So explain to me how the first creatures who "needed" very specific features in order to survive survived? They were still adapting to the planet. So how do birds evolve to grow longer beaks? How does genetics "know" that the bird needs a longer beak in order to survive? And apparently the original beaks were just fine because the species continued to live on to this day. Evolution claims that the original giraffes did not have long necks. How then did they survive without the proper features needed to survive? As anything evolves to protect itself from predators and consume food easier, so does everything else. The giraffe, according to the theory of evolution (which has definitely not in any way been proven, why do we have ape-like creatures from which we "evolved" from?), kept stretching its neck towards a tall tree where it needed to feed from. How did the original giraffes feed, and when they did, didn't the trees in which they fed on "evolve" to form some sort of defense? Anyways, over millions and millions of years the giraffes bred and bred until finally their necks got longer and longer. What were they feeding on for millions of years if they had been reaching for the top of a certain tree for all of those years?
Ask yourself, if someone has their arm chopped off, do they lose the ability to bear children who have two arms? Not at all, the arms won't even be deformed one bit, one would be a fool to think so. Evolution deals with every organism learning to "deal with their surroundings". If the water fowl developed clear vision in water over millions of years of "trying", how did they survive up to this day, and if they survived then, what would be the use of being able to see in water? Hows does genetics determine whether to give them this ability, and not something else "accidentally"?
There are many, many flaws in the argument of evolution--up next: "Survival of the Fittest" (this is more of a self-reminder for the next topic I want to talk about).
Alright, I can clearly see you don't know much about evolution. I think it would help if I explained the gist of it:
As everyone knows, organisms have DNA in their bodies, and this DNA is passed on to children. Every so often however, there is a mutation (a 'mistake' in the copying process). Most mutations are harmless and don't make any noticeable difference, while a few of them are bad, and a few of them are good. A good mutation can give that organism the edge over its competitors, which makes it more likely that that particularly will survive to reproduce and pass on the mutation (for example, the giraffe with a longer neck can reach food in trees which its competitors can't reach, so it's got more food to itself). This is natural selection, or as you might call it, 'survival of the fittest' (although I don't particularly like the term- any organism which lives long enough to reproduce is basically 'fit').
So no, evolution doesn't 'know' what an organism needs to survive, nor does it 'know' anything- it's just a process. Organisms gain their features at random, and those features that aid survival are more likely to be passed on to their children.
I know how some people like to talk about the intelligent design hypothesis, saying how some features are supposedly "too complex" to have evolved (usually without any quantitative measure of 'complexity'), so I'm going to pre-empt it. Intelligent design is bad science made up by people who don't have a clue about genetics or biology. For example, let's take the old creationist favourite, the eye. It's certainly tempting to think something so complex could only have been designed, but consider this: some eyesight is better than no eyesight. The first eyes to have evolved would have been incredibly primitive, barely letting you see how bright it was. But that's still better than not being able to see at all. Over time, some organisms evolved more and more complex eyes, allowing for directional vision, better focus, colour vision, etc.
