In nature, primes are the key to the survival of a strange species of insect. The prime-number cicadas hide in the ground for 17 years, then emerge en masse from the earth into the forest. They sing loudly, eat, have sex, lay eggs and then die after six weeks of intensive partying. The forest goes quiet again for 17 years. But why did the cicadas choose 17, a prime number, for their hibernation? Scientists believe there is a predator that likes to crash their party and also emerges periodically after a certain number of years. The cicadas found that by choosing a prime-number cycle for their party, they could keep out of step of the predator more often than if they'd chosen a non-prime such as 15. For the cicadas, the primes aren't just some abstract curiosity, but the secret to their survival.

Uuummmmmm because it stinks so awfully, and it needs 6 years to summon enough courage to bloom? []

It's shy

Coz it's huge: not enough resources to produce an organ that big every year.If you're interested in weird reproductive cycles have a look a the prime number cicadas ...QuoteIn nature, primes are the key to the survival of a strange species of insect.

Now wangle your way out of that one!

HOW DID THE GENETIC PROGRAM EVER GET CONSTRUCTED AND INSERTED INTO THE GENOME?Once it's in, then natural selection can act. I agree with that. But that IS NOT THE QUESTION. Now stop fudging the issue and admit that there's no explanation other than divine origination.

3 The created 'kinds' (I read our modern taxon 'families' for 'kinds') had considerable but limited amounts of variability built in, as we see today.

There would have been a wide genetic variation in the period of the life cycle of the cicadas, e.g. 1,2,3,4 ... years,but there is natural selection for the cycle where there is least predation, this will be a prime number of years.Those cicadas reproducing on other periods will be predated more and are less likely to live and reproduce and pass on their (genetic) non-prime clock. So over time the bulk of this species has its life cycle tuned to a prime number of years.
