Assume you are studying the fossil record of a certain lineage of sharks. You find that sharks in this lineage will maintain the same morphology for long periods of time and only rapidly change their morphology during a speciation event. The evidence you uncover is supportive of which of the following theories? a. Punctuated Equilibrium b. Gradualism c. Start and Stasis d. Increased Net Tempo

is a theory which states that profound change is the cumulative product of slow but continuous processes: Gradualism Macroevolution Punctuated equilibrium Survival of the fittest

Question 45 The fossil record shows many examples when species remain constant for long periods of time, but then speciation episodes occur rapidly. This is indicative of allopatric speciation. punctuated equilibrium. sympatric speciation. gradualism.
