I am fascinated by the sometimes startling behaviour of insects.
These little (mostly) creatures create some major evolutionary nightmares. We won't go into metamorphosis and evolution's total inability to account for the transition fro egg to magnificent mature adults (as in the butterflies) - but this time I choose another of those facts which are as inexplicable today as they were in Darwin's day.
The Termites.
I will confine myself to only one of their incredible features: their digestion.
Here's an extract from an article:
http://www.desertmuseum.org/books/nhsd_termites.html
Cellulose is a poly-saccharide, that is, a large number of sugar molecules linked together by tight chemical bonds to form a very long, strong chain.
Cellulose is the substance that gives plants their structure and is the most abundant organic compound in the world.
Wood is mostly cellulose, and so are cotton and all paper products. In the Sonoran Desert, trees, shrubs, grasses, and cactus skeletons are the primary source of cellulose, which represents more than half of all the organic material produced by photosynthesis.
Cellulose is durable because it is a physically strong material resistant to mechanical breakdown, but more important, very few organisms produce enzymes that can chemically break it down.
[Termites, however, live on cellulose, and in fact, survive extremely well. How do they manage to do this marvellous thing, if they couldn't digest cellulose? Here's the answer... marvellous as it really is]
Among those that do produce the cellulose break-down enzyme cellulase are fungi and tiny animals called protozoans.
Termites do not produce cellulase, but all termites contain protozoans in their guts in a mutually beneficial relationship known as mutualism.
Termites grind up the cellulose mechanically by biting off bits and chewing them up; then the protozoans in their guts break down the chewed mass into sugars, which are readily absorbed through the termites’ guts.
[From that, you can see that the protozoans can't chew up the wood. They just aren't big enough to do so - so the termites do the heavy stuff.
[The termites, having done the big job, now depend entirely on the little guys to complete the digestive process. If they weren't there, the cellulose would simply pass straight through the gut and out the other end.
[But they ARE there, and so the termites survive, and so do the protozoans. Because BOTH organisms are mutually benefited. the arrangement is called mutualism.
[The evolutionary nightmares have begun.
Assume a proto-termite who has no protozoans in its gut. He chews the wood till he's blue in the face - and starves to death, because the wood just goes straight through him. No benefit whatever. Death and extinction of the species now follows as night follows day.
How did the relationship 'evolve' by little steps? Answer: it didn't, and couldn't. Without the protozoa, the termites are dead. Without the termites, the protozoa are exposed and would probably also perish.
[BOTH HAD TO APPEAR TOGETHER. NO EVOLUTION IS POSSIBLE. THE FIRST TERMITE HAD THE PROTOZOA IN ITS GUT AND SO COULD LIVE OFF THE WOOD.
IF IT DIDN'T LIVE OFF THE WOOD IN THE FIRST PLACE, THEN WHY DID IT START DOING SO?]
Both the termites and their protozoans share in the nutritional benefit of these released sugars.
[SO THE PROTOZOA HAD A HOME, AND THE TERMITE HAD A VERY USEFUL SERVANT - AND BOTH LIVED HAPPILY EVER AFTER - TOGETHER.
Now notice a demonstration of pure intelligence.
But wait a minute, does a termite have a brain able to figure out the mysteries of bacterial and protozoal inoculation? How did this happen...?]
Newly hatched termites are first inoculated with these indispensable protozoans by eating the feces of their older brothers and sisters.
So termite no.1 had protozoa in it's feces. Or it couldn't pass them on to its descendants.So how did the protozoa get there?
Answer, they were placed there by the Creator. No evolution possible or necessary.
Another major flop - because there are 2.600 species known, and estimated there is a total of 4,000 species in all. That's a pretty big number! Not to mention the fact that there are zillions of individual termites!
Another 4000 species whose existence and survival cannot be accounted for by evolution!
