I recently learned this from BBC's Life in Colour documentary. It explained it, similar to the article (although the paper really dances around this hypothesis), that the flies had a hard time landing due to some visual weirdness from the stripes when the flies are close up. They had a lot of close-up footage of flies hovering above a zebra's skin but seemingly confused on how to land.
- SoftTalker 4y agoI wonder why, over the long term, the flies did not adapt to this.
- gcanyon 4y agoOr the short term -- flies have much shorter generations. That doesn't guarantee faster evolution, but it helps.
- jabl 4y agoMaybe the adaptation would require significantly more advanced visual processing with attendant increase in weight, size, and energy consumption, making it not worth it?
- miohtama 4y agoMaybe compound eyes have some inherit flaw that makes it harder to process visual signal of stripes.
- aeternum 4y agoOur eyes can also be confused by relatively simple patterns: http://brainden.com/images/ricewave-big.gif http://brainden.com/images/ricewave-big.gif Intuitively, it does seem like stripes would make it more difficult to achieve focus for a compound eye, similar to how when looking through a chain-link fence or window screen it's easy to focus the wrong plane due to the spaced repetition.
- bmitc 4y agoVision is weird. It's things like this that, in my opinion, showcase the idea that our perception of reality is sculpted by our physiobiology.
- yarg 4y agoIt's deeper than that, not sculpted by - entirely defined by. You're a lump of electrical fat wrapped in a fortress of bone, running an internal approximation of the localised world outside. And from within this fortress, with its little holes for light, you control a robot made of meat.
