There's no reason to think that all adaptations are beneficial. Interesting though.

- scott_s 17y agoAdaptations are, by definition, beneficial. There will be evolutionary by-products, though; things that arise because of evolution, but there was no actual selection pressure for them. Some changes occur because of genetic drift, and others will be related to something else which was selected for.
- michael_dorfman 17y agoOK, let's rephrase, then: there's no reason to think that fingerprints are an adaptation.
- scott_s 17y agoYou mean there's not enough evidence either way. Which is why it's useful to investigate if fingerprints do have a benefit. If they do, then that's a compelling reason that they are an adaptation.
