A species ( pl.: species) is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. [1] . It is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity.

A species is a group of organisms that share a genetic heritage, are able to interbreed, and to create offspring that are also fertile. Different species are separated from each other by reproductive barriers. These barriers can be geographical, such as a mountain range separating two populations, or genetic barriers that do not allow for reproduct...
Polar bears and Grizzlies
Oftentimes the only barrier to reproduction is geographic, or based on the physical location of the animals. If this changes, the animals can interbreed, and may merge into one species. This is currently being seen in the wild in polar bears and grizzly bears. As the climate changes, polar bears are forced further south, and must start exploiting different food sources. The change in climate also allows grizzly bears to venture further north, encountering polar bears along the way. The previo...
Dogs and Wolves
Still other animals, like dogs and wolves, are still technically the same species. While they have the same number of chromosomes and could technically breed, the domestic dog has come a long way from its wild counterpart. Dogs have not only evolved to be more cuddly and soft, but are attuned to human social cues. Wolves operate in a much different social structure. As such, the two are very unlikely to breed in the real world. However, because they can create fertile offspring, scientists co...

Domestic ferrets and wild black-footed ferrets look almost identical. The black-footed ferret, Mustela nigripes, is native to North America. The domestic ferret, Mustela putorius furo, is native to Europe and only exists in captivity in North America. Could these two populations be one species? A. No B. Yes C.Maybe 2.

May 10, 2024 · Species, a level of biological classification comprising related organisms that share common characteristics and are capable of interbreeding. According to standard taxonomic conventions, every species is assigned a standard two-part name of genus and species.

However, the classification of a species can be difficult—even riddled with controversy. Grades. 9 - 12. Subjects. Biology, Ecology, Genetics. Image. Polar Bear.
A species concept is, therefore, a working definition of a species and/or a methodology for determining whether or not two organisms are members of the same species. In this section, we will consider three species concepts that are commonly used by scientists.
Sep 24, 2022 · A biological species is defined as a group of individuals that, in nature, are able to mate and produce viable, fertile offspring. There are other definitions of species but, according to the …
The definition of what a species is--and to some extent, what an individual is--does not have a clear consensus among taxonomists. I will illustrate this with a genetic definition, a biological definition, and an evolutionary definition of species.
