    I was just wondering what were the unknowns in modern science

    So far all I can think of is:

    - Which interpretation of the double-slit experiment is true
    - The hard problem of consciousness and how consciousness is generated
    - If multiple universes (of any type) exist or not
    - abiogenesis
    - The origin of the universe

    I know there are probably innumerable, countless unknowns, but this is all I can think of

    What are the other unknowns in modern science I'm missing? I was just wondering...

    Did anatomically modern Homo sapiens evolve in Africa and then migrate out around 50,000 years ago, completely replacing H. erectus and H. neanderthalensis, or did they evolve all over the world from H. erectus, maintaining regional continuity of characters present in places like Java, China, the Balkans, Europe, etc.?

    ...and ...excuse me while I pop my knuckles... what ever did happen to neanderthals?

    Also

    -How did humans suddenly appear in Chile?
    -Where were major lakes, seas, and shorelines over 8,000 years ago?
    -Is there life in our solar system?
    -Why is chirality biased?
    -What is gravity?
    -Why does time point one way?
    -Why does a human share half its genes with a banana?
    -

    So far, they appear to have been replaced or out-competed by anatomically modern humans. The replacement might have been through out-right elimination/extermination that happens when two competing species occupy the same niche and one is better suited, or it may have been assimilation (depending on how distant H. neanderthalensis was from H. sapiens).

    Then, again, if Wolpoff and others are right, there was no H. neanderthalensis (or H. erectus for that matter), just different expressions of H. sapiens. And they weren't replaced or assimilated at all but were there all along and evolved in multiple regions maintaining regional continuity of physical traits (like shoveled incisors of Asians).

    -How did humans suddenly appear in Chile?
    The answer to this might depend upon how you define "sudden." I think you're probably using the definition that many use, which is sudden from our perspective, looking at the fossil and material records. However, it's likely that there were migrations earlier than our earliest evidences, though probably not much more than a thousand or few thousand years. There are good models for human migration and dispersal from Beringia at around 14,000 to 11,000 years ago in multiple dispersals that do a good job of accounting for the presence of earliest anatomically modern humans in Chile.

    Still, much of what we surmise about dispersal and migration is based on models, which produce some expectations and predictions. So far, these have been born out.

    -Where were major lakes, seas, and shorelines over 8,000 years ago?
    We have good evidence for most of the Pleistocene shorelines and this is growing each year. It's dependent only on the ability of researchers to get underwater and examine ancient shorelines, dating corals, shells, wood, etc. There were some recent developments in the Great Lakes that showed ancient shorelines and human habitation sites that date back to about 11,000 years (or perhaps it was 8,000 -I'm going off of memory). There are very good data of Paleoshorelines off the coasts of Africa and the Arabian Peninsula that are well dated and recorded -artifacts include Achuelean hand axes, and the like. Even some Oldowan Industry (Mode I) lithics if I remember correctly. These shorelines have been dated using mollusk shells and other biostratigraphic techniques as well as carbon dating of coral. There are shorelines in the Black Sea that are well documented by using dendrochronology and mollusk studies. The same for shorelines in the Mediterranean. Plus, these shorelines are often predicted to be at certain depths due to mathematical calculations based on known water levels at given depths.

    -Is there life in our solar system?
    Yes. We have evidence for it already.

    You cant say that because it is not enough evidence.

    For some reason I don't see teachers and professors teaching that there is extraterrestrial life. Maybe they do now but not that I know of.

    We are all different and think differently. I think there are other universes that god created with different laws of science out there that we wont ever be able to reach because our brain is not smart enough. Our brain has limits just like everything else.

    well i think the science should have to explain :

    -Is there life in our solar system?
    -Why is chirality biased?
    -What is gravity?
    -Why does time point one way?

    importantly ...

    You shouldn't be so sure about life in our solar system. Our solar system is very big compared to us and our friend technology.


    It will take a couple thousand years to reach the second nearest star. we only seen pictures of our planets but it is not easy to land on them and actually have robots look. You see if earth was one degree off we would either freeze, Burn, or crash into something. Lets hope that doesn't happen soon.

    Heh.


    Regarding lakes & shorelines during deglaciation, I was thinking of central Asia. That drying belt including Caspian, Aral, and Balkhash, was fed by meltwater. The water couldn't flow north because ice sheet blocked the way. Add to that a puzzle of local glacier holdouts, and land variously depressed now springing up, you have a riddle where the only certainty is water, lots of it.

    Same problem with meltwater in Canada. A heavy wall of ice blocked the Mackenzie river basin, which more than spans the human corridor many people really want to exist. Unless frozen, the corridor would fill with water.

    Hmm.. now that I look at just how long and narrow that corridor is reckoned to have been, I wonder if it wasn't subglacial river? I mean a water channel beneath the ice sheet. And like any river it would transport and deposit organic debris, which we'd later carbon date and assume must have grown/lived in situ?

    There is life in our solar system and I have evidence for it. Period. And its taught in even the most backward, creationist-deluded, private christian schools.

    My goodness, what a nice, polite comment on 80% of the American People and their faith. Reminds me very much of the scientific communities faith in their beliefs, which have been changing over the years and with no less mention of the changes...

    Extraterrestrial life is defined as life which does not originate from planet Earth.
    Personally, I believe there may be a good deal of primitive life forms, possibly some reasonably complex (opposed to micro), in this solar system, however I am also unaware of any proof.


    RAK; Think their playing word games with you, for not distinguishing earth's life from your initial statements, at least I hope so. We are in this solar system.

    80% of Americans are creationists?

    In 2007 (poll conducted just over 2 years ago), it was closer to 66%, but yeah... Pretty frakkin disturbing and backward all the same.


    http://www.gallup.com/poll/21814/evo...nt-design.aspx
    Creationism, that is, the idea that God created human beings pretty much in their present form at one time within the last 10,000 years:

    Definitely True: 39%
    Probably True: 27%
    Probably False: 16%
    Definitely False: 15%
    No Opinion: 3%

    Fortunately, a study conducted just 3 days ago suggests this trend is shifting for the better:


    http://rawstory.com/2009/12/29-ameri...gion-out-date/
    A Gallup poll of Americans' attitudes towards religion released on Christmas Eve found significant recent increases in those responding either that they have no religious preference, that religion is not very important in their lives, or that they believe religion "is largely old-fashioned or out of date."

    Only 78% of Americans now identify as Christian, while 22% describe their religious preference as either "other" or "none."

    Most of these changes have occurred since 2000 and represent the first significant shift since a sharp decline in religious adherence during the 1970s. Over the last nine years, the number with no religious preference has grown from a level of around 8% to 13%. The number for whom religion is not very important has climbed from just over 10% to 19%. And the number who believe religion is out of date and has no answers for today's problems has jumped from slightly more than 20% to 29%.

    Here's the actual study/poll and it's results: http://www.gallup.com/poll/124793/Th...Christian.aspx

    Oh for the love of... No one said "extraterrestrial" life, there is no evidence for that. There is life in this solar system, ON THIS PLANET... How do we know? What's the evidence? The life on planet Earth... That we, ourselves, are a part of...

    Really, how could you miss the point Skin made when referencing the fact that WE are alive and having a discussion?

    Read Jackson's post. He meant on earth. Aside from this though, there is evidence that might suggest life elsewhere, but nothing yet that proves it outright.

    KALSTER, that was an observation, not an argument, however to explain;

    80% of the US people or more, SAY they are Christan or for the grace of some God they are here. What this breaks down to in individual concepts, to my knowledge has not been determined (broke down), but an awful lot of otherwise intelligent people IMO, actually believe in the VERSION, of a 6k year old existence, mankind to the Universe (all things).

    No doubt SkinWalker and I would agree, if the topic was evolution v creationism, as I do agree with his other post, this thread, but I also believe science has been flawed by religious teachings and humans natural tendency to invoke/involve/evolve faith on all matters, science no exception. That is, faith is a basis in accepting any premise, nothing necessarily wrong with this and most US People accept the religious understanding.

    This Christmas, 78% of Americans Identify as Christian
    12/24/2009

    http://www.gallup.com/poll/124793/th...christian.aspx

    inow; Your poll is truly disturbing, showing a lack of education and the power of Religion in the US, two thirds of the Christians believing in a 10k year old planet, probable or definite, but it does NOT surprise me...

    More disturbing is the obvious and willful flaw of the poll. This Christmas, 78% of Americans Identify as Christian Like, "Merry Christmas! This Christmas Season we traditionally conduct a survey, the results to be released on Christmas Eve, so we are calling you a week before Christmas..."

    What people say in a poll, is not for me to judge, but during certain times of the year or during hard times, most folks need something to lean on. Whether it's religion, their family/friends, themselves or even government, I'd like to think it helps.

    I however agree with you, the poll could not have been accurate for percentages, this time of year and during some really hard times for most of us. While, I cannot believe in religion as practiced or preached, if nothing else for those that have passed before me and religious, during my very long life, it's my sincere desire, I AM WRONG.
