least three subspecies of blue whales are known.

Because the oxygen content in the air is too small to support the survival of giant organisms, in ancient times, there were so many large organisms.

Because human beings are now more adaptable to nature, and because of genetic limitations, they have not evolved giants.

Because the evolution of nature is also regular, evolution will stop to a certain extent, and there will be no unlimited evolution, because the surrounding environment limits the size of human beings.

Are there really giants in the world? In many myths, there are descriptions of giants. They often do it with sticks. Since the myths of various peoples have their figures, then this creature must have existed.

In 1997, when Athens was repairing the subway, the bones of giants were dug up, and the huge human bones shocked the society at that time, which also made many people doubt, could it be that there are really giants on the earth?

All I can say is that there are still many unknowns in this world. Although the scientific evidence currently available to mankind does not support it, my intuition tells me that there is. Because almost all civilizations have legends of giants in their mythology.

It is possible that there were giants in prehistory, or that giants were visitors from outside the sky. In short, giants should not be groundless. On an island in Indonesia, dwarf tribes have been found with DNA components from other races (unlike our Homo sapiens), and the primates should have had more than one subspecies of Homo sapiens.

Non-existent, living things evolved from tiny creatures, and man evolved from fish in the beginning.

No way. Previously, dinosaurs were the largest animals.

Thousands of years of history should have.

<><1, the largest fish --- Leeds.

Leeds fish lived in the oceans during the Jurassic period.

This fish was discovered in the 19th century and was initially mistaken for some kind of giant dinosaur because of its imperfect skeleton and hand.

Today, more than 70 fossilized bones of giant Leeds have been discovered one after another, and their understanding is becoming more and more comprehensive.

They can grow up to 16 meters in length, and there is also a theory that they can grow up to 30 meters or even 35 meters in length, almost surpassing the blue whale, the largest animal today. Leeds fish feed on plankton in the sea and eat in a similar way to blue whales.

2. The largest mammal--- the blue whale.

With a body length of 30 meters and a weight of 180 tons, it is currently the largest known animal on Earth.

Blue whales prefer to swim at depths of up to 18 meters below the surface of the water because this depth removes the drag of surface ripples.

They are extremely capable of diving, allowing them to dive to a depth of 500 meters and stay underwater for 20 minutes because they have a giant lung with a capacity of 5,000 liters.

Blue whales also have a great appetite and need to eat more than 3 tons of food a day, which contains 1.5 million kilocalories of energy, which translates to enough food for a day to feed tens of thousands of people.

3. The largest reptile --- the fragile two-chambered dragon.

Scientists have believed for years that the body of the fragile double-chambered dragon could grow up to 58 meters long!

If this is true, then the blue whale will drop to second place in terms of body length. Unfortunately, no complete fossil of the fragile double-chambered Peilong skeleton has yet been found, and the existing fossil fragments can only be used to speculate about this animal.

It is said that the fragile double-chambered dragon fed on ferns, which took refuge in the forest during the day and only went to the open area at night to eat.

4. The largest invertebrate - the ancient centipede.

Most centipedes are no more than 20 centimeters long, and the largest centipedes today are only about 60 centimeters long. Their ancient ancestors were able to grow to more than 2 meters long.

In the Carboniferous period, 300 million years ago, ancient centipedes could grow to 2-3 meters.

There are two reasons why it has grown so big:

1. At that time, the climate was warm and the oxygen content of the earth was high;

2. There is no predation for large rent-only vertebrates.

Ancient centipedes look scary, but they don't actually have frightening lethality. They are estimated to be a herbivorous animal that feeds on ferns and mushrooms.

Because in the process of development, it is limited by the environment, affected by the environment, and affected by the diet, so it will become smaller and smaller. The scientific explanation is that it has been affected by geological disasters and natural disasters, and in order to better adapt to the environment, it will evolve smaller and smaller.

This is because the oxygen of the earth is now weak, not as much as the oxygen content of the earth before, so it has become very small now.

Because the environment is now very badly damaged, the oxygen content in the air has become less, so the size of living things is very small.
