What We Are Reading Today: ‘The Machines of Evolution and the Scope of Meaning’

Author: Gary Tomlinson

In this groundbreaking book, Gary Tomlinson defines a middle path. Combining emergent thinking about evolution, new research on animal behaviors, and theories of information and signs, he tracks meaning far out into the animal world. At the same time he discerns limits to its scope and identifies innumerable life forms, including many animals and all other organisms, that make no meanings at all.

What We Are Reading Today: ‘Ghost Sharks’

Authors: David A. Ebert, Jenny M. Kemper, Brittany Finucci, Dominique A. Didier, and Marc Dando

Ghost sharks, also known as chimaeras, are cartilaginous fish related to sharks and rays sharing a common ancestor dating back some 400 million years.

These extraordinary fish are found in virtually every ocean on the planet, and while a few inhabit coastal waters, most live at depths that can make them incredibly difficult to study and observe.

This comprehensive reference book covers every known species of chimaera to date.
