Can Selection Cause Genetic Change?

Selection and Genetic Change

Can increasing carbon dioxide cause climate change?

The realistic physical functioning of the greenhouse effect is reviewed, and the role of dynamic transport and water vapor is identified. Model errors and uncertainties are quantitatively compared with the forcing due to doubling CO2, and they are shown to be too large for reliable model evaluations of climate sensitivities. The possibility of directly measuring climate sensitivity is reviewed....

Complete genetic linkage can subvert natural selection.

The intricate adjustment of organisms to their environment demonstrates the effectiveness of natural selection. But Darwin himself recognized that certain biological features could limit this effectiveness, features that generally reduce the efficiency of natural selection or yield suboptimal adaptation. Genetic linkage is known to be one such feature, and here we show theoretically that it can...

How Globalization Can Cause Fundamental Curriculum Change: an American Perspective

Globalization, unlike 20th century social and economic developments, will cause fundamental rather than merely incremental educational change. ‘Globalization’ refers to a complex of technological and economic factors including the global spread of communication technology networks, and the global integration of product and labor

Climate change can cause spatial mismatch of trophically interacting species.

Climate change is one of the most influential drivers of biodiversity. Species-specific differences in the reaction to climate change can become particularly important when interacting species are considered. Current studies have evidenced temporal mismatching of interacting species at single points in space, and recently two investigations showed that species interactions are relevant for thei...
