“In biology, a species is one of the basic units of biological classification and a taxonomic rank. A species is often defined as a group of organisms capable of interbreeding and producing fertile offspring. While in many cases this definition is adequate, more precise or differing measures are often used, such as based on similarity of DNA or morphology. Presence of specific locally-adapted traits may further subdivide species into subspecies.
The commonly used names for plant and animal taxa sometimes correspond to species: for example, “lion,” “walrus,” and “Camphor tree,” each refers to a species. In other cases common names do not: for example, “deer” refers to a family of 34 species, including Eld’s Deer, Red Deer and Wapiti (Elk). The last two species were once considered a single species, illustrating how species boundaries may change with increased scientific knowledge.
Each species is placed within a single genus. This is a hypothesis that the species is more closely related to other species within its genus than to species of other genera. All species are given a binomial name consisting of the generic name and specific name (or specific epithet). For example, Pinus palustris (commonly known as the Longleaf Pine).
A usable definition of the word “species” and reliable methods of identifying particular species are essential for stating and testing biological theories and for measuring biodiversity. Traditionally, multiple examples of a proposed species must be studied for unifying characters before it can be regarded as a species. Extinct species known only from fossils are generally difficult to give precise taxonomic rankings to. A species which has been described scientifically can be referred to by its binomial names.
Nevertheless, as Charles Darwin remarked,
‘I look at the term species as one arbitrarily given for the sake of convenience to a set of individuals closely resembling each other …. it does not essentially differ from the term variety, which is given to less distinct and more fluctuating forms. The term variety, again in comparison with mere individual difference, is also applied arbitrarily, and for mere convenience sake.’
Because of the difficulties with both defining and tallying the total numbers of different species in the world, it is estimated that there are anywhere between 2 million and 100 million different species.”

[ii] “…species of beetle…”
“Beetles are a group of insects which have the largest number of species. They are placed in the order Coleoptera, which means “sheathed wing” and contains more described species than in any other order in the animal kingdom, constituting about twenty-five percent of all known life-forms. Forty percent of all described insect species are beetles (about 350,000 species), and new species are frequently discovered. Estimates put the total number of species, described and undescribed, at between 5 and 8 million.
Beetles can be found in almost all habitats, but are not known to occur in the sea or in the polar regions. They interact with their ecosystems in several ways. They often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are prey of various animals including birds and mammals. Certain species are agricultural pests, such as the Colorado potato beetle Leptinotarsa decemlineata, the boll weevil Anthonomus grandis, the red flour beetle Tribolium castaneum, and the mungbean or cowpea beetle Callosobruchus maculatus, while other species of beetles are important controls of agricultural pests. For example, coccinellidae (“ladybirds” or “ladybugs”) consume aphids, scale insects, thrips, and other plant-sucking insects that damage crops.”

[iii] “One species does not evolve to become another species, as the Earth textbooks indicate, without the intervention and manipulation of genetic material by an IS-BE.”
“Genetic engineering, recombinant DNA technology, genetic modification / manipulation (GM) and gene splicing are terms applied to the direct manipulation of an organism’s genes. Genetic engineering is not to be confused with traditional breeding where the organism’s genes are manipulated indirectly. Genetic engineering uses the techniques of molecular cloning and transformation. Genetic engineering endeavors have found some success in improving crop technology, the manufacture of synthetic human insulin through the use of modified bacteria, the manufacture of erythropoietin in Chinese hamster ovary cells, and the production of new types of experimental mice such as the oncomouse (cancer mouse) for research.
Since a protein sequence is specified by a segment of DNA called a gene, novel versions of that protein can be produced by changing the DNA sequence of the gene. The companies that own the modified genome are able to patent it. In the case of basic crops, the companies gain control of foodstuffs, controlling food production on a large scale and reducing agrobidiversity to a few varieties. The only apparent interest in promoting this tecnology appears to be purely economic, despite the claims of seed companies such as Monsanto and Novartis to solve the world food scarcity. It is now popularly understood that it is not the lack of food on a wholewide scale that is the main problem, but its distribution, aggravated by prohibitive tariffs by rich nations. Genetically modified crops do not reduce hunger. The majority of genetically crops are destined for animal food to meet the high demand for meat in developed countries. No genetic modification have yet to serve the needs of mankind despite all the promises in this direction.
However, even with regard to this technology’s great potential, some people have raised concerns about the introduction of genetically engineered plants and animals into the environment and the potential dangers of human consumption of GM foods. They say that these organisms have the potential to spread their modified genes into native populations thereby disrupting natural ecosystems. This has already happened.”
