Natural selection

Life in this world undergoes changes. changes are influenced by the law that occurs. So in this life adaptation and natural selection apply.
As we know from school lessons, life on this earth doesn't just exist. it goes through a process of historical annihilation. From when the earth is still hot, then single-celled living things appear until giant animals emerge.
Dinosaurs lived on Earth in an age called the Mesozoic Era. This era lasted 252 to 66 million years ago.
The Mesozoic Era is divided into 3 Cretaceous, Jurassic, and Triassic periods.
The Cretaceous period occurred 145 to 66 million years ago.
The Jurassic Period occurred around 201 to 145 million years ago.
The Triassic Period, which became the beginning of this era, occurred in 252 to 201 million years ago.
Triassic and the Great Continent of Pangea. Pangea is when the earth still consists of one land that has not been divided as it is now.
Early emergence of dinosaurs occurred in the Triassic period.
At that time many living beings began to live on land.
In this period the Earth consisted of a large continent known as the Pangea Continent.
Reptiles breed easily and spread throughout the continental continent.
In a new place of life, living things adapt and become new species.
In the Jurassic period, the Pangea continent was divided into 2 parts due to the movement of the Earth's crust.
The northern part of the land becomes the Laurasia Continent. Which in the south becomes the Gondwana Continent.
In the Jurassic period, living things that we know as dinosaurs reached their greatest body development.
But the ongoing life changes. extreme climate and lack of food make competition among animals more fierce. Plant-eating animals lose their suitable habitat and must avoid predators. This is where the law of nature applies, who is strong he who wins. Animals compete to survive. Nature does the selection and who can survive then he will be able to continue his life.
Moreover, then there is a theory that says meteor showers that made the extinction of these ancient animals.
