Anyone see that show last night on Science Channel?

    There is a new series on Dinosaurs on the science channel: Dinosaur Revolution .
    Last night before the series there was a show on making live dinosaurs, called "Dinosaurs: Return to Life?" Had to think of Aqua Eyes, because they were talking his language. Genome, experimenting with chicken embryos in the egg to make teeth, tails.
    I like my peas the most since they are so beautiful, so I placed this post here, & all our birds are our own little dinos.
    Everyone with birds will want to see that show when it shows again, great science fiction stuff turned reality.

    Quote:The basic idea is that the skeleton of many genes that existed in birds' dinosaur ancestors are still to be found in their genomes. Mutations, other genes, attached proteins, etc. have silenced and/or degraded them, but many are still in there. So while we don't see birds with true teeth anymore (though there are fossils of birds with teeth...the one I always remember is Hesperonis, which looked a lot like a grebe), we don't need to put a "grow teeth" gene in there to get teeth. We can cause teeth to grow by basically "unsilencing" what was silenced.

    The history of our ancestry is written in our DNA. In humans, we find the evidence of a fusion on Chromosome 2, which resulted from two smaller ancestral chromosomes combining to form one larger chromosome. This explains why humans have one pair fewer chromosomes than our closest relatives. There is also a graveyard of ancient infections and plagues, with bits of inserted viral DNA embedded within our own -- non-active, but passed on from generation to generation, like that set of china from Grandma.

    The learning never stops here, does it? [​IMG] I've always enjoyed hearing about this area of science.

    Thanks for your input AquaEyes, I've enjoyed reading your posts since you've joined. [​IMG]

    Thanks,
    Walter

    Quote:And thank you for the compliment.


    If you want to read some first-hand research, check out PubMed and search around for a topic that interests you. I know it says "medical science" but there's a lot on the things you're saying you enjoy.

    Oh, and learning should NEVER stop!

    X 2 -- it's nice to people who don't mind sharing their knowledge.
    Knowledge is Power!
