A new normal: Study explains universal pattern in fossil record

Instead of the typical bell-shaped curve, the fossil record shows a fat-tailed distribution, with extreme, outlier, events occurring with higher-than-expected probability. Using the same mathematical tools that describe stock market crashes, SFI researchers explain the evolutionary dynamics behind this universal pattern in the fossil record and uncover "a new normal."

Toward a New Understanding of Aging, Adaptation, and the Arrow of Time

While time and age in standard dynamical systems are treated as simple clocks that run at a constant rate, the human experience of age is measured by consequences. In this talk on Tuesday, May 21 at 7:30 p.m., physicist Jean Carlson will illustrate the interplay between biological aging, adaptation, and the arrow of time through examples taken from her research and focus areas of a five-year Santa Fe Institute research theme.
