Biological evolution provides a creative fount of complex and subtle adaptations, often surprising the scientists who discover them.

Exploring the coevolution of predator and prey morphology and behavior

no code implementations • 29 Feb 2016 • Randal S. Olson, Arend Hintze, Fred C. Dyer, Jason H. Moore, Christoph Adami

In this model, we observe a coevolutionary cycle between prey swarming behavior and the predator's visual system, where the predator and prey continually adapt their visual system and behavior, respectively, over evolutionary time in reaction to one another due to the well-known "predator confusion effect."

Exploring the evolution of a trade-off between vigilance and foraging in group-living organisms

no code implementations • 8 Aug 2014 • Randal S. Olson, Patrick B. Haley, Fred C. Dyer, Christoph Adami

Despite the fact that grouping behavior has been actively studied for over a century, the relative importance of the numerous proposed fitness benefits of grouping remain unclear.

Predator confusion is sufficient to evolve swarming behavior

1 code implementation • 14 Sep 2012 • Randal S. Olson, Arend Hintze, Fred C. Dyer, David B. Knoester, Christoph Adami

Using an evolutionary model of a predator-prey system, we show that predator confusion provides a sufficient selection pressure to evolve swarming behavior in prey.
