Chicken or egg? - organiSIM.com answers

First we'll look at a riddle (from http://www.creativepuzzels.nl/spel/speel1/puzzel17-2.htm#q7 , Rainy Day Riddles, riddle #2):

• fast growing plant
• grows at a factor of 2
• arbitrary specific day
• pond is filled
• what point is pond 1/2 filled? (related to point #2)

As I understand it, evolution involves tiny, tiny changes between one generation and the next. These changes are not designed, they are random, accidental and many.

Look at your family tree - how far can you trace it back? 3? 4 generations?

There are lots of variations involved - think of all your rellies - there are lots of them? They all look diferent enough? (apart from the twins obviously). So think of yourself as the ideal design as an end product. How many parents are involved? - this would give your line of descent. Also (and important), how many aunts, uncles, great-aunts, great-uncles and so on are involved? - This would demonstrate a lot of genetic missed targets - in only a few generations. Extrapolate this back and you begin to get the idea - all this variation to get to the one ideal. Now this is not quite how it works, but the numbers are an idea.

The process i'm trying to explain is that the end result is not designed & that evolution through natural selection is a process of continual improvement by tiny differences.

we get back to the chicken and egg thang: what came first? the egg! what laid the egg? something very very very very very much like a chicken but just not quite - the tiniest difference between what a chicken is and something that is not a chicken. This is where the pond riddle comes in. The generation before, just a single generation, such a small difference can mean such a significant one.

so... evolution?
