The "ring of life" model presents a network-like structure for the evolution of archaea, bacteria, and eukaryotes, considering horizontal gene transfer and genomic fusion, offering a more comprehensive view than the traditional tree model.
The "ring of life" model is considered more appropriate than the traditional "tree of life" to describe the relationships between archaea, bacteria, and eukaryotes because it suggests all three domains evolved from a pool of primitive prokaryotes in a network-like structure rather than a linear progression.
This model takes into account horizontal gene transfer (HGT) and genomic fusion, which are common mechanisms in the evolution of prokaryotes. While the traditional tree model emphasizes linear descent, the ring model acknowledges the complexity of genetic interactions and shared ancestry among the domains.
Overall, the "ring of life" provides a more comprehensive and interconnected view of evolution, highlighting the dynamic nature of genetic relationships across different domains of life.
