Metazoica back-up

This is an interesting article that showed up in my feed today. This asks the question of whales and dolphins evolving back to becoming land animals. I must admit, and I don't talk about families I've deleted over the years of working on Metazoica, but I thought about what it would be like if dolphins evolved back to being land animals. But I threw that idea away way back in the days. Because it just doesn't make sense. I've had several ideas since I started this project in the early 90s that I've thrown away. But the one that applies to this is those families. I thought IF whales and dolphins were to revert back to being land animals, they'd have to walk on their forelimbs. They do still have the same bone structure as land-dwellers' feet. But that kind of over-dramatic reverse evolution could never happen. Anyway, this is the article I found...

 I found this article very interesting. It's been buzzing around all week. I knew we could not be the only speck of dust in space that has life. It works out so well, there has to be other life somewhere out there! My question is what are they like? Are there predators and prey? Do they have epochs like we did here, where classes of animals go extinct to be replaced with new lifeforms? What do the dominant lifeforms of those planets think of their own wildlife? Do they really come visit us once in a while? So many things to think about! Now we can think about it more seriously thanks to this group of scientists and astronauts.
