Can natural selection select for future needs of a species?
Futuyma: No, because natural selection is not like Mother Nature watching over us. Since natural selection is totally an impersonal process that is nothing more than a difference, generation by generation, in the reproductive success of one genome over another, there’s no way that it can look forward to the future or guard against the possibility of extinction. What individuals have right now that gives them superior adaptation may lead to disaster tomorrow.
Could you give us an example of natural selection at work in the recent past?
Futuyma: There are so many examples of that! One example is the apple maggot fly. About 100 years ago it started to become a serious pest of apple orchards in New England and New York State. It’s now a threat throughout most of northern United States. It originally fed just on hawthorn fruits, but then it adapted to apple and it’s become a serious threat to the industry. That is a genetic change propagated by natural selection.
Perhaps much more crucial is an issue that agriculture has to deal with all the time: the evolution in hundreds of species of insects of resistance to various chemical insecticides. The insects then become more and more difficult to control.
Closer to home, and more serious, is the single greatest crisis in medicine: antibiotic resistance. The fact is that enormous numbers of the most dangerous bacteria and viruses have evolved to be resistant to the antibiotics or other drugs that used to be effective against them. An obvious example is the HIV virus, which, as we know, is capable of rapidly evolving resistance to drugs that once were effective against it.
So we agree that mutations can't be random if environmental factors also directly affect the genome. And I am not talking about the field mice. It can be assumed that is the reason for brown and black field mice but it doesn't answer for why there are albino mice.
I'm keeping the goal post at "please provide evidence for your claim". So I ask, please rebut any of the scientific evidence in the articles themselves.

Whatever you say, warminindy will just twist your words. Look at everyone of her replies. None of them have anything to do with what the poster wrote. This is worse than mere trolling. This is compulsive misrepresentation of the argument. Whatever you try to explain will be twisted and thrown back at you until you throw your hands up in disgust. . This is willful ignorance at it's worse.
This thread is 23 pages deep and she hasn't made a sensible post yet. She not only doesn't understand what you are saying, but she doesn't understand what she is saying either. This is a nightmare for the world as a whole.

1: Does every individual of any group of species mutate at the same rate as all members?
2: If the definition of species is "members of a group who are capable of interbreeding" and species first began in a singular biome, then if there is another biome in which a species population resides, did the species in the biomes mutate at the same rate?

Where's your the data that says Ata wasnt capable of breeding with other humans? There is absolutely nothing that indicates anything other than human DNA and only a few decades old at that. The Ata remains are no less human than someone born with Downs Syndrome or any other genetic anomaly.
Why doesn't it follow the rules to call it a human? Wat exactly is anomalous about this?

I know he is human, but would you call him Anatomically Modern Human? He has less ribs, and obviously he died too young to interbreed. Would he be Homo Sapien Sapien?
Ata was 6-8 years of age, fully formed, and yes as a human. But as Homo Sapien? Why do I ask this? Because of Homo Florienses
And what makes him anomalous is the fact that he has fewer ribs. If he were an aborted fetus, that was done by a sharp object, there should be forensic evidence of metal cuts on the skull. That hasn't been offered yet. If it is possible that he evolved from a non Homo Sapien, but still human, then perhaps AMH has not lost traits of archaic humans.
He clearly is not phenotypically AMH with the lack of the two ribs found in all AMH.
But the issue I have with speciations of human groups, they were based on phenotypical features, such as wrist bones.
And here is a reason I believe that Neanderthal had stockier bones, in their environment they were exposed to higher amounts of strontium and metals from the glacier run off. Even in my community in Ohio, we were exposed to this in our ground water, we all drank from wells that were not treated. We didn't have water filtration systems from those underground streams, but high amounts of Strontium was present.
One of the prevailing features of people in my area is that we do exhibit stronger bones, remarked by physicians. If a group of people had access to vast river systems that were glaciated water with high metallic content, then what would happen in 20 generations if they all drank the same water, before it went so far into the ground? Would there be phenotypical expressions in the genome?
Strontium in groundwater and I would imagine that if they were eating a lot of meat or fish, they probably were ingesting high amounts of calcium as well.
The county I am from is the fifth county down, on the left side (Indiana) and we had a carbonate well. I would have been the fourth generation on the property, but it is a common knowledge that my community and surrounding county was well-known for stronger teeth, when I was 8 years-old, the US Army came to my school to test the teeth of the boys, because it was at that time an unusual phenomenon.
Now imagine a group of people that have lived in an area for 20 generations, drinking water saturated with higher amounts of metals, because of glacier run offs, then what would the effects be?
Evolution is a lie spread by Satan to provide an alternative to the truth for people to turn away from God.

The evidence does not include a time stamp tag on the fossils which were buried in the flood.

How could it when there was no global flood. But if hooked on phonics had worked for you, there would at least be an awareness that the flood has been discussed already. Or are you just jumping in to the tail end of a lengthy thread to impart your delluvian wisdom without having gone through the actual thread first? If that's the case I'll take my chances with Satan. At least he engages in due diligence.
But all of that doesn't relate to the thread, just my musing that people have forgotten that it will not destroy them if they actually study what the other side believes. Non-believers and believers alike are sometimes afraid that if they give in, it means they will lose something fundamental about themselves. No one wants to be perceived as stupid, so that's why it is easy to throw the accusation onto someone else.
All the words I have typed here are symbols of written communication, but the result of algorithms going on behind the scenes. Yet, you understand my language and communication because of the symbols. And that's how some believers accept God, because of what is going on behind the scenes, and all we see is communicated in a language represented by symbols.

Oh but those paintings and sculptures are conveying a message, it is communication. Didn't you take Art History? Or was that someone else?
What is the artist telling us? Visual path, focal point, balance, harmony and asymmetry all guide you into interpreting what you see. Film is 72 frames per second of still images, but through persistence of vision, you believe that what you are seeing is moving.
