Evolution 

 Example of Evolution

Some Rabbits live in one place, the area in which these Rabbits live, the temperature of that area remains something or the other in the area where these rabbits are living. There will be light conditions, there may be 10 hours of light in a day, there is some rainfall condition in the area in which these rabbits are living. It rains inside that area, sometimes it rains more and sometimes there is a dry season, sometimes it rains less but it will rain.

Like the temperature of that area may change after 100 of years, the light condition of that area may change after 100 of years.

Evolution basically means ``changes`` or ``variation`` which accumulate at generation level

• Recombination-When homologous rabbits interact with each other, some DNA segment exchanges occur. Changes occur in gametes and end in gametes when such gametes fuse.

• Arrangement of Chromosome at Metaphase plate

• Independent Assortment

• Genetic Drift

• Mutation

• Natural Selection

Types of Evolution

1.Micro Evolution-Micro Evolution If there are very small level changes, then we will call it Micro Evolution. The mind is an individual and the body of that individual has many different organs and inside many different tissues, there are many cells. That is to say, the body of an individual is made up of millions of cells.That is, 46 DNA molecules are present inside each cell at that time, in 46 DNA molecules, 23 molecules are from the father's side and 23 molecules are coming from the mother's side. We know that the human bean is a diploid organ Diploid Organ in the Sense of Human Bean Has Two Copies of Each Gene

.

There is a single cell in the milion of cells of an individual. There is a total of 46 DNA molecules inside that cells.

There is a single cell in the milion of cells of an individual. There is a total of 46 DNA molecules inside that cells. There are many genes present in that DNA, we call those genes alleles. If a mutation occurs within a single allele of a gene in a single cell of an individual, then it is a change of allele level. If there is a change in it, then that individual will not even know that changes have happened inside his cells and that cell is that cell is eliminated, if there is a change in the other allele, then we will say that this change is up to the gene level. If there is a change in any one of the complete DNA of 46 DNA, then we will say that the change has started at the level of the chromosome. If changes occur in all the DNA of anyone cell, then it will be said that this change came above the cell level. If change comes inside the cell of that tissue, which is a part of that tissue, then it will be said that this change has come above the tissue level. After this the tissue which is part of the organ, if change starts coming in that tissue then it will be said that this change has come at the organ level. And similarly, if there is a change in an organ that is a part of that organ, then this change will be up to the organ level.

2. Macro Evolution- Large scale changes are called macroevolution as changes occur inside human bean-like changes occur inside human bean of her countries.

Evolution is the gradual, permanent change in the genome of an organism that occurs based on the ``present condition``.

What I am saying about evolution is that mutations should come slowly, these changes should be permanent and the changes should come to the genome according to the current situation.

From an ecological point of view, any living thing in nature cannot survive on its own. Any living organism that has the potential to survive can only survive in the modern world of any living thing because any human being survives the need of another human being. together, whether in its species or the interaction of other species, is extremely important.

Similarly, the topography of the area where the Rabbits are living, the topography of the area in the sense that there are mountains inside that area is a plain area. There is inside that area, rocks are lying inside that area, so whatever its structure is, how much slope is there, how high is the foot, it is called topography. The area in which the Rabbits are living is also the condition of the soil of that area, what type of soil is it? what is the salt condition in the soil? All these things are present where these Rabbits are living. All these things make up the non-living form environment of Rabbits.

The most important living form in this Rabbits surround should be the Plant because Rabbits will feed the Green Plant in the form of food. So there must be some plants in that area, some may be hubs, some may be subs, and some may be trees. Under which these Rabbits live by making their house, then there are some types of plants inside its area, along with these Rabbits some animals also live. Which are called plants which we call herbivores like deer, elephants, monkey, birds which live in the same area.

Where these rabbits live there may be a fox inside this area and the fox will feed it to the rabbits How many other life forms are present in this Rabbits' Surrounding and its Non-Living Forms Environment is there in this Rabbits Surrounding. There is a natural task in front of these Rabbits every day, that's a natural task may be Rabbits have to eat their food, if Rabbits have to eat food. So it will interact with the plant, if the rabbits are going to the area, then other herbivores may compete with them. If the fox has seen the rabbits, then it may be that by attacking the fox rabbits, we call this interaction, and the microbes that are there may be They may cause disease on rabbits.

So it will happen that when Rabbits interact with all those things, then eventually changes start coming in the Rabbits' genome over time. Finally, after a long time, when the new generation is grown, then after 100 of years, there are changes in the rounding of that population as well.

The topography, rifle, soil condition of that area may change after 100 years, a new plant may be grown, predators may come Some new microbes may come in given condition How is the present condition Always the organism struggles with its basic feet When an organism is struggling. Changes come in the body of that organism, we do not know that there are changes in our body, but what is the condition in our surroundings in today's date We are struggling on their basic, slowly these changes are found in our genome.

And as soon as these changes happen they pass into the next generation After time changes come so much Present day's organization is very different from what is now ancestral population organism, this is called evolution.

Changing with time, called evolution.
