Author | Topic: Are we really related to all living things?(Discluding Plants) | |||||||||||||||||||||||

I recently watched a show on Evolution, and I heard something that rather shocked me. They said that we have the same DNA patterns as all living things.

Can you be more specific about what you mean by "DNA patterns"?

We have the same as plants, too.

The TalkingPrimate, all living organisms (with the exceptions of viruses) are DNA based. Creationists use this as an inference for a Common Creator and evolutionists infer common descent.

So, John Paul, if God likes DNA more than RNA, why did He endow some nice little virii (like HIV) with RNA?
Possible evolutionist answers: (1) RNA and DNA work equally well for a virus (2) Virii are polyphyletic.

Firstly, I believe the proper form of saying something is 'not within the limits' is by the word "excluding"; Ex is Latin, meaning 'without'.
Secondly, We share DNA patters with plants as well. Not as high of a percent, but the relationship is still there. According to the single cell theory: A single self-replicating strand of RNA was the basis of life. Everything came from that one strand of RNA, as the replication allowed copies to be made, a more complex cell developed, which in turn clustered together and eventually formed specialized tasks. That, in turn, lead to complex organisms being formed, some groups of cells which photosynthesized food instead of actively gathering it, became the first "green" (or plantlike, photosynthesizing) bacteria, which in turn lead to plants of all sorts. This first cell could have come around by abiogenesis. When the earth cooled after being a spinning, spiraling ball of molten rock and free-floating chemicals, and when the water in the oceans was still in it's young age, some acids were still being mixed up at the bottom of the ocean near the heat vents. Those heat vents could have produced the heat to mix the acids (amino) that would have been required to form RNA strands that were self-replicating. Albeit, the chances were pretty high, (3.044x10^40, according to "Common misconceptions about Abiogenesis, and I think a similar article can be found at talkorigins) one must remember that there are literally millions of vents in the ocean floor. With that in mind, it seems very likely self-replicating RNA strands actually formed on their own, without the help of a creator. (minimum length needed to form self-replicating strands is 28 letters) I hope this has helped. -Kv [Edited to include abiogenisis] [This message has been edited by keenanvin, 01-14-2002]

Well, Gene, now your getting into a more religous conversation. I say this because, many people do not believe there is a God. ( I being one of them ). But also it seems that yes, if he exists he did endow a few little problems in the RNA, but it is still a more religous subject.

I also think what you might be asking about conserved DNA patterns is the fact that the triplet code of DNA and RNA is conserved acrossed most living things. For example, the basepair sequence CTT in DNA is going to code for the amino acid glutamic acid in most living things on Earth, including people.

Well, I merely needed someone to shed some light on the subject, I don't know an awful lot about the DNA sequences. But I thank everyone for shedding some light.

Hello all,
My frist post here. You all did such a really good job of outlining the basic connections of all living things that I'll just also suggest the library has many good popular science books for the layman.

"Possible evolutionist answers: (1) RNA and DNA work equally well for a virus (2) Virii are polyphyletic. "
--Possible answer (3) God Created viruses so they would work like they are suppost to, to regulate and control his creation and give it that 'circle of life' per se. Diseases have a good cause or no unwanted effects where it is suppost to be, untill some really sick people started playing with those green monkeys... --------------

--Problems? What kind of problems does RNA have, it does what its supposed to do. ------------- [This message has been edited by TrueCreation, 01-19-2002]

What's RNA??? Someone can 'shed some light' on this too, right?

quote: RNA stands for Ribosenucleic acic (or I've seen it as Ribonucleic acid). Its very similar stuff to DNA, it uses four bases, like DNAs A,T,C,G (Adenine, Thymine, Cytosine, & Guamine). In RNA, the thymine is replaced with uracil. Its used in ALL cells with DNA, short strands of RNA form alongside the "unzipped" DNA. These matched strands then move out into the cytoplasm where they are used to make proteins. It's a bit more complex than this, but you get the idea. Every protein in your body was manufactured in this way, with RNA acting as messenger between DNA & the cell. The interesting thing about RNA, is its a self replicating molecule in its own right, & is thought to have been a prehistoric precursor of DNA. For DNA to replicate itself, a battery of enzymes is required. But RNA can catalyse reactions to itself. This discovery won the researchers, Cech & Altman the 1989 nobel prize in chemistry. That's not to say RNA was the original self replicating molecule, just a potential "prototype". I know, clear as muck! Mark ------------------Occam's razor is not for shaving with.
