The extinction of dinosaurs was not instantaneous but lasted for a long time, long and long, up to millions of years. And the dinosaurs did not Perish.
In fact, the extinction of dinosaurs is an inevitable trend, even without the impact of the asteroid, they will perish or evolve, this is the evolution of the natural law of development Revealed.
All species have a process of birth, rise, maturation, decay, evolution, and Extinction. from Earth billions of years ago the earliest appearance of life, to now the earliest species has not been, a generation of constant change, only Today’s appearance. The so-called extinction of dinosaurs also follows this rule.
There are many hypotheses about the extinction of dinosaurs, and the scientific community has been arguing about it.
Among them, there are climate change, species struggle, continental drift, geomagnetic change, plant poisoning, acid rain, meteorite impact and so on.
A higher degree of identity is a statement of environmental change and meteorite impact.
These statements all have certain reason, in particular, the environmental changes led to a large drop in temperature, atmospheric oxygen drop, swamp reduction, and other factors make dinosaurs such a large size of animals have been completely unable to adapt to the shortage of food and fighting increased the difficulty of survival, this time a 10 kilometers of asteroids hit the Earth. By the time of the crash, the dinosaurs died in large areas, and the survivors had undergone millions of years of evolution, which had completely changed.
So strictly speaking, dinosaurs were not completely extinct. Scientific research has proved that the birds are now originated from dinosaurs, we are familiar with the chicken, its skeleton still retains the shadow of the dinosaurs.
Dinosaurs first appeared 240 million years ago in the Triassic, extinct in the Cretaceous 65 million years ago, before and after survival dominated the Earth ecosystem for more than 170 million years, this is already a very fortunate species. Moreover, they are not extinct, their offspring-birds are still sharing with us today’s Earth, live and multiply.
The time of human appearance is only millions of years, now is already crisis heavy, we will have the dinosaur lucky?
Evolutionary evolution continues, what will we humans become in the future?
We would like to discuss with you together.
