Groundbreaking work out of Penn State demonstrates cows are multi-Y chromosome-carrying PRIMATES!

ImageBoy, do I ever wish I could read the rest of this article. It sounds fascinating. Look out McGraw-Hill, those General Bio textbooks are in for a re-write.

Sorry Malcolm. It couldn’t be missed.

    Hilarious! Would love to see the whole thing, indeed.

      I found the original (in PNAS) and see how this guy got tripped up (well, sorta). Apparently a lot is known about primate Y chromosomes. Humans, Chimps, macaques, etc. have been sequenced, but non-primates have not been as extensively examined. This group found that the cattle Y chromosome had “1,274 genes in the male specific region of the bovine Y chromosome, compared to the 31 to 78 genes associated in the Y chromosomes of various primates.”

      But for the record, this review of the article called cattle primates twice.

    Sadly, Malcolm Flanagan’s article looks like standard journalism to me.
    Slightly misleading headline? Check!
    Confusion between chromosomes and genes? Check!
    No idea about taxonomy/cladistics? Check!
    Nice picture of udders for a review of a paper about the genetic basis of the development of testicles? Check!

    It seems timely, as I woke up this morning to an article about how 41% of Australians didn’t know how long it took the Earth to go around the Sun. And that 30% didn’t know if Humans coexisted with dinosaurs.

    On the other hand, the article I’d really like to be able to read in its entirety is Ti-Cheng Chang et al. in PNAS. I’m wondering if the bovine Y chromosome will turn out to be more typical of mammalian Y chromosomes once we have a representative sample sequenced, and maybe primates are just a little bit odd?

      I really liked all the female cows in the picture too.
      And I was willing to overlooks the genes / chromosomes misunderstanding. Even though it’s essential,there was such a surfeit of problems that I let it slide.

      Glad you enjoyed it.
