According to the biological species concept, two organisms are of different species if they do not do which of these
The modern speciation theory
reproduce with each other
No, biological species concept is NOT useful for extinct organisms at all, nor organisms that reproduce asexually; it is only useful for organisms that produce sexually.
Organisms are the same species if the have the potential, or actually interbreed one with another. Does not apply to all organisms. Bacteria being an example of this. Is not as strong a concept as once it was as it did not adequately address hybridization.

Biological species concept :)
There are two main problems that can be identified in the biological species concept. This concept emphiasizes interfertility between organisms. However, reproductive barriers between sexual reproducing species are not always effective. Sometimes, individuals of different species interbreed and produce offspring call hybrids. Also this concept fails to describe species that are predominantly asexual in their reproduction, including all bacteria as well as some protists, fungi, plants, and even a few animals.

evolve
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.
biological species concept
Some organisms have no bones to leave behind. Even so, the conditions have to be perfect for a fossil to be formed: they have to die in a riverbed; no other animals can damage the bones; sedimants have to slowly build up without the bones being moved ; and finally they have to be discovered by a person.
