The scientist can tell that punctured equilibrium has occurred if they have examined the fossil fuels and can see that one organism rapidly evolved different characteristics.
Answer: Option D
<u>Explanation:</u>
Punctured Equilibrium is an evolutionary theory which proposes that the species appearing in the fossil's record will show little evolutionary changes. In punctuated equilibrium, change occurs gradually, First very little change can be seen which later results in the occurrence of huge changes.
Such huge changes can be clearly seen by examining the fossil records. Thus if there is any evolutionary changes seen in the fossil's record, the scientist can conclude the occurrence of punctuated equilibrium.
The domain of the new species of unicellular microorganism in an undersea thermal vent that lacks a nucleus is Archeae.
<h3>What is domain?</h3>
Domain in biology refers to the highest rank in the classification of organisms, above kingdom.
The three domain of organisms are as follows:
- Prokarya or Bacteria
- Archaea
- Eukarya
Members of Prokarya and Archaea do not possess a membrane-bound nucleus, however, the major difference between them is that members of domain Archaea are found in extreme habitats e.g. hot regions.
Therefore, the domain of the new species of unicellular microorganism in an undersea thermal vent that lacks a nucleus is Archeae.
