Also are you implying that all the genic differences are only incorporated in the human Genome? Remember, we record the evolution by looking at the differences within each species genome, not just one. Chimps continued to evolve also.
There are many complexes of genes and segments that they dont fully understand functions yet. As Svannte Pabo said (hes the one that decoded the human v Neanderthal genome and found it also quite cumulatively variable)
"Im still amazed at how close the genomes are" When you look at the differences in chromosomes we can see that the "fusing" of the chimps no 2 and 3 became our number 2 chromosome and even so, there are many differences in the "bar code" that dont make exact comparisons. We always knew there would be a countable difference but now theyve quantified it.
Remember the differences are only about 0.004% of the entire two genomes . The chimps count is about 3B and humans about 3.5 B, most of this is in the introns , which is where evolution weeds out the junk.
The interesting thing is the overall "bauplan" that is recorded in the genomes of man and chimp. Everything from the Hox to the PIBf genes, show the amazing economy of how evolution works, in that , once a specific "workable" solution is preserved and recorded on the genome, it is passed on as a "stock toolbox answer" for a specific trait. That takes the "Magic" out of the Creationists wishes in that we understand that everything is , even if only slightly, related in the internal blueprints and all we are doing now is counting "backwards" using the living genomes as a starting point. We also have the genome of Mus musculus (house mouse) and can see the growing bauplan for mammalian configuration.
Not any problem at all.
Hi Farmerman,
Yes I know that referring to the differences as a percentage makes it seem very small ( the article referred to the similarities at between 96% - 99%) , however in raw numbers that still leaves the differences at 40,000,000 .
Assuming that half of the changes occurred in the chimps and half in the humans; and that half of the changes were dominant ( and thus passed on to successive generations ) and half were recessive, then you need
200 genetic changes / mutations PER GENERATION to achieve this difference.
It really doesn't matter which gene the differences occur on, they still must occur. And the changes all have to occur within the lineal descendants of the same humans for the mutations to accumulate.
(As an aside:
Even if you accept by leap of faith that this rate of mutation/ genetic change can and did occur, then you must assume the same rate of change could occur in other humans as well and we should see many examples of humans having evolved into or well into the process of evolving into something else due to the enormous genetic differences that are occurring. This we do not see.
The same is true for other species. If evolution can produce this many changes in a rapid fashion there should be a
much larger number of transitional species available to observe , BOTH FOSSILIZED and LIVING EXAMPLES, than we see today. But there is not.
Why isn't this rapid evolution occuring everywhere now?)
The point is that evolutionists cannot account for the sheer numbers of genetic differences between species, but to uphold the Theory they must assert that it happened anyway.
