Yet with a dearth of useful information regarding successful, feasible, and affordable strategies to teach the next generation of physicians, educators must contribute to the national and international discussion. ...

Why are there so many explanations for primate brain evolution?

The question as to why primates have evolved unusually large brains has received much attention, with many alternative proposals all supported by evidence. We review the main hypotheses, the assumptions they make and the evidence for and against them. Taking as our starting point the fact that every hypothesis has sound empirical evidence to support it, we argue that the hypotheses are best int...

Why are there so many species in the tropics?

Known for centuries, the geographical pattern of increasing biodiversity from the poles to the equator is one of the most pervasive features of life on Earth. A longstanding goal of biogeographers has been to understand the primary factors that generate and maintain high diversity in the tropics. Many 'historical' and 'ecological' hypotheses have been proposed and debated, but there is still li...

Why Are There So Many N = 4 Superstrings ?

We demonstrate the existence of three off-shell distinct N = 4 super-strings at the level of manifest locally supersymmetric Lagrangian field theories on the world sheet.
