Artistic reconstruction of Callichimaera perplexa by Masato Hattori

The ‘Platypus’ of the crab world was an active predator that lurked the Cretaceous seas

January 12, 2022

Eyes are crucial players in the evolution of organisms. They allow an animal to find food, a mate, potential prey, to avoid predators and aid in regulating the internal clock by differentiating day from night. Eyes are also delicate features that tend to be not well preserved in fossil crustaceans.

One such rare finding is Callichimaera perplexa, a 95-million-year-old crab fossil  discovered by senior author Javier Luque, postdoctoral fellow in the Department of Organismic and Evolutionary Biology at Harvard, and fully...

In Memoriam: Edward O. Wilson 1929 - 2021

December 27, 2021

It is with great sadness that we announce the passing of Edward O. Wilson on December 26th. He was 92. Professor Wilson was called "Darwin's natural heir," and was known as "the ant man" for his pioneering work in entomology. He authored over 30 books, twice receiving a Pulitzer Prize along with many other distinguished awards during his six decades at Harvard. He was a pillar of our community and an inspiration to many. He will be greatly missed.

Convergence of undulatory swimming movement across a diversity of fishes

December 7, 2021

Fish move not just by swimming but also by jumping, burrowing, walking, and flying. Many species though move by undulating their body and caudal fin (the tail fin that is used for propulsion). These body-caudal-fin (BCF) swimmers, as they are called, exert force against the surrounding water to support and move their body in an undulating motion. Traditionally, these fishes were classified based on key morphological traits and then grouped into four expected swimming modes based on four model species: eel, trout, mackerel, and tuna. But do all fish swim in certain ways based on this...
