Which is why I don't believe human homo homo sapiens ever evolve. Mutate yes. Evolve nope.

The time scale you want is generations. There can be hundreds of mutations between each individual and it parents. A species that has multiple births in one generation can have thousands of chances at useful mutations (and bad mutations, and neutral mutations). It is random and as a Biologist you should understand that there is no guarantee that a useful mutation will arise at the right time (or ahead of time). Mutation 'rates' differ across species, across genders (human male sperm has a higher mutation rate than female eggs, for example), and in different regions of the DNA structure. On average, the human rate is about 64 mutations per generation (depending on exactly how it is measured).
There are about 130 million human babies born each year. So that is about 8.32 BILLION chances PER YEAR for a speciation level mutation in the human population alone. And that is one heck of a lot more than your 2,640 EST number.
Of course, for that speciation event to actually happen, it has to actually be present in one part of the population and give that population a survival advantage over another, isolated, population that does not have the mutation. Since there are no isolated populations on Earth for the last 100,000 years or so we just aren't going to see such an event until we start colonizing off planet.
Therefore, until we can colonizing off planet, there is no observable speciation evidence that present days human evolve.
Tibetan human are still classified as homosapiens despite their million years old variation.
And we would not see any mythical new species arise from human earth anytime in the future unless something radical change the entire earth, which it did billion years ago.
But then again who knows?

The data now gathered from some 100 years of mutation research in general and 70 years of mutation breeding in particular enable scientists to draw conclusions regarding the ability of mutations to produce new species. After examining the evidence, Wolf-Ekkehard Lönnig, a scientist from the Max Planck Institute for Plant Breeding Research in Germany, concluded: “Mutations cannot transform an original species [of plant or animal] into an entirely new one. This conclusion agrees with all the experiences and results of mutation research of the 20th century taken together as well as with the laws of probability.”
So, can mutations cause one species to evolve into a completely new kind of creature? The evidence answers no! Lönnig’s research has led him to the conclusion that “properly defined species have real boundaries that cannot be abolished or transgressed by accidental mutations.” (Mutation Breeding, Evolution, and the Law of Recurrent Variation, pp. 49, 50, 52, 54, 59, 64, and interview with Wolf-Ekkehard Lönnig.)

Again no, by saying "it just is! End of story", they are saying; "Do not question it because it is beyond questioning".
There really is no other way to spin it.

LOL dude. NOBODY IS ARGUING THAT. You specifically were talking about INTENDED PURPOSE, rather than evidence that supports evolution.
At least you admit you are spinning it.

Which “million years old variation” exactly are you referring to?

Right... aside from all of the other species in our genus that have existed, in many instances, contemporaneously both geographically and chronologically, for the last couple of million years.

Biologists, Anthropologists,Paleontologists and Geologists would be a good starting point

What is your point?
Are you saying: "Do not question intended purpose because it is beyond questioning"? If so, I will tell you the same thing. It is a faith based statement, no different that the Creationist saying "God did it, end of story".
None was provided to my inquiries. All that was offered was a statement based in faith.

So where is the ancestors of upright human aka Homo Erectus?
Where is human bones prior to 1.8 million years ago?

The co-existence of both Paleolithic and Neolithic ancestries on a genome-wide scale in the modern Tibetan gene pool.

Bones and blueprints of extinct non human species.

How about they start to explain the origin of life first?

My point is that you are misrepresenting the argument and straw manning Noiden. If you asked him, "How do you know evolution occurs, what is the evidence?" and he responded by saying, "Evolution just happens," then you would have a point because he'd be avoiding explaining the mechanisms and evidence supporting it and using a "God did it" type of response. But that's not what happened. You asked about evolution / life having a purpose, something that has zero supporting evidence, and he basically just said that it doesn't have a higher purpose. Stop exploiting semantics, it's dishonest.
Are you saying: "Do not question intended purpose because it is beyond questioning"? If so, I will tell you the same thing. It is a faith based statement, no different that the Creationist saying "God did it, end of story".
Nope, I'm saying there is no evidence of any intended purpose, and in fact there is conflicting evidence when you consider that genetic mutations are copy errors that affect random genes. When was the last time somebody intelligently designed something via completely random changes to the blue print?
None was provided to my inquiries. All that was offered was a statement based in faith.
How do you not grasp that YOUR ORIGINAL STATEMENT was faith based when you brought up a subjective unfalsifiable idea of a higher purpose. That which is asserted without evidence can be dismissed without evidence. Burden of proof is on you.

If there is not an end goal then what is the purpose of evolution?

Why must there be a purpose? To imply a purpose, implies a higher intelligence in the Universe. Science is not concerned with that. Evolution just is. End of story.
Serious questions:
If there is not an end goal then what is the purpose of evolution?
If there is not a purpose to evolution then why evolve at all?
"Life slowly changes in varying environments"- why, if there is no end goal, no purpose?

Here is your original post that was very clearly not asking for evidence, but asking about a PURPOSE
Yep. You are being dishonest.

Bigot: "a person who is intolerant toward those holding different opinions."
I can see other perspectives. You apparently cannot. I came to my beliefs through rational discourse.

It's all human nature.
Bias plays a huge role.
You only see dishonesty in "religious folks" because you are biased. Yet, you don't see it when someone puts their faith in science instead of God.
They act the same way as "religious folks", defending their faith.
I believe they attribute much more to science than what science actually claims most of the time.

Its not bias either... its the same old song and dance in all of these threads
Religious side makes a claim.... science debunks... religion ignores... repeats claim as if nothing was said... science repeats debunking and points to previous conversation where the same thing was said... religion ignores
Wash rinse and repeat
And around we go
God has nothing to do with this thread... as it has been stated over and over
