1. Briggs and colleagues discovered fossils of 4cm-long eel-like animals from the Early Carboniferous of Scotland, each of which carried a set of conodont elements at the anterior end.
2. Right posterior premaxillary and anterior maxillary teeth in lateral view.
3. The incisors are lost first, with the break up of the anterior part of the premaxilla, and then the molars are lost as the alveolar border becomes damaged.
4. Anterior expression becomes restricted to r4 and gradually regresses posteriorly along the spinal cord as seen in the lateral views at 8.5 d.p.c.
5. These extra digits do not come from the graft, but from the cells adjacent to it in the anterior part of the bud.
6. A. rooted vole molar showing chipping of edges and pitting and flaking of the enamel surface (25); B. enlargement of same (45); C. tip of lower incisor showing chipping of edges of enamel and pitting and flaking of the enamel surface (20); D. enlargement of same (75); E. shrew mandible showing pitting of bone surface near the alveolar border and flaking of the enamel surface of the teeth (40); F. enlargement of the anterior tooth (165); G. shaft of limb bone showing pitting and flaking of the surface (12); H. enlargement of same (112).
7. If a piece of tissue is taken from the posterior margin of a mouse limb bud and grafted into the anterior region of a chick limb bud, it too can specify additional digits, but the digits are, of course, chick digits.
8. Based on evolutionary considerations, the small anterior digit is designated digit 2, the large central one as digit 3, and the posterior, middle-sized digit, as digit 4.
9. This is thought to reflect our evolutionary history in that as the head became larger, the development of the anterior somites was modified.
10. This is in contrast to previous findings, in which cultures of dissociated anterior mesenchyme were shown to be more responsive to FGF than were cultures of posterior mesenchyme.
11. detail of same (112); J. murid molar from white tailed mongoose assemblage showing cracking but little digestion (8); K. enlargement of same (188); L. shrew anterior teeth from small-spotted genet assemblage (19); M. enlargement of same (140); N. enlargement of molar with enamel nearly all removed by digestion (35).
12. The results were equivocal, but to his surprise he found that when he grafted the tissue to the anterior margin of the limb there was a dramatic change in the development of the limb - a whole new set of digits developed: he had discovered the polarizing region.
13. These muscles are called the deltoids and have 3 "heads"; anterior (front), lateral (side) and posterior (rear).
