Even though sarcopterygians are fishes, they are the common ancestor of all the tetrapodes (we humans included).

In fact, every vertebrate have lobe-limbs that originated from the lobe-fins of the sarcopterygians, so in a very real sense er and all the vertebrates alive are descendants of the sarcopterygians <span>fishes that lived in the Devonian 419.2 million years ago.</span>

You are operating your powerboat near a shoreline. What should you do to help prevent erosion?
soldi70 [24.7K]
If you are operating your powerboat near a shoreline, what's important for you to do if you want to help prevent erosion is maintain wake speed to avoid swerving in a counter-clockwise direction.
