Bihung Narzary,Soumen Maji,Medalson Ronghangother make contact, either directly or with the aid of ions and metabolites, across the relatively narrow fluid-filled extracellular spaces. Interdependent cells in large animals may, however, be separated by distances of several metres, so that if appropriate coordination is to take place, special

The Determinants of Development Costs,ta (egg-laying mammals), ninety to the order Marsupialia (typically undeveloped young kept in pouches), and the remainder are placentals.

Both for these reasons, and the relatively free liaison between physiologists and amphibians, the group has received considerable scientific attention.

Elevate Design-to-Cost Innovation Using TRIZhat predates the origin of tetrapods by some 200 million years. It is uncertain whether the transformation from an invertebrate ancester took place in fresh water or in the sea (see Page 35), but subsequently fish have adopted both of these environments, as well as inland lakes and springs where the
