A biological species is a group of organisms that can reproduce with one another in nature and produce fertile offspring. The term species can also be defined as the most basic category in the system of taxonomy.

What is the best biological definition of a species?
The biological species concept defines a species as members of populations that actually or potentially interbreed in nature, not according to similarity of appearance. Organisms may appear to be alike and be different species.
How is a species defined according to the biological species concept quizlet?
The biological species concept defines a species as. group of populations whose members have the potential to interbreed in nature and produce viable, fertile offspring members of other populations.
How do you define species?
A 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. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche.
Who gave the definition of species?
Abstract. Ernst Mayr played a central role in the establishment of the general concept of species as metapopulation lineages, and he is the author of one of the most popular of the numerous alternative definitions of the species category.
What is the difference between the biological species concept and the phylogenetic species concept?
the ability of two individuals to successfully produce viable, fertile offspring (biological species concept) whether individuals look similar (morphological species concept) how closely related individuals are evolutionarily (phylogenetic species concept), and.
How many definitions of species are there?
There are seven distinct definitions of “species”, and 27 variations and mixtures. And there are n+1 definitions of “species” in a room of n biologists.
What is the biological definition of a species quizlet?
A species are organisms that can interbreed with each other & produce fertile offspring (old definition). 2. A class of individuals having some common characteristics or qualities; distinct sort or kind.
Who first defined the concept of species quizlet?
-The biological species concept is synonymous with the morphospecies concept. -The biological species concept was first described by Charles Darwin. A population of rare frogs is reduced by 90% in number when a large dam is constructed that obliterates most of their prior habit.
What is a species composition definition?
Species composition, the relative abundance of different. species (or of different functional groups of species), has long. been a key measure for evaluating biological communities.
What is a biological species example?
According to the most widely used species definition, the biological species concept, a species is a group of organisms that can potentially interbreed, or mate, with one another to produce viable, fertile offspring. For example, when a female horse and a male donkey mate, they produce hybrid offspring called mules.
Why is the definition of species important?
Species are important because they represent an important level of integration in living nature. This recognition is fun- damental to pure biology, no less than to all subdivisions of applied biol- ogy. An inventory of the species of animals and plants of the world is the base line of further research in biology.
Which introduced the biological concept?
The term species was just used as a term for a sort or kind of organism, until in 1686 John Ray introduced the biological concept that species were distinguished by always producing the same species, and this was fixed and permanent, though considerable variation was possible within a species.
Species is an ecological unit that interacts as a unit with other species which shares its environment ” • 3. Species is a genetic unit that consists of a large gene pool where as an individual is merely a temporary vessel holding a small portion of a gene.
What is genetic species concept?
We define a genetic species as a group of genetically compatible interbreeding natural populations that is genetically isolated from other such groups. This focus on genetic isolation rather than reproductive isolation distinguishes the Genetic Species Concept from the Biological Species Concept.
