Horse cloned, so now watch the Gulf Arab money flowing into this promising avenue of research that might lead to more racing champions. Did you know that Secretariat had a heart twice as big as normally found in a thoroughbred? Of course, most of his offspring regressed back toward the mean, but this sort of technology might help us figure out if Secretariat was a genetic or developmental freak (did a certain combination of genes allow him to support a heart so out-sized, or was it something in the environment or placenta?).
