The correct Genome numbers for Dna similarity between chimps and humans has been adjusted to 4% this comes from the Genome project. That does not sound like much but if you consider 3 billion base pairs of Dna that is a huge difference.
Human and chimpanzee chromosomes are very similar. The primary difference is that humans have one fewer pair of chromosomes than do other great apes. Humans have 23 pairs of chromosomes and other great apes have 24 pairs of chromosomes. In the human evolutionary lineage, two ancestral ape chromosomes fused at their telomeres producing human chromosome 2
De Grouchy J (August 1987). "Chromosome phylogenies of man, great apes, and Old World monkeys". Genetica 73 (1–2): 37–52. PMID 3333352.
In December 2003, a preliminary analysis of 7600 genes shared between the two genomes confirmed that certain genes such as the forkhead-box P2 transcription factor, which is involved in speech development, are different in the human lineage. Several genes involved in hearing were also found to have changed during human evolution, suggesting selection involving human language-related behavior
By comparing human and chimp genes to the genes of other mammals, it has been found that genes coding for transcription factors, such as forkhead-box P2 (FOXP2), have often evolved faster in the human relative to chimp; relatively small changes in these genes may account for the morphological differences between humans and chimps. A set of 348 transcription factor genes code for proteins with an average of about 50 percent more amino acid changes in the human lineage than in the chimp lineage.
The results of the chimpanzee genome project suggest that when ancestral chromosomes 2A and 2B fused to produce human chromosome 2, no genes were lost from the fused ends of 2A and 2B.
From now on ,please provide your source.
I am not talking about the supposed chromosome fusing from ape to human. I am talking about the Genome being mapped. They use to claim 1% to 2% genetic difference and it is now at a 4% difference. It could go higher because they also found that Junk Dna is no longer considered junk Dna, it has a function.
There ya go princess...
Chimp Genome Assembled; Draft Sequence Aligned With Human Genome -- ScienceDaily
Chimpanzees are the most closely related species to humans. Consequently, comparative analysis of the human and chimp genomes can reveal unique types of information impossible to obtain from comparing the human genome with the genomes of other animals. For more on the scientific rationale for sequencing the chimp genome, go to: http://www.genome.gov/Pages/Research/Sequencing/SeqProposals/ChimpGenome2.pdf.
