The evolutionary factors that should be considered in debating whether or not the biological species concept can be applied to bacteria. Introduction: Biological species concept (BSC) is a widely accepted concept for species. It defines the concept of species as a group of species whose members are capable of interbreeding but isolated from others on the basis of their reproductive abilities.

Introduction: Biological species concept (BSC) is a widely accepted concept for species. It defines the concept of species as a group of species whose members are capable of interbreeding but isolated from others on the basis of their reproductive abilities.

Expert Solution & Answer

Explanation of Solution

Biological species link species to the evolution process as the interbreeding species share a common gene pool. The DNA recombination takes place instead of gene exchange between different species. This recombination results in the evolution of species. This concept helps to maintain the species uniformity, and it is applicable for large, complex creatures consisting of gametes.

In the single-celled organisms, such as bacteria, reproduction occurs mainly by asexual means. In bacteria, horizontal gene transfer takes place (transfer of genome from one bacterium to another). Since in this process, the only transfer of genetic material occurs, so it does not explain the evolutionary process, and therefore such species cannot be grouped together. The asexual reproduction bypasses the standard evolutionary process explained in the concept. Hence, the biological species concept (BSC) is not applicable to bacteria.

Students have asked these similar questions

If a bacterium using aerobic respiration was to degrade one small protein molecule into 8 molecules of pyruvic acid, how many ATP would that cell make? Assume there is no other carbon source. Units cannot be entered in this style of question but the units of your answer should be in molecules of ATP.

If a bacterium using aerobic respiration was to degrade a 30 mM solution of citric acid, how many ATP would that cell make? Assume no other carbon source is available. Units cannot be entered in this style of question but the units of your answer should be in mM of ATP.

How much ATP will be produced during the following metabolic scenario: Aerobic respiration of a 5mM lipid solution that is made up of one glycerol and an 8-carbon fatty acid and 12-carbon fatty acid. Recall that when glycerol breaks down to Glyceraldehyde-3-phosphate it costs one ATP but your get an extra FADH2. Every two carbons of a fatty acid break down to one acetyl-CoA. (pathways will be provided on the exam) Units cannot be entered in this style of question but the units of your answer should be in mM of ATP.
