Ancient genetic program employed in more than just fins and limbs
Hox genes are master body-building genes that specify where an animal's head, tail and everything in between should go. There's even a special Hox gene program that directs the development of limbs and fins, ...
Tags on fish may act as 'dinner bell' for seals
Sound-emitting tags fitted to fish to track their survival may, paradoxically, be alerting predator seals to their whereabouts, said scientists Wednesday who warned of a "dinner bell" effect.
