In the long process of evolution, the solar system has given birth to life, and at the same time, it has also continuously eliminated some that cannot adapt.
Species of the solar system's environment changes. To this day, mankind has not determined the rest of the solar system except the Earth.
Whether life also exists on the stars.
The extinction of the dinosaurs is indeed a natural mystery of great interest to mankind. This is because dinosaurs were once on Earth.
Their extinction is indeed a sign of a dramatic change in the Earth's environment.
Let's analyze the basic conditions for biological extinction:
1) Changes in temperature and environment.
2) Changes in the radiation environment.
3) Changes in the gravitational environment.
4) Breakage of the food chain.
Alterations in (1), (2), and (3) may lead to a break in the food chain.
Therefore, species extinction is usually a tendency for parts of the food chain to disappear. Those animals that crossed the food chain were able to survive and evolve into species that were more adapted to the environment at the time.
First of all, the era when dinosaurs lived, the earth's climate was hot. Due to the initial cooling of the climate, a large number of organisms are not adapted to the cold.
Extinct. Dinosaurs were most likely to become extinct due to temperature changes. It's just that the time scale of extinction is too short, people hypothetical.
An asteroid hitting the Earth also caused the Earth's climate to cool suddenly, and it was impossible to return to the state it was in before the impact.
However, it is not excluded that the Earth's climate will change a lot due to changes in the brightness of the sun. In fact, conceived on Earth.
In the course of life, it must have been after the massive impact of an asteroid on Earth. Otherwise, the earth's environment will not be very stable and life will evolve.
The route can be difficult to determine due to the drastic changes in the environment. In the age of the dinosaurs, it was certainly not a regular occurrence for asteroids to hit the Earth.
At that time, the probability of an unexpected event on the Sun was higher than that of an asteroid impact on the Earth. Solar Emergencies.
Not only will it cause changes in the temperature environment, but also sudden changes in the Earth's radiation environment, so a large number of species will inevitably be eliminated. Biological tests.
These suggest that changes in the radiation environment can cause rapid extinction or mutation of species.
Gravitational environmental changes are related to the density distribution of matter in the solar system. And the changes in the overall gravitational environment of the solar system may be related to the Sun in the Milky Way.
location. The evolutionary timescale in this area is very long and difficult to determine.
Anyone can put forward the hypothesis of the extinction of the dinosaurs. But it's the hypothesis that tests the most important thing.
The only way to test the hypothesis is to obtain concrete evidence through the archaeology of the solar system (including the Earth). Therefore, it is easy to come up with a hypothesis.
The search for archaeological evidence is difficult and exciting.
Exploring the mystery of the extinction of the dinosaurs is essentially exploring the mystery of the evolution of the solar system. This is by no means an isolated incident.

Dinosaurs were all extinct from the Late Cretaceous of the Mesozoic Era to the beginning of the Cenozoic Era from 60 million to 70 million years ago.
How did dinosaurs become extinct?
About 200 million years ago, the Earth was littered with large swamps. Deep valleys and hillsides are covered with dense forests. That's the footprints of dinosaurs all over the world. >>>More
Nonsense, the dinosaurs are extinct, and they are all over the streets.
It is the extinction caused by the asteroid hitting the earth, but this process lasts for up to 1 million years, when the asteroid hits the earth, the dinosaurs are not completely extinct in an instant, but the climate upheaval caused by the impact, the dense dust covers the sun, causing plants to be unable to photosynthesize, and the herbivorous dinosaurs are extinct after the plants die, and the carnivorous dinosaurs are extinct because they have no food.
