It's been a while since I've seen a thread dedicated to fossils and genomics, thought it would be a nice change. We are continuously being inundated with fossils that are supposed to confirm that Chimpanzees and Humans have common ancestry. The strange thing is that with five million years having gone by since the split not one Chimpanzee skull has been unearthed. Were the Chimpanzees not alive today there would be no fossil evidence that they ever existed. The human skull is usually just over 1300cc while a Chimpanzee skull is just over 400cc, which is a pretty big difference. Over the years I have researched the various papers on comparisons between human and chimpanzee genomes and the molecular basis for such a dramatic expansion of the human brain from that of apes is completely unknown.
As a matter of fact, changes in brain related genes result in disease and disorder. So where do we get this myth of the Stone Age tool making ape man? Check this guy out:
Be of good cheer my Creationist brethren, there are ways of answering all of this and the answers are staggering in their audacity, motives and scope. So I ask you to bear with me patiently. Let's just get this in focus, just under 2 million years ago a distinctly humanoid looking skull marks a major transition to the modern human brain.
Like I say, this kind of fossil evidence had me reeling and rethinking my theology, I was almost a theistic evolutionist at this point. Then I discovered comparative genomics, a profoundly important category of comparisons of the genomes of humans and chimpanzees. From the time of the publication of the findings of the Human Genome project till the publication of the Initial Sequence of the Chimpanzee Genome I was searching out everything I could find on the subject. After learning as much as I could on the subject matter I came to realize this apparent transition was a myth.
This was the key finding that sent me back to a young biological earth natural history. I am now convinced that the profound differences between Chimpanzee DNA and Human DNA, particularly with regards to human brain evolution makes the Darwinian philosophy of common ancestry simply untenable:
That's some pretty broad subject matter I would think irresistible to theistic evolutionists interested in the science behind modern natural history. Feel free to respond as you see fit and hopefully we can talk a little about fossils and comparative genomics.

Louis also wrote "Finding the World's Earliest Man" for the September 1960 issue of National Geographic, estimating the fossil's age to be 600,000 years old. University of California, Berkeley, geochemists Garniss Curtis and Jack Evernden used potassium-argon dating to re-assess the site, finding that Olduvai's Bed I was actually about 1.75 million years old. Such an application of geochronology was unprecedented; OH 5 became the first hominin to be dated by that method. The same process was used for OH 7, the holotype of Homo habilis (handy man). (OH 5 'Olduvai Hominid number 5')
This fossil nearly did it for me, notice the crest down the middle, very much like a gorilla. Yet it has many of the features of a gracial skull, not unlike Chimpanzee and Human skulls. Unmistakably, this thing is a transitional. Louis and Mary Leakey would become the celebrated Paleontologists who came up with treasure troves of Hominid fossils and another very interesting assortment of what they claimed to be tools. The theory goes, this was the beginning of a species of Stone Age ape to man transitionals culminating in the emergence of modern humans a couple a hundred thousand years ago.

Only two bases (out of 118) are changed between chimpanzee and chicken, indicating that the region was present and functional in our ancestor at least 310 million years (Myr) ago. No orthologue of HAR1 was detected in the frog (Xenopus tropicalis), any of the available fish genomes (zebrafish, Takifugu and Tetraodon), or in any invertebrate lineage, indicating that it originated no more than about 400Myr ago (Pollard et al. Nature Magazine 14 September 2006)
So from a time close to the Cambrian explosion, until just under 2 million years ago, this gene only allowed 2 substitutions. Then suddenly is allows 18. I cannot and will not accept such an impossible giant leap based on the naturalistic assumptions of Darwinians. Over time, I spent more time on here discussing theology and Biblical expositions, and far less time debating the more atheistic bent of the common discussion boards.
