This cat is perfectly camouflaged to hunt mice in a Canuckistanian hardware store.

I don't understand your point.
A genetic change may be advantageous, disadvantageous or neutral. You know this. A single alteration can produce a huge change or none. The significance doesn't necessarily correlate to the degree of alteration.

??? -- not following. Still not following. Insignificant changes may become significant with a change in environment, or with another genetic alteration that interacts with it.
Why can't genetic changes be "saved up," and what do you mean they're "disregarded?"

They do? Wouldn't deleterious changes be weeded out of the gene pool? Wouldn't advantageous changes be retained and spread?
Where are you coming up with this stuff?
Yes, there's junk DNA, but if it becomes deleterious it's eliminated.
If the text becomes unreadable the paper/organism's eliminated. Life's been happily reproducing for millions of years. It hasn't fizzled out from accumulated errors.

Yes, it was a logical extension of classical physics at the time, where a handful of simple immutable laws could account for all the sophistication of physics, given enough time and space to randomly bump around in.

And if you thought there may be hidden, underlying guiding forces, instructions required, to predetermine exactly how and when development occurred- you were not very smart- this was before subatomic physics and quantum mechanics of course.

You or I can sort through our pockets before doing laundry, throw out the trash and keep the loose change- not because it imparts any immediate advantage whatsoever, but because we are able to anticipate a future accumulated payoff, right?

'nature' cannot do this, it is quite happy to keep the candy wrapper and chuck the loose change away, the advantage must be immediate- enough to significantly improve the chances of survival and reproduction, otherwise no natural selection takes place.


This is where our intuitive anthropomorphism is liable to take over, and we allow nature the ability to actively retain very small advantages so that they might pay off over time- the cold hard math says otherwise, unless an immediate advantage is imparted, natural selection is no more likely to retain the insignificant advantage than an insignificant disadvantage- without anticipation, the 'nickel and the candy wrapper' have the same practical value

But genetics keeps both the trash and the nickel. There's a lot of "trash" DNA that appears to do nothing.
Even a gum wrapper can be potentially useful, in the right circumstances.

I just saw this on FaceBook.....


Just another accident of nature......you've got to be kidding!
It's called "evolution" through "adaptation" as organisms unconsciously, and sometimes even consciously, try to adapt to their environment. This is basic in biology.

The idea that a deity directly caused this adaptation is not basic to science or even religion any more than blaming God for miscarriages and earthquakes.
