What are the options here?

This article is an interesting read.

Shock: First Animal on Earth Was Surprisingly Complex

Notice the two options given.

“Dunn says that two evolutionary scenarios can explain why the comb jellies would actually have been first among animals. The first is that the comb jelly evolved its complexity independent of other animals after branching off to forge its own path.

The second is that the sponge evolved its simpler form from the more complex form. This second possibility underscores the fact that "evolution is not necessarily just a march towards increased complexity," Dunn said.”

This second scenario is interesting. Your distant descendants may well be jellyfish, just like your ancestors were.

Well, there is another option…

  1. To Quote (from the article) "So shocking that we initially thought something had gone very wrong."

    Wonder what that could be?
