Question

Certain foraminifera (shelled protozoa) have inconsistent fossil records. Which mode of evolution do they represent?

A. adaptive radiation
B. phyletic gradualism
C. puncated equilibrium

Answer 1

Punctuated equilibrium

Step-by-step explanation:

Punctuated equilibrium is a concept in biology which suggests that the population will become constant once a species appears in fossil record, indicating little evolution throughout its geological history.

Punctuated equilibrium is strongly opposed to phyletic gradualism,which usually belief that evolution normally occurs universally and through the steady and incremental transformation of the whole lineages

Answer 2

Punctuated equilibrium is a theory biology which proposes that once species appear in the fossil record they will become stable.
So according to above explanation C. puncated equilibrium , is the correct answer
