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.

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

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?

You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.

You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
