Paradoxes:
* Two organisms "supposed to be"of the same species, and both masculine, cannot breed together, so they can't be of the same species. * If an organism "A" can breed with two other organisms "B" and "C", it means that "A", "B" and "C" all (appear to) belong to a single species, but not necessarily "B" and "C" must be capable of breed together, meaning that "B" and "C" belong to different species.
Biological species concept, phenetic species concept, reproductive competition species concept, evolutionary species concept, and the recognition species concept.
The two primary definitions of species are the biological species concept and the morphological species concept. The biological species concept defines a species as a group of organisms that can interbreed and produce fertile offspring, emphasizing reproductive isolation. In contrast, the morphological species concept classifies species based on physical characteristics and structural features, regardless of reproductive capabilities.
Multiple definitions of species are necessary because the concept of a species is complex and varies across different biological contexts. For instance, the Biological Species Concept focuses on reproductive isolation, while the Morphological Species Concept emphasizes physical characteristics. Different organisms, such as plants, animals, and microorganisms, exhibit diverse reproductive strategies and evolutionary patterns, necessitating various criteria for classification. Additionally, the flexibility in definitions allows scientists to adapt to new discoveries and understand speciation processes better.
Biological Species Concept, which defines species as groups of interbreeding populations that are reproductively isolated from other groups.
The main difference between the typological species concept and the morphological species concept is that the typological species concept classifies organisms that share characteristics that set them apart from others, whereas the morphological species concept classifies them as the same species if they appear identical.

Species (under the Biological Species Concept).
According to the biological species concept, two organisms are of different species if they do not do which of these
The Biological Species Concept identifies species based on the absence of interbreeding and the presence of reproductive isolation mechanisms. This concept defines a species as a group of organisms that can interbreed and produce fertile offspring.

The morphological species concept differentiates species by their physical traits, basically. The biological species concept defines a species as generally organisms that breed with others of the same species; rather a genetic isolation concept. The phylogenetic concept is based on evolutionary relationships and is the concept used by cladists.

interbreeding capabilities
Can mate with other individuals of their species and have viable progeny.
Two limitations of the biological species concept are that it cannot be applied to asexual organisms or fossils, and it may be difficult to determine reproductive isolation in some cases where different species can still interbreed and produce viable offspring.
