What Must Be True For Natural Selection To Happen Apex – Natural selection, coined by Charles Darwin and Alfred Russell Wallace, is the modification of genetic material (DNA) over generations according to factors that help organisms survive and reproduce. This is sometimes called ecological adaptation or ecological adaptation.
Natural selection can be defined as the way in which species adapt to their environment to survive. Natural selection occurs when traits that make organisms in an environment easier to survive are passed from parents to their offspring.
What Must Be True For Natural Selection To Happen Apex
The idea that species change over time to survive in their environment is what natural selection is all about. This theory is the basis of Charles Darwin’s theory of evolution. Basically, natural selection occurs when changes in an organism’s DNA are beneficial. Such changes give the organism a competitive advantage.

Natural selection depends on the environment. Characteristics that are helpful in one environment may not be helpful at all in another. Organisms that are able to adapt to their environment are those that survive and pass on their genes to their offspring.
Charles Darwin showed that organisms with inherited characteristics that help them survive and reproduce will become more common in a habitat over time. This is the way to grow. Now that you have a better understanding of how natural selection works and how different species are created by natural selection today, think about the evolution of biology even more.

Natural selection is defined as the natural process by which organisms adapt and change according to environmental conditions. And organisms that adapt to their environment live longer and produce more children.

. These traits will then be passed on to subsequent generations. Over time, these traits will become more prevalent as they dominate other traits in society.
Naturalization (biological definition): The natural process by which organisms with certain genotypic characteristics that better adapt to the environment increase their survival, reproduction, numbers or frequency and, therefore, are able to transmit and maintain genotypic values. Characteristics for future generations.
Natural selection refers to the survival and reproduction of individuals. It is an important evolutionary process in which the genetic characteristics of a population change over generations.
The basic idea of natural selection is that people are naturally different, which means that everyone is different in some ways. This variation exists within living things, and change occurs at this time

Natural selection occurs when some of these changes help an organism survive and reproduce more than others, causing their genes to become more common in the population over time.
Since the environment is constantly changing, no organism is considered perfectly adapted or perfectly adapted to its environment. It will always select for certain things that have certain genetic combinations. This makes natural selection an important force in evolution.
. However, even if the parents are perfectly adapted to the environment, somehow the environment changes, their children try to adapt to the changing conditions in an effort to succeed despite limited resources and overcome competition with other citizens. At that time, the best organisms will be adapting and reproducing. As a result, those who are able to survive will be able to pass on their characteristics or genes to the next generation.
The genetic variation of an organism makes each person slightly different. These differences make them multiply themselves by creating people who are ready to succeed. Without these genetic changes, the body cannot reproduce any further. As a result, their lines are not at the end.

It makes citizens adapt to their environment in time. Individuals have mechanisms that help them survive environmental pressures, such as the presence of predators and the availability of food.
People who have inherited these traits will have more children in the next generation than their peers. These helpful traits will help them survive and reproduce. Resources are limited by nature, where people with good habits have increased over the generations.
. Some organisms with genetic variants that tend to increase survival have greater reproductive success than those with other genetic variants. Selection results from differences in survival, mating success, growth and fertility.
Natural selection is the process by which inherited traits increase an organism’s chances of survival and reproduction. Useful qualities are preferred over useless qualities.

The theory of natural selection is based on the direct observation of the British naturalist, Charles Darwin, during the voyage of the HMS Beagle around the world from 1831-1836. He noticed that the same creature shows a difference in appearance in different geographical areas. At that time, he partly proposed that such physical changes were adaptations of living things to their environment. But before Darwin’s theory of natural selection, there were other theories of evolution that needed to be explained.
Jean Baptiste Chevalier de Lamarck (1744-1829) was the first evolutionist to publish his view of the process leading to biological change. One of the attorneys of
, a theory that previously held that living things arose suddenly from inanimate matter and gradually evolved into more complex forms as they strived for perfection. (Darwin’s Evolutionary Theory, 2015)
, this theory was based on Lamarck’s theory that evolution was mainly due to the inheritance of characteristics when organisms adapted to their environment. (Darwin’s Evolutionary Theory, 2015)

, Lamarck asserted that evolution occurs when an organism uses an organ in such a way that it eventually changes during its lifetime. This change can then be inherited by its children.
He explained this principle to the giraffes who got long necks over time as an example. He believed that the ancestors of giraffes originally had short necks. As giraffes continue to stretch their necks to pick leaves for food, their necks get longer with each generation. This change in body shape may be inherited.
Another example is birds that fly like herons and egrets. They seem to have evolved by stretching their long legs to stay dry.
Lamarck also believed that living things can produce new organs that change the shape and function of old organs.
Survival Of The Fittest Vs. Natural Selection
However, this theory is no longer as popular as it was when it was criticized by modern evolutionary theory and research. Although his theory was wrong, he contributed to guiding the creation of scientific discoveries.
. However, he still believed that there was a form of life before. Cuvier was the first scientist to write about the extinction of ancient animals. He was an expert on dinosaurs. Cuvier believed that “
Another theory before Darwin was that of extinction. Its naturalists were Joseph Fourier and Comte de Buffon. This theory was based on the idea that catastrophic events changed the Earth. Degeneration experts believe that the Earth began as a hot ball of molten rock, which eventually cooled. (
This theory was opposed by Charles Lyell (1797 – 1875), an English lawyer and geologist while other naturalists linked the tragedy to the Bible. (

Lyell wanted to establish geology as a science without theological elements. Thus, he turned to the ideas of James Hutton which led to the idea of a school of thought,
Lyell said that the Earth experienced a slow process over time rather than a big crash. These gradual processes, such as weathering, deposition, lithification, etc., have changed the Earth as we see it today. He described this natural force as the force that changed the shape of the Earth’s surface.
Both Lyell and Hutton, however, saw Earth’s history as vast and pathless. Lyell believed that the processes that changed the Earth were stable over time.
As far as life history is concerned, it is not useful. However, this evolutionary theory contributed to Charles Darwin’s understanding of evolution in the 1830s. George Cuvier and Charles Lyell strongly rejected the idea of evolution in living things. Cuvier did not live long enough to know about Charles Darwin’s proof of evolution. However, Lyell heard about this and accepted this evidence in the early 1860s, and became a friend of Charles Darwin. Today, our world is shaped by catastrophic events that occur from time to time. All these events probably influenced the speed and direction of natural evolution.

During Charles Darwin’s journey, he noticed an interesting pattern in the distribution and physical characteristics of animals. One of these remarkable specimens that he saw was a species of mountain in the Galapagos Islands.
These birds were not alike, each species was well adapted to its environment and its role. For example, some birds that eat large seeds grow larger
