Nature always takes our test. And see if we are able to live in his created universe or not? The person who passes this exam live this nature. And the one who fails in this examination has to disappear. Because nature always chooses us for itself.
Hello friends, welcome to the "Value of Nature" and I am your friend Nitesh. And in this topic we will learn about an important reason for the natural selection.
Charles Darwin spoke about the natural selection in his revolutionary book "Origin of Species". Which made us understand a lot about the evolution. First of all, we know that what is the natural selection? Actually it is a small difference between two different looking species. It is possible that you too may not have understood correctly what is natural selection? So let's know it better in detail.
Charles Darwin traveled around the world before writing Origin of Species. And he had also studied beings that looked alike. He had said that the same species found on the island are also found on the mainland. But the two are slightly different. Now you must be wondering why? Actually, we call it natural selection. Where animals adapt themselves to the environment and geographical conditions. This change is slow but it is 100 percent correct. And many scientists have also proved it in the lab. The species living on the island molded themselves according to the island, and the species living on the same Mainland molded themselves according to the mainland. And this is why there is a difference between the two. In these species, the one who adapts himself according to the atmosphere and geographical situation, he is able to live. And are able to extend their existence to the second generation and this is the "Law of Nature".
Let's understand this a little easier from an example. Assuming there were two Giraffes, one had a long neck and the other had a short neck, when both of them had children, obviously the offspring of a small Giraffe would have been born with a shorter neck, and the longer Giraffe had a long neck. Must have been born with. Now the long-necked Giraffe used to easily eat the leaves of tall trees, and those with short necks were unable to do so. Now those Giraffes with short necks could not eat properly, then their species started fading naturally. And the long-necked Giraffe survived. We call it natural selection. Because nature had chosen them, and this is the reason that there are only long-necked Giraffes left around us.
Hopefully, you must have understood natural selection, and also understood why it is important for evolution.
