I thought that the fugu did that, since its genome is only about 10% the size of ours.
Although the Fugu genome contains essentially the same genes and regulatory sequences as the human genome, it carries those genes and regulatory sequences in approximately 365 million bases as compared to the 3 billion bases that make up human DNA. With far less so-called junk DNA to sort through....
Yes, the fugu is another demonsration of the same thing. It also proves that not all fish products are good for you.
