Which Idea Is Central To The Biological Species Concept?

The biological species concept (BSC) was designed to aid understanding of biological diversity, particularly the ubiquitous observation that sexually reproducing organisms exist in more or less distinct phenotypic and genetic clusters rather than in a continuum of forms.

What is the biological species concept?

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.

Where is biological concept of species is mainly based on?

A species can be defined as a group of closely related organisms which are capable of inbreeding to produce fertile offspring. Thus biological concept of species is mainly based on reproductive isolation, which preserve the integrity of the species by checking hybridization.

What is the unified species concept?

A unified species concept can be achieved by treating existence as a separately evolving metapopulation lineage as the only necessary property of species and the former secondary species criteria as different lines of evidence (operational criteria) relevant to assessing lineage separation.

Which idea stems from the theory of evolution?

The theory of evolution is based on the idea that all species? are related and gradually change over time. Evolution relies on there being genetic variation? in a population which affects the physical characteristics (phenotype) of an organism.

Which of the following is the best biological definition of a species quizlet?

1. A species are organisms that can interbreed with each other & produce fertile offspring (old definition).

How is the biological species concept tested?

In order to be considered to be a single species in the biological species concept, a group of organisms must produce healthy, fertile offspring when they interbreed.

Which of the following explains the concept of a species?

Species in terms of biological concept was given by Ernst Mayr. In his statement he defined that ” Those members which have ability to produce fertile offsprings, will belong from same members and from same species those which can interbreed among themselves.

What is the difference between the biological species concept and the phylogenetic species concept?
