Had some questions about evolution.
I know very, very little about this topic. Never took a class on it. (Why is for another thread.) That is probably why I still don't totally rule out the fact that a God could exist, but I've been doing some studying on this subject and I'm sorry in advance if some of these questions sound totally stupid. I litreally just a few minutes ago began looking at some youtube clips on it:
So we have all these different types of animals (humans included) and it took a few million years for all living creatures to evolve? Is this correct?
If that is correct, does that mean in...say....another million years we humans are going to look different and that animals may look different as well?
Does it ever stop? Meaning will we humans and animals ever settle into one form or are we going to forever be growing?
Are we humans going to get smarter? I am guessing yes because when we look back on our past, we probably see the way people lived as being cave manish compared to what we have today and if you study history, you clearly see as time goes by, things get better and better.
Final question: Do you think it's possible that a God of some sort is the one doing all this? Or is this just all happening on it's own? I don't mean the Christian God by the way. I think that's a man made concept, but could it be some type of higher power out there with some type of plan?
I know some believe that in a billon years, the world will blow up and maybe that is a good thing because if we keep growing and growing without someone to push the "stop" button, who knows what will happen.
It is an interesting idea: Some believe the world started with a big bang and maybe it will end with a big bang too. That right there does leave me open to the idea that a higher power or aliens or something out there is doing all this. It just seems too weird to be doing it to itself. Like maybe after this world blows up, another chapter for humankind will begin and ALL this right here will just erase.
....In fact, maybe that's already happened a few times. Maybe there was a whole other history of humankind before us and maybe this "God" is doing all this because he's trying to find a perfect society? Or it could just be happening on it's own. Like a giant clock that just goes around in circles over and over again.
Err....I am getting WAY too deep now. These are all pretty crazy thoughts. I'll shut up so the smart people can respond.

It appears to be closer to billions of years. See AtheistExtremist's post on the most recent find of truly ancient multicellular life.
Maybe, maybe not. It depends on the evolutionary pressures in the environment. When the environment changes, it may not change enough to push a particular species to change - or it may. We don't know this in advance.
Purge from your mind the idea that evolution means "growing", "improving", "higher on the ladder". The only thing that matters is whether you and your children survive to have grandchildren. This may involve losing some of the so-called "higher" evolutionary traits. A bacteria is evolved for the environment where it survives, no further evolution required.
Read Guns, Germs and Steel or watch the special. It's available on DVD so you can rent it. He thinks that civilized man is dumber than someone who is a hunter gatherer. Why? Because what we needed to survive in crowded communities is disease resistance, not intelligence. I still don't know if I agree with him, but I know plenty of stupid people, so he may have a point.
There are plenty of people who think there is some directive force behind all this. If so, s/he/it is a lousy engineer. And the plan sucks. 9 billion people? Inadequate food, water and medical care? This is a plan? A plan to increase misery, perhaps. I prefer to believe it is random because I want nothing to do with a god/s/dess who might have created this mess. Add that to the total lack of evidence for any such intervention, and there I am.

Well, we have fossils of stuff that was definitely alive 450 million years ago. Certainly stuff was alive before then, possibly as far back as 2,500 million years ago. The farther back we look, the harder the evidence is to interpret but apart from the scale, pretty much you have that down.
Well, there is no reason to assume that we are the final form of evolution. So if our descendants are still around in a million years, then there is no reason that we would be exactly as we are today.
Honestly though, a million years is not much time for large amounts of evolutionary change. Were it possible to go that far back in time, the ancestors of all of us would very probably be capable of holding a reasonable conversation with us (language barriers not withstanding). One would probably have to go back to around 3 million years ago to get to the point where we evolved the ability to do more than grunt at each other.
As I noted above, there is no reason to expect that evolution will eventually develop the perfect creature. A better question would be to ask “perfect for what situation?” Perhaps we will eventually build cities on Mars and the descendants of the first settlers will evolve in ways that are suited for that environment.
If, in a million years, we manage to settle other planets elsewhere in the galaxy, the people who colonize those worlds would adapt to whatever conditions they find locally.
Well sure. IQ testing is already showing this as a general trend. About 3 points of IQ per decade judging buy the results of the last hundred or so years.
Well, could aliens be messing with our genetics? I suppose that might be something worth at least looking into. However, if there are really powerful aliens messing with us, they have not done much to leave any evidence. For example, many genetic diseases have been fairly well studied and they all are natural in origin as far as anyone can tell.
Well, certainly the sun will run out of hydrogen fuel one day. As far as we can tell, big changes to the sun are probably not going to happen until about another 4 billion years, at which time, the surface of the earth will certainly become uninhabitable.
Well, now you are starting to get into cosmology, which is of course a different science. For what it is worth, we have plenty of evidence that the big bang really happened. Also, the most current evidence suggests that the expansion of the universe is accelerating, so probably no big crunch at the end so much as the universe just getting colder for at least the next several billion years.
One theory is based on observtion of how galaxies seem to move and it holds that the more distant ones will eventually recede from us so much that they will end up receding from us fasater than the speed of light and effectively no longer be part of the universe. The two dozen or so nearest galaxies appear to be falling in towards each other and they will possibly merge to become a single super galaxy.

My information is, that in future human physiology will remain pretty much the same, except of the build of eye. There will be minor change in eye construction, that will enlarge visible spectrum somewhat into infrared and ultraviolet. This will literally change our view of the world, because some things unseen and considered supernatural and unreal will become visible. This change will not occur by natural selection, but by esoteric kind of cyclical cosmic influence.
I think it is beginning, because I'm tired of the wasted time people here spend to clarify semantics, language, philosophies and logics. Can't they just do it subconsciously and understand each other, like we esotericists do?
As for other civilizations and humanities, I don't know if you mean previous universes (of which I know nothing) or previous batches of humanity, of which I know too much to do anything else than point a finger to a book. In particular, dr. Ernst Muldashev's book Ot kogo my proizoshl? (who's descendats are we) That guy is no esotericist, but scientist, inventor and optical surgeon.

Evolution is merely about slow and tiny changes over long periods of time. Evolution, is not about any biological life being the apex of life. Evolution is merely about getting to the point of making the next generation.
Bacteria and cockroaches outnumber humans, if that gives you any perspective.
It is most likely if we go by prior species that are now extinct, that humans will go extinct too, long before the sun expands and fries our planet. But life WILL continue as long as our planet can support it, even when humans go extinct.
