#metamorphosis — Public Fediverse posts

So if I understood this article correctly, the key conclusion is this - metamorphosis was not the condition for moving onto land?

The traditional picture was:

Tetrapods could leave water because they first evolved a tadpole-like larval stage and then metamorphosed.

The new interpretation suggested by these fossils is closer to:

Tetrapods gradually adapted to land over evolutionary time, and they probably did not need a frog-like metamorphosis to do it.

In other words, metamorphosis was probably not a prerequisite for terrestrial life. Instead, the transition from water to land appears to have been a long, gradual evolutionary process affecting the whole life cycle, rather than depending on a distinct larval stage.

Analogy of two possible scenarios:

Old model

• Young live in water.
• Undergo a major developmental transition.
• Adults become adapted to life on land.

New model

• Young and adults share the same basic body plan.
• Land adaptations accumulate gradually over millions of years (generations).

So the narrative shifts from:

Metamorphosis enabled the move onto land

to:

The move onto land happened gradually, and amphibian-style metamorphosis likely evolved later as a specialized adaptation.
