PaintedWolf ..I'm glad you acknowledge your deceit in purporting that God made PNA, LNA, GNA but chose to only use RNA & DNA. One really does have to check your remarks for accuracy.
Autodidact is another where one must check every comment for deceiptful information. Ribosomes appear to NOT be all the same as alledged. You are a liar. Indeed humans supposedly evolved from bacteria yet the ribosomes SIGNIFICANTLY differ in the 3 domains of life. Looser!
Wiki: Ribosomes from bacteria, archaea and eukaryotes (the three domains of life on Earth), have significantly different structures and RNA sequences. These differences in structure allow some antibiotics to kill bacteria by inhibiting their ribosomes, while leaving human ribosomes unaffected. The ribosomes in the mitochondria of eukaryotic cells resemble those in bacteria, reflecting the likely evolutionary origin of this organelle.[1] The word ribosome comes from ribonucleic acid and the Greek: soma (meaning body).Archaeal, eubacterial and eukaryotic ribosomes differ in their size, composition and the ratio of protein to RNA. Their active sites are made of RNA, so ribosomes are now classified as "ribozymes".[2].
So creationists look here below. Look at this data about widespread morphologically identical species that have significant genetic differences beween them. Initially different species could not mate..then..oh sorry there are some exceptions and now.... some species are visually identical, can't mate and yet show significant genetic differences. What a mess. Yet the faithful contine to battle on. Your faith in the face of adversity is to be admired.
OMG another load of inconsistency in their term 'species'. Evolutionists can't even define their own terms with any veracity. I do not understand why some of them want to prattle on and show how educated they are in biology, yet they can't even accurately and consistently describe the most basic of their concepts. Loosers!
Species Detectives Track Unseen Evolution
ScienceDaily (July 20, 2007) — New species are evading detection using a foolproof disguise -- their own unchanged appearance. Research published in the journal, BMC Evolutionary Biology, suggests that the phenomenon of different animal species not being visually distinct despite other significant genetic differences is widespread in the animal kingdom.
- DNA profiles and distinct mating groups are the only way to spot an evolutionary splinter group from their look-alike cousins, introducing uncertainty to biodiversity estimates globally.
Markus Pfenninger and Klaus Schwenk searched the Zoological Record database (1978-2006) to pinpoint reports of hidden (cryptic) species both biogeographically and taxonomically, and found 2207 examples. Pfenninger and Schwenk, who are from Germany based at J.W. Goethe-Universität in Frankfurt found evidence for cryptic species evenly spread among all major branches of the animal kingdom. They also found that cryptic species were just as likely to be found in all biogeographical regions.
The findings go against received wisdom that the insect or reptile branches of the animal kingdom are more likely to harbour cryptic species, and that these are more likely to be found in the tropics than in temperate regions. Zoologists should therefore consider factoring in a degree of cryptic diversity as a random error in all biodiversity assessments.
A cryptic species complex is a group of species that is reproductively isolated from each other - but lacking conspicuous differences in outward appearance. Researchers using techniques such as polymerase chain reaction (PCR) and DNA sequencing have increasingly discovered - often unexpectedly - that similar-looking animals within a presumed species are in fact genetically divergent.
As well as highlighting hidden biodiversity among creatures zoologists have already catalogued, the findings have implications for conservation efforts. Another possibility is that pathogens, parasites and invasive species disguised as their relatives may yet remain undetected, representing a potential human health threat.
