I saw that! And it's not the computer ALU either.

Actually, their posts were eerily reminiscent of f.Christian's. No wonder they died out...

Yep! Lousy grammar, but plenty of punctuation!

Humans and chimps share more than 98 percent of their DNA, so a few genes must make a big difference.

Another 1% difference and you are a mouse… From mice to men…
Hmmm?… Humans, chimps, and mice – whom are more closely related?

I couldn't find the figures for man vs. mouse, but rabbits' DNA is 33% different from humans, or 15 times or so more than chimps. IIRC mice are in that ballpark.

Just to tie into the discussion of LINE-1 sequences, the mutation in the enzyme gene under discussion was caused by an Alu sequence, a member of another repetetive DNA (aka junk) family.

Interesting . . . a "loss of function" mutation turned into a "good" mutation - I thought this "never" happened :-) or did I misunderstand?

Correct!

How many other Alu sequence mutations have we noticed that might have contributed to human development?

That's a fine anthology site! A link off of your link leads to the following:

Taxonomy, Transitional Forms, and the Fossil Record.

The Miacids in turn are very similar to the earliest representatives of the Families Canidae (dogs) and Mustelidae (weasels), both of Superfamily Arctoidea, and the Family Viverridae (civets) of the Superfamily Aeluroidea. As Romer (1966) states in Vertebrate Paleontology (p. 232), "Were we living at the beginning of the Oligocene, we should probably consider all these small carnivores as members of a single family." This statement also illustrates the point that the erection of a higher taxon is done in retrospect, after sufficient divergence has occurred to give particular traits significance.

Once again, JennyP is an outstanding source of information.

Way to go girl!

taxonomy and anatomy - two places where the genius types have gone overboard with the latin.

There are about 1x10^5 Alu sequences in the human genome. About 5000 of those are human specific. Most active events are neutral, a few are disease causing and a few have novel effects. Several notable ones have been studied. A few cause alternative splicing of mRNA, causing protein variability. Another has been identified as a transcriptional enhancer.

Those are the recent events. Alu sequences make up 10% of the human genome. What makes us human is a lot of Alu.

Yes but we share just about the exact same genes with the fugu fish:

Over 30,000 Fugu genes have been identified in our analysis. The great majority of human genes have counterparts in Fugu, and vice versa, with notable exceptions including genes of the immune system,
From: Fugu Fish

Who would have thunk we really are closer to fish than to rabbits! Seems evolutionists need to start redrawing them trees!

This reference is billed as "A thorough compilation of mobile elements, which have been functionally significant in the genome."

Britten, R. J. Mobile elements inserted in the distant past have taken on important functions. Gene 205, 177-182 (1997).

I'm sure we have that "rag" ;-) in the library here. If I can find time, I'll take a look at it. Med school is really cutting into my goof-around time.

Nope, apples & oranges almost. Having "counterparts" for most of our genes is hardly the same as most genes being exactly (or almost exactly) alike. It's similar to how most animals have a gene for some variation of cytochrome-c, but the sequences themselves can be way different.

(Satan wins again!!! :-)

Nice comeback, however, not quite correct. The reason we can learn from the fugu fish is that the genes are quite close to those of humans. Very few genes are exactly alike between species. What the fugu shows is that it is not genes that are the source of complexity but the DNA which the evolutionists have incorrectly called junk.

Sure, but it's that inexactness which they measure when determining genetic distance between the species.

That may well be true too, but that is different than saying the fugu is more closely related to Man than is the mouse.

Surprising indeed! But then, maybe not:
