Quote:Beetles have wings that are covered by a hard horny shell that connects from a cephalothoracic hinge.(If you look at a beetle , it looks like a little tank with its head and wings covered by protective armor, called an ELYTRA). The elytra is opened and the two sets of wings then allow the beetle to take off. Look at a ladybug and see how before she takes off, she opens her little elytra and like with flaps extended, takes off
However, in many island beetles , the elytra is fused so the beetle cannot fly at all . The wings are perfectly formed beneath the elytra but unless someone would cut the elytra sagitally, the beetle remains on land as a hiker. Now, is this an adaptation to a predatorless island? Is it an irreducible complexity, or what/
Yes- it's an IR. (I used that acronym, partly because I like acronyms and partly to save threaders who don't wish to type two long words out the botheration of making it harder to concentrate on where the sentence is going.
Like we use NATO. If somebody starts a conversation -{heaven forbid}- "The North Atlantic Teaty Organisation should be blah blah blah" we would glaze over.
A sort of a little tweak in the evolution of your new thread which I know, and perhaps even some viewers do, is bound to be a load of fossilised bullshit. Parthenon zone circa 2 1/2 grand ones BC. (BlessHis Cottonsocks). )
What it is is that there's a certain group of people (often quite loosely connected) who have invested their whole life's study in the aspects of life you are concerning yourself with and for which they need a megaphone to spray this knowledge in order to facilitate an invidious comparison with us mere mortals, and that area of study is slipping down the ratings. The audience is diminishing. Maybe the grants too.
As Bob said-" Inside the museums infinity goes up on trial".
I've seen him sing it as if the verdict is guilty of the despicable crime of BORING EVERYBODY STIFF.
Do you know that verse fm? It really is very good. That doesn't look back.
It's an attempt to talk your position in society up to the level you feel you deserve and starting another thread is a sign that it hasn't been going too well lately what with one thing and another.
Everybody knows that beetles look nothing "like a little tank with its head and wings covered by protective armor,". Not a scorrick of similarity unless you get down to molecules. And if you get down to molecules they look like MT Everest. The armour is not that protective. You must have stamped on a few in your time.
Can't you see that your second paragraph is based on what you think are beneficial adaptations.
It must have suited those beetles which only had half formed elytra to so do. Redundant wings. Like your car is redundant when you're nodding in the rocking chair listening to a talk by Professor Dawkins.
Isn't the survival of those beetles proof that they are successfully adapted
to the environment they are in. How do you know anything about that. Just because you think flying is superior to not doing has nothing to do with those beetles. I've seen lots of ladybirds take off and it looks pretty hard work. Evolution avoids work. It does the least necessary.
Why are ladybirds so brightly coloured. Most of them must get eaten up otherwise they would be 1000 ft deep by now. That would seem a dysfunctional adaptation unless one might liken it to the half formed elytra
and see it as some form of redundancies buried deep within the IR.
Elytra is your word. The beetles don't know anything about that either.
