The Humans and Chimpanzees PP article.

    The "Humans and Chimpanzees" PP article.

    I just now noticed that there's no "Physicspost.com Articles" Forum here anymore, so I don't know if there's been any discussion on this article, but I've got a couple of questions:

    1) How different is the DNA of a chimp, when compared to another ape - like a gorilla?

    2) If we are only 95% identical (genetically) to chimps, does that raise any dispute on whether there was a common ancestor, or on how long ago the divergance from that common ancestor occured?

    Any response is appreciated. :smile:

    BTW, this was a very good article, and I highly recommend it.

    A quick remark (I can comment more later) researchers at Wayne State University School of Medicine did genomic analysis of genes and came to the conclusion that chimps belong to the genus Homo.

    http://news.nationalgeographic.com/news/2003/05/0520_030520_chimpanzees.html

    Current naming:
    Chimp - Pan troglodytes
    Human - Homo sapiens

    Suggested change:
    Chimp - Homo troglodytes

    That was about 6 months ago when the article got published in PNAS, I am not sure how the scientific community has digested the news though..

    Here's the archived topic about it...

    I'm still wondering whether "Australopithecus troglodytes" is more appropriate.

    Re: The "Humans and Chimpanzees" PP article.

    I am actually not sure..

    Why would that cause a dispute whether there was a common ancestor?? The 95% identity, is probably based on the entire genomic sequences. In the recent article, researchers looked at genes and found that our identity is much higher: the functional important genes show 99.4% identity, while the not so important ones show 98.4% identity.

    Here is the abstract of the article:

    Where might one find such information?

    Well, at least on how far back in the lineage the common ancestor was...since the divergance would be greater.

    Wow!

    Why's that? Did we also descend from australopithecus (this subject's obviously not my forte )?

    Well, go to PubMed, that is where all biotech related articles get indexed into a searchable database:

    http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=PubMed

    NCBI is the National Center for Biotechnology Information
    NLM is the National Library of Medicine

    I don't think the gorilla genome has been sequences, do you'd have to rely on different genomic techniques to compare the identity between the chimp and the gorilla..
