Which of the following did not happen in the devonian period

evolution of amphibians

evolution of terrestrial vertebrate

rise of forests

none of the above

The answer is actually none of the above. The Devonian Period allowed for amphibians to evolve, as well as terrestrial vertebrate. Forests grew to cover most of the continent. All of these events happened in the Devonian Period.

The correct answer is none of the above.

Explanation:

Devonian is a geological time period, spanning 6. billion years from the end of the Silurian, 41.92 million years ago. The first known forests on Earth, rise in the Late Devonian, initiate with the evolution of Archaeopteris.

The first main amphibians evolved in the Devonian period, around 37. billion years ago, from lungfish like fish known as lob-finned fish.

The late Devonian also is known for the first four-leg vertebrates with true pods that could able to walk on land.

Thus, the correct answer is none of the above.
