Charles Darwin tried to give a more scientific explanation. Since it's written in an old-fashioned style, it may be hard to understand:
"...the individuals which were the highest browsers and were able, during [droughts], to reach even an inch or two above the others, will often have been preserved.... By this process long-continued... combined no doubt in a most important manner with the inherited effects of increased use of parts, it seems to me almost certain that any ordinary hoofed quadruped might be converted into a giraffe."
1. Has anyone found fossils of short-necked giraffe herds that prove an earlier stage of evolution?
Answer: No.

Danger Will Robinson.
If we evolve into creatures capable for star travel we will survive. If not, we won't. Simple. Individualy, we all die anyway. Societies and cultures come and go. Mankind as a species will continue or it won't.
I am a gardener. I tend my portion of this Earth. My plants sustain me. My animals feed me. I help my neighbor and he helps me. We get by, or we don't. I am satisfied by my lot. The passage of years brings this wisdom.
Evolution to me is art. Art in the structure of DNA. Art in the flow of the solar wind. Art in the music of the spheres. Art in the love of a mother for its offspring. Art in the love of people for others. Art is seeing, feeling, being, wondering, disbelieving, questioning, learning......evolution.

current moon phaseAt a certain point the universe has expanded so much that matter can't really find other matter and yeah, maybe it's not absolute zero, but for all practical purposes it is.ygmir wrote:would that not happen only when everything attains "absolute zero"?
or, can anything ever attain said state?

But, if the universe expands to the extent that everything is evenly spaced and nothing can act upon anything else and that would be a singularity, and since a sigularity can only occur "once" (else it wouldn't be a singularity). And also since the universe supposedly was created from a singularity (immediately prior to the BANG) wouldn't that mean that the end of the universe would also be the beginning? ie., a closed-loop? And if so, since we'd have to assume that the laws of physics don't change; if the universe "reset" and went BANG again wouldn't every particle move in the exact same way, so at some point the the future (which wouldn't really be the future, it would be some point in the now; wouldn't I be sitting here typing this exact same message?

Which then would mean that ultimately evolution leads us no where other than right back to where we started?![]()

If humanity began in Africa or Africa proxy we were all one color and as we moved from the equator (just hot regions in general) humans got lighter, hair began to cover our bodies (warmth), our vessels became smaller and deeper within our bodies (High Altitude), Noses became narrower (warm cold air). Our bodies adapt to surroundings, it's a form of evolution.
Personally I feel that the over stimulation of our youth is a trigger of Autism and it may possibly be something that will prove to be an evolution of assistance, once harnessed. Same with cancer, it is a genetic mutation which kills people at the moment, but who is to say that we will not be able to harness the reproductive abilities of cancer to trigger limb regeneration.

a friend of mine is a cancer researcher dealing with pancreatic cancer, and, with some success........
he feels his angle is that cancer cells become "immortal", not knowing when their life span is over......and so keep reproducing but not dying.......and has had success treating them, as such.
well.
what if cancer is the beginning of a longer life span, or, as you suggest, regeneration, advance?
perhaps, when it mutates a certain way, it'll provide that. Perhaps, it'll take couples, carrying a gene that now causes/allows cancer, to have children and with genes from both parents, will develop a positive outcome..........IIRC there are other "diseases" that, when both parents carry the gene, are actually beneficial. Is not sickle cell anemia, like that?
