Male battles split species apart

This post is by MSU postdoc Jason Keagy How do species form? Stated more precisely, how does one species become two? This turns out to be an immensely difficult question to answer, because 1) species are not always distinct entities (species … Continue reading

Tortoises, hares, and topography: how fitness landscape structure affects the speed of adaptation

Hello fellow BEACONites and interested members of the public, I’m Josh Nahum, a postdoctoral fellow, who was at the University of Washington during the early years of the Beacon Center, but now I’m doing research at Michigan State University (more … Continue reading

Visualizing coevolution in dynamic fitness landscapes

This post and video is by postdoc Bjørn Østman and graduate student Randy Olson, both at Michigan State University. The fitness landscape is the framework for thinking about evolutionary processes the same way the phylogenetic tree is how we think about … Continue reading

Using fitness landscapes to visualize evolution in action

BEACONites Bjørn Østman and Randy Olson created a video to visualize evolution in action using fitness landscapes. Read about it below! Fitness landscapes were invented by Sewall Wright in 1932. They map fitness, or reproductive success, of individual organisms as a function … Continue reading

BEACON Researchers at Work: Holey Fitness Landscapes

This week’s BEACON Researchers at Work post is by MSU postdoc Bjørn Østman, and is also posted on his research website. What do real fitness landscapes look like? Do they look more like the image on the left, a nearly-neutral holey … Continue reading
