Hi Phospholipid, this statement is also inaccurate.
quote:The differences in glyosylation which define blood types come from several well defined mutations. mutations Some of these changes in glycosylations, mutations within the glycosylating protein, can confer disease resistence seminar on blood types This is a well understood phenomina. ------------------"Chance favors the prepared mind."

Phospho, you really should not make statements like
quote:when you are unaware of the "facts". Organisms mediate their own mutations, albet unwittingly, all the time. Please look at some of the articels associated with this one here. I have copied one abstract below. quote:It essentially gives an example of organisms which have sequence mediated increases in copy errors, i.e. mutations. Many of the se mutations increase in times of stress to the organism which results in cellular stress and increased mutation. Most of this data is currently applicable to bacteria although there are many applications to multicellular and larger organisms also listed on this and other sites. And you never addressed my post in this thread re: blood type mutations and their beneficial effects, or are you calling a series of well defined mutations part of your variety which came pre-packaged by a diety who put the diseases in for the mutations to be beneficial for ? ------------------"Chance favors the prepared mind."

More than anything else these stats represent to me the failure of the schools to teach biology properly. It also illustrates the pressure brought to bear on both public schools and on companies that make textbooks to delete as much as possible any substantive reference to evolution and the major theories explaining it within the public school system.
Now, creationists will WHINE about their point of view not being allowed in schools (where,in a science classroom, it should not be anyway) while all the while trying to prevent the teaching of science in its proper place. Their mis-statements concerning evolution require an audience ignorant of the real theories surrounding evolution if they are not to be challenged.

Hi Mammuthus, Hi PPL. FYI PPL is a very old organic/physical biochem shorthand for PhosPhoLipid, hope that you do not mid if I use that for brevity.
PPL, with respect to definitions of science I would like to refer you to Kitcher, the author who you mistakenly claimed did not support evolution as a valid scientific theory as well as books by others, here are a few into books on the philosophy of science and what constitutes science inthe authors view:one, two, and in a slightly upfdated form three. I am of the opinion that all students entering the sciences would benefit from taking at least one philosophy of science course to give them a better all-around understanding of what it is that they plan to do. Another short comment, after reviewing your comments re: mutations and the "control" of these mutations by the organism I have come to the conclusion that you are operating under a few misconceptions. Mutations occur with varying probabilities over both space (the location within the genome depending on the sequence) and time (ie, when the mutation occurs). Neither one of these probabilities appears to be fixed with changes based on responses to environmental stress. That is where some of the "non-randomness" statements of peopel such as Lee Spentner (sp?) come from. They are viewing all random events as equiprobable, this is not the case. When you view things as altered probabilities a pattern starts to emerge which has just started to be defined over the last 10 years or so. I would suggest Darwininteh Genome for an excellant overview, even if one does not totally agree with some of the authors conclusions. ------------------"Chance favors the prepared mind." L.

Like mostother people in the field he has some very valid point but takes his arguements a bit too far, kind of like Popper. IMO, to use an analogy, the ground must in some way be fertile for an idea to take root. Where I think that Kuhn goes to far in that he seems to veer to the position that the different groups on either side of a revolution can not even undertand the other. If that were the case all revolutions would start from scientific ground zero, we would constantly be reinventing fire and the wheel.
Oh, and in case certian pseudo-scientific "great men" or self annointed dieties try to use this, it does not mean that you can use this as an excuse for the non-acceptance of "scientific ideas" sans merrit. ------------------"Chance favors the prepared mind." L. Pasteur Taz Sorry for the typos. I have to do a snap presentation in an hour or so and am a little swamped. [This message has been edited by Dr_Tazimus_maximus, 05-21-2003]
