The theory of evolution, these yards and this field!! 

In the science of biology, the definition of a species is that organisms of the same species can reproduce through sexual intercourse. Sometimes it happens that two similar species can produce offspring through sexual intercourse, but the offspring cannot reproduce. An example of this is a mule born from a donkey and a horse. A mule is not a breed because mules cannot reproduce themselves. But if we go to the past, the ancestors of horses and donkeys were the same, from which they were divided into two different species. 

The division of species in evolution is called speciation. Feel free to ask the Google Baba in which living organisms past and present examples of this have been found. This is the main point in the theory of evolution. In this regard, the childish argument of the critics of evolution is that if in the past one animal species split from another animal, why is it not happening today? Answering whoever makes this criticism is like banging your head against a wall because the question itself is evidence that the critic has zero knowledge of evolution. Because evolution does not happen like an animal slept today and woke up tomorrow morning, it was a different species of animal. In evolution, changes in an organism's genes and DNA occur over time, and only those organisms that have undergone changes that adapt them to survive in their environment survive to the next generation. Let's take an example like this. 

Suppose a crab develops some marks on its outer shell that are purely coincidental. Now, if the fishermen in the area where such crabs are hunted throw back into the sea those crabs whose outer shell marks even remotely resemble the human form, such crabs will increase in that area of ​​the sea. Because the fishermen will not catch them. The more a crab's outer shell matches the human form, the more likely the crab will survive and not be caught. So with time, these crabs will become more than the rest of the crabs. This is called a choice. In this case, the choice was made by humans, fishermen. This is a special species of crabs that are found in the seas of Chapan, they are called Heikegani. But the same selection when it is done by natural factors in the environment is called natural selection. The theory of evolution actually stands on these two pillars. Repeated changes in a DNA. Secondly, due to these changes, adaptation of the characteristics of organisms to the environment. 

So if someone asks you to show one species to another species in one day or one week, then answer him that it takes nine months for a child to be born. It can be said that the birth of the child is actually a lie. Children are not born, they fall from the sky. 

Personally, I don't like to discuss evolution because it is a theory that has been proven in many ways, not just today but for centuries. It has been extensively researched, many scientists have spent precious years of life on it and more research is proving it day by day. Proving evolution is like reinventing the wheel or proving Newton's laws. 

Be it Newton's laws or Einstein's theory or the theory of evolution, there is scope for academic discussion on all of them, but to reject them completely would be academic misconduct. If anyone wants to reject them, it is this yard and this field. Instead of disproving them on Facebook, do experiments in laboratories. Collect evidence, write articles, do research and reject all the evidences found in favor of evolution one by one. Who has stopped? This is the way to acquire new knowledge in science. Scientists don't like to argue against the laws of nature, just to contradict someone's theories. Can anyone make a plane fly by making Newton's laws by himself or can someone make a red GPS system of mine by rejecting Einstein's theory? So Bismillah. Foaming at the mouth or ranting on Facebook does not change the facts. Learning science seriously takes time. Evolution is relevant today because this theory helps us understand the scientific way of thinking that honestly knowing the full facts is just another name for science, whether one likes it or not.
