Species are often described as a group of people with similar traits, where they can breed to produce fertile offspring.
IMPORTANT CONCEPT OF SPECIES
The four most important concepts of species are:
Typological Species Concept
In this sense, there is a limited number of species of living things on earth. These types do not indicate any relationships. Such species are called species. This inequality is regarded as trivial and insignificant.
Aristotle and Plato propagated this idea in their philosophies. In 1954 and 1956, Cain adopted the concept of Typological species as the concept of morphospecies. Since members of species or taxes can be identified by their essential characteristics, a team of scientists refers to this as the concept of species.
The concept of Morphospecies states that species can be distinguished from other species by their own characteristics and can be identified by their morphological features. This is called the concept of morphological species.
Nominalistic Species Concept
The concept of species is called the concept of Occam and his followers, of the belief that nature produces the individual. Species are human nature. In nature, they have no definite existence. These theories have no scientific basis.
It is believed that these species have been developed to transmit to more people collectively. During the 18th century in France, this concept was needed and even now used by botanists.
Biological Species Concept
In the middle of the 18th century, a new concept called the biological species concept emerged. The idea was adopted in the latter part of the nineteenth century when Darwin’s book The Origin of Species was published (1859). This is also known as the Newer Species concept. Jordan was the first to invent the concept in 1905. Later in 1940, Mayr espoused this idea. According to this concept, “animal species are a breeding ground for natural species.” Mayr explained that members of a certain type display these qualities:
Reproductive society: For the purpose of reproduction people of a certain type recognize each other as potential mates.
Ecological Unit: The members of a species differ from many factors, but all members collectively form a unit. They interact with other species of animals as a unit anywhere.
Genetic unit: Animal species cover a large gap, which connects the genes, although the human being is a permanent vessel that covers a small portion of the genetic material for a short period of time.

EVOLUTIONARY SPECIES CONCEPT:
Biomedical errors have led paleontologists to develop the concept of evolution.
Simpson described it as “a kind of evolution that is a genetic (ancestral-genetic sequence) that evolves from one another and its role in the evolutionary process and its tendency”.
Wiley had given a revised definition of the concept of evolution. He asserted that “evolution is a by-product of the very existence of the human race from one generation to the next, and it has its own evolutionary tendency and end of history”.
Biodiversity forms the basic basis for how species are classified. They are the major biological components, in which two identical organisms of the same species reproduce in the reproductive process. Within the separation modes, there are karyotype, morphology, DNA sequence, etc. which helps to clarify and reduce biological biodiversity. This article discusses the imminent extinction of species and the impact it will have on the world’s biodiversity.
Extinction of Species:
Globally, in recent years, especially in the last few centuries, they have seen rapid growth in extinction rates. There is a general consensus in the scientific and anthropological sciences that these extinction rates may be directly related to human settlement over the years, as men begin to stop living a nomadic life and build a culture where they could settle down and engage in agriculture. and other such practices.
This period also represents the time when resources, especially natural resources, were viewed on the basis of the uses they provided. If a particular species was useful, such as cattle and goats, which meant that it provided benefits for food, or to raise money for the main sector, it was raised and maintained, but without their help, it was expelled. countries that have been occupied by European colonialism, population growth, population growth, etc. which led to the extinction of species by natural or man-made. Environmental degradation is based on “evolutionary” research, and man-made research is based on “invasive” research.
Currently, more than 31% of aquatic and aquatic animals, 12% of bird species and 20% of mammals are at risk of extinction according to the World Conservation Union’s (IUCN) international survey of all known species. Although these estimates exist, there is much debate about how many species are at risk, but there is general agreement that at least more than 1,00,000 species become extinct every year.
There are ways to determine the causes of extinction. At least based on the last five massacres, it can be noted that there are similarities between you, which can be listed as follows:
- There have been major environmental or bio-diversity losses around the world.
- The loss was rapid and rapid
- In effect, the effect of these events is not automatic, i.e. it affects large groups and all of the certain species and related species.
- The law of “survival of the fittest” did not follow, and some species that survived earlier could have become extinct.
- The massive extinction of the sixth is on the way, and understanding the conditions that could lead to such an extinction is necessary and necessary in today’s view, as the potential impact can be enormous and can affect people’s living standards.
