Evolution and a Prophecy - Part 02
Gradually primitive people started to spread all over the world. And they began to adapt themselves to each geographical environment. And the adaptation process began. Adaptation is actually a process in which animals and plants develop certain characteristics to survive in the geographical area in which they live. And this is why adaptation is said to be a primary step in evolution. Over millions of years of adaptation, animals have radically changed their unique characteristics. This process is very slow.
Consider today's modern man. Those who live in cold countries have to fight against harsh weather conditions to sustain their existence. When the same human species spread to some cold countries, some forested countries, some desert countries, some mountainous areas and some flat temperate areas, they gradually adapted themselves to survive in their respective environments.
To survive in the harsh climate of the cold country, they became taller and more physically powerful. Due to the lack of strong sunlight, the amount of melanin under the skin started to decrease. Because the function of melanin is to protect the human body from the intense heat of the sun. It is a type of dye. In excess of this, the skin color becomes dark black and in very low presence, the skin color becomes whitish. Therefore, the skin color of the people of the cold countries is white and the people of the desert countries of Africa are negroes.
Our country is in the temperate zone. We can sustain ourselves with very little effort. So, our body shape is not so tall like white and black people, medium. Our physical strength is also very less to reduce the effort. Not very bright sunlight like desert in our area. So our skin color is brown between white and black.
In the same way, in other animals also this special form of adaptation is very clearly observed. The hardest horse in the world is the Arabian horse. That is because they have adapted their own bodies in this way in the struggle to sustain themselves in the extremely hostile desert. Desert camels and Meru camels look completely different. But there is no doubt that they are camels. The hair on the desert camel is very short, like the hair on the cow. And on the camels of the polar region, huge hairs like horse hair, to protect from the cold.
The upper one is polar camel and the lower one is desert camel
Adaptation. A very important step in the beginning of animal evolution. Horses have gradually evolved to adapt themselves from the size of a cat to now giants. Seals, dolphins, whales have adapted themselves to make permanent abodes in water, but they were not aquatic creatures even in spacetime.
Every day we wake up to the sound of the beautiful birds, we are captivated by the wonderful beauty of the birds, but do we know what these birds were before? The ancestors of birds are the monstrous carnivorous dinosaurs. A class of dinosaurs could fly in that primeval age. All the dinosaurs were extinct but this flying dinosaur survived. They have evolved from the primitive environment and transformed into today's modern birds. It was the beginning of that adaptation. Massive meteorite and asteroid collisions ended the age of dinosaurs on primitive Earth. Primitive natural environment also disappears. Primitive dinosaurs evolved over millions of years to gradually adapt themselves to the changing natural environment to become today's birds.
In the next chapter I will discuss how adaptation leads to evolution. And, why dolphins are included in other animals despite possessing intelligence almost close to that of humans. Why man is the best creature of creation!
