DailyDirt: Nature Creates Some Cool Stuff
from the urls-we-dig-up dept
Insect evolution is pretty amazing in general, but there are a few examples that are almost incredible. For example, people have discovered enormous ant colonies, wasps that can create zombies, and the ways that insects exhibit a collective intelligence that looks surprisingly smarter than any individual bug. Considering that insects, by weight and numbers, surpass humans by at least an order of magnitude, we might want to keep an eye on these invertebrates. Here are just a few more fascinating examples of awesome insect abilities.
- An insect known as Issus coleoptratus apparently beat humans to the invention of the mechanical gear. This bug uses its gear mechanism to lock its hind legs together so that it can jump straight forward, and this is the only known example of a naturally-occurring gear in nature. [url]
- The dung beetle, Scarabaeus satyrus, is an astronomer, using its vision of the entire Milky Way to help it navigate at night. Without a view of our galaxy in the sky, beetles would wander and seem lost in experiments that show that dung beetles use astronomy for navigation. [url]
- Goniurellia tridens is a fruit fly that evolved very detailed images of ants on its wings. When this fly flaps its wings, it confuses its predators — but some observers say the images are of spiders (not ants) and trick spiders into thinking about mating (not eating). [url]

“When this fly flaps its wings, it confuses its predators — but some observers say the images are of spiders (not ants) and trick spiders into thinking about mating (not eating).” (Boldface added.)
The idea that these markings must be images of ants or images of spiders (but not both) is a silly human idea. They are markings that tend to reduce the fly’s danger of being eaten. They were not put there for any purpose, nor in any deliberate imitation of ants or spiders. How much they beguile spiders is testable, how much they confuse other predators is testable, but there is absolutely no reason why they can’t do both. (And in a sense, the spiders and other predators collaborated on the design.)

“They were not put there for any purpose”. And you know this how?

Because I get my knowledge of biology from science, not folklore.

Just remember you said that with the next Piltdown or Java Man they pull on you.

Hey, you know who discovered that they were hoaxes? Scientists. You see, while errors and frauds appear in literally every corner of human endeavor and understanding, the process of science does a fantastic job of correcting for that.
Re: Re: Re: painting without a painter
“They were not put there for any purpose”. How has science conclusively proven that?

I argue with creationists once a year. I don’t want to use it up on the seventh of January.
Re: Re: painting without a painter
Beta is correct. It’s an annoying thing the press does when reporting on All Things Evolutionary: asking “why did that evolve?” as if there was some kind of thought put into the process. There was not.
We need nature-rays just so we can run around and shoot people screaming “GET SOME NATURE IN YOU, BOY.”

With that out of the way… I remember reading some really cool & creepy articles about various insects on Cracked. For example, I seem to recall that the biggest ant colony covers several continents. (A colony being defined here as ants working together instead of fighting or ignoring each other. Maybe we could just call it a nation instead.)
That does it I’m getting tattoos of dragonfly’s, In hope it’ll keep the mosquito’s away.
