Evolution: a different view with loss of traits; jellyfish (Introduction)

QUOTE: "'These findings provide further evidence that evolution doesn't necessarily make the genetic code more complex," said Gold, a lead researcher on the genome study. "Jellyfish can build a big, complex life history using many of the same genes found in simpler animals." (David's bold)

DAVID: Note my bold. Advances in evolution can use old genes and not more complexity of genes! Devolution is real.

dhw: Already covered earlier. It is perfectly logical that different environments will make some earlier features redundant. Organisms living underground don’t need eyes, filter-feeders don’t need teeth, and jellyfish don’t need some of the complexities that they may have inherited from their descendants. So what? Do you really think that humans devolved from bacteria?

DAVID: I need to see Behe's evidence. He is a very bright guy, not to be dismissed.

Fair enough. No hurry!
