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:

    I feel the carousel starting slowly
    And going faster and faster: desk, papers, books,
    Photographs of friends, the window and the trees
    Merging in one neutral band that surrounds
    Me on all sides, everywhere I look.
    John Ashbery (b. 1927)

    Although I mean it, and project the meaning
    As hard as I can into its brushed-metal surface,
    It cannot, in this deteriorating climate, pick up
    Where I leave off.
    John Ashbery (b. 1927)
