[edit] Opponents of evolution
Apart from the fact that "argument" against evolution doesn't actually make sense, who cares about every little criticsm the Flat Earthers have about scientific explanations of biology? On a zoological entry all that matters is science, not religion.

- I'd say its important to keep some form of this, as the fish is an excellent example of evolution. I'm rewriting it though, to give what I hope is a more balanced view. In particular, the bit about it being evidence of god's creation deteriorating since "the fall" is a tiny minority view, and completely in unacknowledged contradiction to the rest. the section is also entirely unsourced.

[edit] Why is blindness advantage
The text sugests it is an advantage because that way the fish can use the energy devoted to the development of the eye in feeding, breading, etc..
It seems to me that the real reason is because the lack of that sensitive and soft tissue with no use, is an advantage in a dark cave were the eyes could be hurt and infect. (Sorry for the english)
- That is a perfectly valid suggestion, and well worth adding to the text. The only criticism I might make is that many deep sea fish have no eyes, but they do not bump into things. Your English is fine! Please go ahead and make any changes! We all make mistakes here, and other people fix them for us. Cheers, Neale Neale Monks 23:39, 7 November 2006 (UTC)
- I hope I've adressed this issue in my edit - there's currently no single definitive answer as to the advantage of losing the use of eyes. In fact there's several. But the fact that there's more than one contender shouldn't be interpreted to mean there's no reason why they shouldn't - quite the contrary. On the issue of bumping into things: 1. like many aquarists who have kept such fish, I can verify they are perfectly good (shoaling) swimmers, and studies show they compensate by using other, heightened senses. 2. still, fish living in caves inevitably face more potential bumps than creatures living in the open ocean - however deep - where there is almost literally nothing to bump into.
