Why did large land animals go extinct 10,000 years ago?

Because 10,000 years ago. The mass extinction of large land animals was also caused by a meteor hitting the Earth 10,000 years ago. Mass extinction of animals. This is also the origin of other land animals.

10,000 years ago, the reason for the large-scale extinction of large land animals is natural disasters.

Because of the changes in the weather on the earth, the weather conditions have changed in various ways, resulting in weather conditions that are not suitable for the growth of large land animals, so that large-scale extinctions have begun.

Because of the sudden and dramatic changes in the weather and climate, most of the animals died out because they could not adapt to it, and it also had something to do with their size.

The reason for the mass extinction of large land life 10,000 years ago was that an asteroid hit the earth at that time, causing the extinction of most life on earth.

As far as I know, it was because of the changes in the earth's crust and the global climate that the big animals that were not able to adapt to the environment became extinct.

Because of the change of the environment, the food decreased, and the food of the large land animals decreased, and they began to become extinct.

Because more than 10,000 years ago, there were large-scale apocalyptic times, such as volcanic eruptions, and some crustal movements.

More than 10,000 years ago, large land animals began to migrate on a large scale because their homes were no longer able to live.

There was a reason why these animals began to go extinct on a large scale, and there must have been some particularly horrific natural and man-made disasters that left these animals with nowhere to escape.

According to this historical record, it seems that the volcano hit the earth and caused the submarine volcano to erupt, which made this large animal extinct.

The living environment changes drastically due to external reasons, resulting in discomfort.

I think the mass extinction of large land animals more than 10,000 years ago was due to the fact that humans began to exist in the world.

I think maybe it's because the earth must have changed a lot at that time, or the environment in which they lived changed a lot.

Caused by the frequent activity of human beings.

The colder the climate, the larger the animal; The hotter the climate, the smaller the size, the more advantageous.

It's just that there are a lot of these land animals, and he probably really makes me feel a little bit better.

The shrublands gradually turned into pure grasslands, which can be studied from the material in their fossilized teeth.

Ancient centipede insectsIt is the earliest known extinct animal.

The ancient centipede insect lived in the Carboniferous period and became extinct about 300 million years ago, and was the first invertebrate to appear on land.

In 2008 Wired

It was selected as one of the top 10 extinct species of antiquity.

Characteristics of the ancient centipede insect

Ancient centipede insects were born up to feet (about a meter) in length, similar in appearance to modern centipedes, and their appearance was very terrifying, and their size was huge. Thankfully, this animal lived more than 300 million years ago and will never suddenly appear to anyone.

Although it is not certain what they were eating, there must have been a lot of nutritious nuts and seeds in the deciduous layer at that time; They can also be predators, invertebrates or even amphibians.

and other small vertebrates for feeding.

What caused the extinction of the species of the previous earth.

Episode 18 What Really Happened 65 Million Years Ago? Scientists have found new evidence of the extinction of the dinosaurs.

What happened to the Earth during the extinction of the dinosaurs 65 million years ago and the emergence of humans millions of years ago.

At present, there are two theories in the scientific community, one is that 65 million years ago, a relatively large asteroid hit the earth, resulting in the extinction of most of the earth's organisms, including dinosaurs, and the second theory is that the earth has undergone violent geological movements, volcanic eruptions, sea and land changes, and fundamental changes in climate, resulting in many organisms unable to adapt and die and extinction.

The mass extinction of the dinosaurs, which is widely believed by the scientific community to be caused by meteorites hitting the earth.

How can there be, it's just that the former may understand and imagine something.

In general, large animals eat a large amount of food and move slowly, so it is not easy to adapt to changes in the environment. Therefore, the so-called survival of the fittest, and the elimination of the unfit is like this.

Food scarcity, climate change, the natural law of survival of the fittest.

Because the larger the animal, the more difficult it is to adapt to the changes in the environment.

With drastic changes in the natural environment, small animals such as dinosaurs need a lot of energy and enough food to survive, and environmental changes have affected the needs of dinosaurs, leading to their mass extinction.

Changes in the size of a species are always due to natural selection, and when it comes to what body type is more suitable for survival, natural selection allows it to evolve in whatever direction.

To put it simply, it is: natural selection, survival of the fittest.

After the extinction of the dinosaurs, did there ever be other large animals on Earth that ruled the earth? The ultimate beneficiaries of the extinction of the dinosaurs were mammals, which, after a long period of evolution, eventually occupied the ecological niche of the dinosaurs. Although the largest mammals in prehistoric times never reached the size of a large dinosaur, overall, they were much more powerful than any living elephant, rhinoceros, or tiger.

Of all the prehistoric giant mammals, Indians are the only ones as big as the giant proboscis tens of millions of years ago, living between 30 million and 16.6 million years ago.

<> it weighs 20 tons and is the ancestor of the modern rhinoceros (which weighs 1 ton). Will there be animals of comparable size after the dinosaurs die out? The answer to a tooth for a tooth is yes, the SP and the Tien Shan Giant Rhinoceros are the most famous of them, the Tien Shan Giant Rhinoceros is by far the largest mammal, used in the Oligocene about 30 million years ago, it reaches a length of 9 meters, an average weight of about 16 tons, and consumes 500 kg of food per day, but it is a vegetarian; It died out due to natural disasters.

After the extinction of the dinosaurs, many large animals appeared, and some of the strength did not belong to the dinosaurs at all, but after all, in the final analysis, because the oxygen content is decreasing, so that the opportunities for large animals to get less and less, and excessive food consumption exceeds the capacity of the food chain, so they can not reproduce and become the overlord of the earth, human beings are the most consistent with the earth's environment, and human success is accidental and inevitable.

Do a detailed explanation of the problem for a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me a lot, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

Nope. Apes appeared, that is, our ancestors, and with the development of technology, they slowly became modern humans.

According to relevant investigations, it is shown that after the extinction of the dinosaurs, there were also blue whales on the earth, and other large animals ruled the earth.

No, after the extinction of the dinosaurs, the next person to rule the earth is our current human being, human beings have thoughts and civilizations.
