Fins made for walking
Article Abstract:
Scientists Jennifer A. Clack and Michael I. Coates have concluded that the fins of fish adapted into limbs in the water rather than on land. Their work supports research performed by scientist A.S. Romer in the 1950s. Evolutionary evidence featuring organisms such as the fish Acanthostega and the tetrapod Tulerpeton is described. The Acanthostega has physiological similarities to tetrapods.

The dynamics of chromosome evolution in birds and mammals
Article Abstract:
Comparative maps of chicken with human and mouse were constructed to study the dynamics of chromosome rearrangement during vertebrate evolution. It is concluded that the organization of the human genome is nearer to that of the chicken that the mouse, and three possible phases of chromosome evolution are determined.
