If we couldn't be descended from the neanderthal, it seems clear enough there's nothing else we COULD have been descended from
This is just an argument from incredulity, and has no factual basis. There are plenty of other hominids in the family tree to show descent of both from a common anscestor, and the current trees shown on various websites (already given when this issue was raised before) do show both neanderthal and sapiens descending from Homo heidelbergensis. In post #13 ted\redwolf contiues this misconception with:
Basically, somebody who wanted to go on believing that modern man had evolved would have to come up with some new hominid, closer to us (than the neanderthal) in both time and morphology, to claim as a human ancestor. Which is not true. His whole argument is like saying because you can't be descended from your sister therefore you can't be descended from your mother. This is the pertinent section of the chart fromhttp://www.handprint.com/LS/ANC/evol.html Redwolf aka ted has yet to address this issue, even though it has been raised several times ... as in virtually every time he has presented his faulty argument. He also tries to muddy the argument with his pictures, and more faulty tree data. The oldest Homo sapiens sapiens skulls (160,000 years) look like the skull on the left (taken from UCBerkely News Release), the middle skull is Homo heidelbergensis (from Handprint webpage), while the skull on the right is Homo ergaster (KNM ER 3733, taken from Smithsonian website):
Note that I have assembled these pictures from the sources given and sized them so that the eybrow to jaw distance is comparable (I make no claim that these are absolute similar scales) so that the trend in shape can be easily seen. I see no problem with this lineage of ancestors. we are limited in our ability to understand by our ability to understand RebelAAmerican.Zen[Deist

Another possibility is that the interbred offspring were infertile - mules. This would allow a child or any individual specimen to have mixed DNA, but still no neander DNA in human genome.
Personally I have wondered if the temporal overlap between sapiens and neander is the root of the troll and ogre myths. This would shed some light on group interactions. I suppose one could do a search on the location origins of the myths and see if they match the population data to get some inference of validity, but it would be extremely difficult to make more than a hypothetical case. we are limited in our ability to understand by our ability to understand RebelAAmerican.Zen[Deist

I have extended the photo gallery from my previous message:
A Cro magnon skull specimen has been added at the front, while Homo habilis and Homo rudolfensis have been added at the end. I have also shown the "calibration" lines that I used to size the pictures in order to take out variation that could be from individual specimens and to show relative proportions. This is in answer to the claim by redwolf\ted that there is a major discontinuity in the family tree (Note that his "archaic" Homo sapiens is now considered Homo heidelbergensis and is shown as such here). Enjoy. ps - ted: the New Proposed Topics is the place to start new topics, see http://EvC Forum: HOW TO START A NEW TOPIC (as of 4/13/04) [This message has been edited RAZD, 05-03-2004] we are limited in our ability to understand by our ability to understand RebelAAmerican.Zen[Deist

can't you set the scanner to make a smaller copy?
I resize pictures in an html editor (frontpage is microsoft version, there is also firstpage {HTML Editor, Website Builder & Web Design Software} and other freewares) then copy the html code to use.

interesting -- did not know that: is that what causes some pages with pictures to take longer loading?
filed for future use on posting original pictures, but hard to avoid when using pictures from other sites ps - I notice that my e-mail reply notifications are not coming anymore? we are limited in our ability to understand by our ability to understand RebelAAmerican.Zen[Deist

I have changed my preferences to turn it off and then to turn it on again to see if that clears it. As yet I have not had a single message since the software change. I have only today verified that there have been replies (been busy).

in http://EvC Forum: Within Neandertal mt-DNA studies hybridization of fossil samples use as a probe -->EvC Forum: Within Neandertal mt-DNA studies hybridization of fossil samples use as a probe
Death_stranger asks: Within the reference to a hybridizatized Neandertal sequences entirely due to highly "technical reasons" is now deemed a controversial analyse means From a journal paper, it read: Thereby " it seems highly unlikely that molecular hybridization of fossil samples fixed on a membrane and probed with fossil extracts could be used as a method to discriminate such related genomes as those of human and chimpanzee, even more to discriminate human from Neanderthal DNAs that are expected to be even closer" Why would anyone conclude this ? Just passing it along.

Admin -- I have received two e-mails from this poster asking that:
As I've said over and over we aren't able to edit the message so why try I'd rather just delete it if it's all the same to you (m=77) As I do not have admin privilages I cannot do this for this post (I can only delete from my posts). If you want I can forward the whole e-mail for verification. Thanks.

That's kind of what I figured. It's not like it bothers anybody being there. Thanks.
