What is convergent evolution and how is it different from horizontal gene transfer?
Microbial diversity understood from the functional diversity and phylogenetic diversity. The phylogenetic diversity deals with evolutionary relationship that exists among the microbes. The functional diversity deals with the forms as well as the functions because they are associated with microbial ecology and physiology.
Explanation of Solution
A common functional trait shared between different microbes, which have different 16S ribosomal RNA gene sequences that has occurred due to three reasons. They are horizontal gene transfer, convergent evolution and gene loss.
Convergent evolution defined by the occurrence in which single trait or groups of traits that are alike in function or forms between two organisms but they are not inherited from a common ancestor. This is different from horizontal gene transfer, where the genes that code for a particular trait are homologous and replaced by distantly related ancestors.
