Paleontologies! Perspectives on Morphological Evolution

The fossil record documents over three billion years of evolution. Darwin considered the general succession of morphologies in the fossil record to corroborate the basic idea of evolution by natural selection. However, he also recognized aspects of the fossil record that challenged his ideas. For example, did the sudden appearance of higher taxa reflect a different underlying model of evolution...

Teachers’ Perceptions of and Concerns for the Implementation of the New First Grade English Textbook at Iran’s Public Junior High Schools

Changing the English textbook of the first grade junior high school at Iran’s public schools after 27 years has sparked researchers’ interests in conducting evaluations of the new English textbook to get insights into its strengths and weaknesses. In line with this trend, this study aimed at evaluating the new textbook (Prospect 1) from teachers’ perspectives. To attain this objective, 30 junio...

Ecological Networks: Information Theory Meets Darwin's Entangled Bank

Is it possible to untangle the 'entangled bank'--Darwin's metaphor for the complexity and connectedness of species in the natural world? Studies on webs of species interactions suggest so, but a major question remains unanswered: how specialized are different ecological networks? By considering how strongly species interact with each other, information theory may give the answer.
