Evolution, religion, and ignorance.

[Esquilax]

Any extra part of any creature that is attached has to have full and complete use immediately.

Why? Because you said so?

Partial parts have no function, and usually disappear in the next generation.

Your little toe bears no weight, and has failed to do so for the entirety of human history; it has no function, and yet it has existed for generation after generation. Are you just making this up as you go along?

A complete addition requires the mutation to be fully functional which takes trillions of connections to be made throughout the integrity of the creature. Remember, that part has to grow, heal, reproduce, function with nerves or other contacts, and provide for some useful function for the benefit of the animal or that creature can not even use the additional part.

Or, that part could be used for something else, and over time it grows in complexity and gains new functions. The eye, for example, began as a patch of light sensitive cells. A very simple mutation, a cupping form around those cells, introduced the ability to ascertain the direction of that light. The cup begins to deepen, offering more directionality, and the other parts, the optic nerve, the retina, the eyeball itself, all evolved in later, building complexity based around the idea that visual awareness confers a survival advantage. This is a demonstrated scientific fact, and your only response has been to demand, like a petulant child, that the only way this could work is if the new features just popped into place all at once, despite that fact that an alternate method has been offered to you, and confirmed through science.

This is not a simple game of just sticking on extra parts to see if it might work.

Yes, because evolution doesn't work like fucking Spore!

Those trillions of connections have to be perfect, all at once, the first time or the part won't work.

Why? Because you say so? What's your education in biology, that you make this claim so confidently?

That's your catch! Besides, take a close look at all of the animals in nature. most do not show anything extra, dangling off for some future experimental use.

Vestigial organs are all over the place. Humans have several. Some snakes have little useless legs. Emus have little claws on their stubby, useless wings. Dogs have pointless dewclaws. Giraffes have a couple extra meters of useless Laryngeal nerve, at least.

And that's just playing by the rules you've set up, even though those rules are wrong anyway. You are so fractally incorrect that the conclusions you made using incomplete premises don't even work out the way you wanted them to.

These questions I ask are really simple to answer. All you have to do is try another way of seeing things.

"If only you would be more open minded to the fact that I am absolutely correct, while I ignore everything you say."

Fuck off, dirtbag.
