Starting The Chimpanzee Genome Project
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. There are nine other major chromosomal differences between chimpanzees and humans: chromosome segment inversions on human chromosomes 1, 4, 5, 9, 12, 15, 16, 17, and 18. After the completion of the Human genome project, a Common Chimpanzee genome project was initiated. 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. Differences between individual humans and Common Chimpanzees are estimated to be about 10 times the typical difference between pairs of humans.

Famous quotes containing the words starting and/or project:
“The toughest thing about success is that youve got to keep on being a success. Talent is only a starting point in this business. Youve got to keep on working that talent. Someday Ill reach for it and it wont be there.”
—Irving Berlin (18881989)
“If we should swap a good library for a second-rate stump speech and not ask for boot, it would be thoroughly in tune with our hearts. For deep within each of us lies politics. It is our football, baseball, and tennis rolled into one. We enjoy it; we will hitch up and drive for miles in order to hear and applaud the vitriolic phrases of a candidate we have already reckoned well vote against.”
—Federal Writers Project Of The Wor, U.S. public relief program (1935-1943)
