day 74 Microevolution and macroevolution

 What type of evolution is demonstrated in this photo?

• Coevolution

• Convergent evolution

• Punctuated evolution

• Gradualistic evolution

Answer explanation

The photo demonstrates coevolution, where two or more species evolve together in response to each other's influence.

The idea that evolution seems to occur in spurts of time.

• stabilizing selection
• gradualism

• disruptive selection
• puntuated equilibrium

Which best describes punctuated equilibrium?

• Speciation occurs due to natural selection

• Speciation occurs due to isolation

• Speciation occurs suddenly and rapidly in geologic time, followed by long periods with little evolutionary change.

The large-scale events of speciation are called...

• macroevolution

• simplification

• adaptation

• microevolution
