Question

Which phylogenetic model proposes that all three domains of life evolved from a pool of primitive prokaryotes?

a. tree of life

b. web of life

c. ring of life

d. network model

Short answer

Option : (c) ring of life.

Step-by-step solution

Introduction

Prokaryotes are the simplest creatures that can survive in a wide range of environments, some of which are so harsh that no other organism can survive.

Explanation to correct option

Option (c) is referred to as the ring of life. All species, or the three domains Archaea, bacteria, and Eukarya, are said to have evolved from a pool of primitive prokaryotes, according to the ring of life hypothesis of evolution. As a result, option is the proper response (c).

Explanation to incorrect options

The tree of life is offered as option (a). The maximum parsimony approach is used in Tree of Life to connect several known species and to create a phylogenetic tree. As a result, choice (a) is erroneous.

The term "web of life" is used to describe option (b). According to the Web of Life, prokaryotes originated from a variety of species rather than a single primordial prokaryote. Option (b) is thus erroneous.

The network model is option (d). It does not suggest that all life evolved from a pool of basic prokaryotes. Option (d) is thus erroneous.

Conclusion

All three domains of life, Archaea, Bacteria, and Eukarya, are thought to have evolved from a pool of primitive prokaryotes, according to the Ring of Life theory.
