By Wood, Aaron R Zelditch, Miriam L; Rountrey, Adam N; Eiting, Thomas P; Et al  Abstract.- Evolutionary stasis has often been explained by stabilizing selection, intrinsic constraints, or, more recently, by spatially patterned population dynamics.

By Barwood, Henry  Paleozoic plant fossils with structurally preserved tissues are rare in Alabama. Stems and cones of Mississippian age have been recovered from the Erin Shale in Clay County (Adams et al. 1926; Gastaldo 1995; Gastaldo, Guthrie, and Steltonpohl 1993).

A new study of the skeleton of a one-meter-high race of âhobbitsâ that lived 12,000 years ago in Indonesia shows that they were a species of humanâand that the evolutionary path to Homo sapiens has been torturous indeed.

Parents have been doting over their offspring for a very, very long time, it seems. A South African fossil suggests pelycosaurs -- intermediates between reptiles and mammals that lived in the Permian Period before the rise of dinosaurs -- may have been caring parents 260 million years ago, scientists said on Wednesday.

By Novack-Gottshall, Philip M  Abstract.- The process of evolution hinders our ability to make large-scale ecological comparisons-such as those encompassing marine biotas spanning the Phanerozoic-because the compared entities are taxonomically and morphologically dissimilar.
