I have a question concerning Nature’s evolution…is it there to frighten off predators, or is it there simply coincidentally. I’m referring to the vivid bull’s eye that a particular butterfly portrays on it’s wings. Lets us pretend that the butterfly’s huge fake eyeball evolved into what it seems like it is, from resistance of some sort…but such resistance would not be tangible. How could it evolve a defensive device though nature without a tangible necessity? For visual effects look at “download jigsaw puggles.com.” Gallery# 297
I know not, however, I'm waiting for the grass of the fields, blooms on the roses, birds in the air and waterfalls from the heights to all evolve into chocolate. Of course there would have to be a civilization of Umpa Lumpas to protect it's sacred nature. Ahhhhhh, nature's gooood!
I don't think anyone can say definitively. I think nature's first imperative is survival. Some creatures evolve features that make them look like leaves or sticks or even other animals, so they can prey on unsuspecting underlings. Others have anatomical features that are a deterrant to predators.
The other physical evolution involves males sporting 'features' to attract a female..some of them quite colourful, i.e. South American birds. It's also quite likely that many creatures see a completely different colour spectrum than we do, and can see others features that we can't..even with an ultraviolet filter.
Apart from the above reasons, there are probably many others that are known only to their species.
I don't think it's possible to fully understand animal behaviour. I find the commentary on these TV nature programs either a bit suspect or laughable. They're always making broad assumptions about various behaviours, while applying the same reasoning as human reactions to the same stimulous. The animals may have very different reasons for reacting to certain situations that we simply could not understand in the same way.
To frighten predators seems like a reasonable explanation. if they see what looks like a big eye then they may assume that it belongs to a big animal. But then they all have some kind of pattern, so it may be just coincidence that it looks like an eyeball.

I am having a hard time finding the right forum thread for evolution. I couldn't find a thread in the education area or the science area.Anywho, I got to thinking today about the fact that evolution is considered fact now and that there are evidences to prove where we come from. Then I got to...

Eyes supposedly evolved over millions of years in stages. If mutations are random, how likely is it that each new part "randomly" evolved in the exact spot it needed to be in to make the eye work?And for each type of eye, this supposedly happened multiple times independently. That's even...

It was long regarded that humans have done the majority of their evolving and have largely stopped because of the cushy way in which technology has influenced out lives. In characteristics like skin colour, lactose tolerance and capillary density in people living at high altitude it is obvious that...

If humans evolved from fish or chimpanzees, why are there still fish and chimpanzees?Many scientists agree that man evolved from fish or chimpanzees. If that is the case, why are there still fish and chimpanzees. Why are there not stages of evolution going on now? There may be a...
