Arciferal Pectoral Girdle of Amphibians — An Instrument for Recognizing Right- and Left-Handedness?

Valentin G. Borkhvardt, E. B. Ivashintsova


There was a high statistically significant difference in the number of top or bottom right and left epicoracoids between common newts in which the right (1) and the left (2) front limbs had been amputated at the larval stage. These data support the idea that contractions of the limb muscles determine the arrangement of the epicoracoids in arciferal girdles.
