- Evolutionary Species Concept.
- Taxonomic Species.
- Microspecies.
- Biological Species.
- Evolutionary Species.
Are species arbitrary or real?
Species are not real in an evolutionary sense. They are man-made concepts that help us categorize nature’s diversity. Some species are very distinct, others less so. Deciding on a scientifically objective, robust and replicable way to determine that distinctness is the only way to make taxonomy scientific.
