apes or no apes

ok this is gonna sound silly to most of you who reply here probably. but i was talking to someone at one point who had told me that humans didn't actually evolve from cro-magnon man. he drew i simple little timeline showing cro-magnon man's time periods and drew another line under it that started towards the very end of cro-man's line.
cro-magnun ----------------
human -------------->
it was similar to that...the point is that he said that there was a time when we both were around...but that humans didn't evolve here, we just appeared at a certain time, and soon after cro-magnun man became extinct...as if perhaps we were dispatched here from some 'other' place. can someone verify if this can possibly have any pinch of truth in it. i'm very much into the possibilities of extraterrestrial life...never thought about us being the aliens before.

Thread moved here from the Evolution forum.

Did he support this with data? Or just tell you it was true?It sounds made-up to me.

no he didn't support it, we were just at work one day discussing the possibilities of aliens and whatnot, it does sound made up, and i figured that if it had any possible truth then someone here may have heard something of it. i hold this man in high regard, which is the only reason it's still in my mind. unfortuanetely i'm no longer with the company and so rarely see him to see where he came up with this theory...oh, and that timeline shoulda looked a little more like this:Cro-magnun ------------
________________human ---------->his suggestiuon was that we evolved on a different planet a very very long time ago and were transported one way or another to here, all about as beleivable and evidence full as the bible. he said otehr things too, but i'm sure someone here either knows without question that we did evolve on this planet or didn't.[This message has been edited by Nexus, 01-30-2004]

I feel like he must have had no clue what he was speaking about, seeing as Cro-Magnons were identically modern humans. Now if it were Neanderthals he was talking about, there's probably some truth in there. They seem to have been a separate lineage from ours.

My Dad gets off on this tack every so often too. It seems to be very unlikely given that we have so very much in common with the living things of this planet and that we find fossils tying us here for near 200,000 years anyway.Until we have a sample of separate life we can't say for sure but it is not unreasonable that there can be other solutions to some of the mechanics of living. Life started and evolved elsewhere might be different in some very specific ways. For example, the base pair codes for amino acids might be different.Since we fit right in so well it doesn't seem reasonable to suggest we came from elsewhere. And, of course, there is no evidence for it at all.

Common sense isn't

i'm thinking that he may have meant that also...however i know he said cro-magnon, and i don't think he would confuse the 2, but either way, he's saying that we didn't evolve here. now if neandrathals were evolved from apes, and cro-magnon man comes from a different chain of evolution...what did they come from, or were they always just cro-magnun man since as far back as we can calculate?? i like the alternate ideas taht we just didn't evolve from apes...and furthermore taht we didn't evolve on this planet. i'd liek to hope that this is possible as long as no one can say straightly that we definetely evolved here from 'so and so'

Asking for "definitly" is too much. You will probably never get that.However, as noted if you want to try to support the alien source for us you have to explain all the data that ties us so tightly to this planet. If not you are just idlely speculating and it isn't going to be paid any attention to.

tomorrow i will make sure i contact him and find out wherever he gets this from. i'd do it now but it's best not to disturdb him at night, hopefully i can tell me something worth working with

Be sure to ask him why, if humans didn't evolve from Earth, do we possess a chromosome that is almost exactly the same as two ape chromosomes joined together.

I think that perhaps you are confusing Cro-magnon with Neandrathal.Neandrathal man was related to us but was a compleatly different kind of human. He lived along side us and at some point suffered mass extinction from unknown causes.It is belived that Cro-Magnon was a more successfull and agressive specieas and persecuted the Neandrathal to death. First genocide in human history perhapse.In any case, Cro-Magnon developed in the south in africa, and thrughout the millenia migrated across the middle east and into eurpe where they encounterd Neandrathal.The Neandrathals however, came from africa much much earlyer and had existed in the north for quite some time. Their phisical charactaristics point to a highly adapted creature for harsh climets and a hard life.

if this is true and it happened millions of years ago Id have to ask what kind of technology did they use to get here? I mean i wont believe that they floated off to earth. I guess NASA can benefit from this information.
Secondly, if they came from some where else they would of have died because their system(anatomy) wouldnt survive the conditions in this earth just as we wouldnt survive the conditions in any other planet or star in the universe. I guess plain logic reasoning makes that theory all wrong

there is a theory that millions of years ago mars had life...suggesting that we may be the descendants from that life. i beleive there are otehr planets out there which we could live and breath on, perhaps not very close to earth. and maybe very long ago before recorded history, there were humans, more intelligent and technologically advanced then we are now. i beleive it says in the bible "he shot lightning in a straight line at the golden calf and melted it" now being that the calf is gold, the electricity should have just ran through it and left it pure...also, lightning doesn't go in a straight line...what's teh only form of light that goes in a straight line and can melt metals??

I believe you are wrong on this point. This is the actual fate of the gold calf There are huge difficulties in crossing the vastness of space to another star system the greatest of which is the time necessary for crossing since there is a speed limit of 300,00 kilometers per second and even that is not attainable since as you approach to 30% of the speed of light space becomes abrasive since hydrogen atoms floating free in space become cosmic rays and the crew is subject to lethal radiation.This does not take into account the necessity of providing an enviroment diverse enough and large enough to keep the people travelling that distance from going mad.

damn, my theories suck =O
