The curator of our university Entomology museum, John Marris, excitedly popped into my office earlier today to share this neat new study on ant-associated beetles, by
Yu-Cheng Feng and colleagues.

These small beetles live inside ant nests. Not only have they evolved cunning ways to co-exist with the ants, but they have also evolved *handles* to help the ants carry them about. The phyologeny of the subfamily Chlamydopsinae suggests that these beetles have independently evolved ant handles several times.

"Our findings provide direct evidence that the characteristic surface relief of chlamydopsines, at least partly or in some cases, serves as a mechanical adaptation for ant‑mediated transport"

TITLE: Scientists challenge a 70-year-old “lizard brain” myth

A long-standing picture of brain evolution as newer, rational layers stacked on top of an ancient “lizard brain” may be deeply misleading. Researchers found that evolution instead appears to balance two competing styles of brain wiring, expanding one while shrinking the other depending on what an animal needs to survive.

When an animal moves, its visual system adjusts its neuronal activity to process the changing environmental input, but this adjustment operates on the same mathematical evolutionary principles across both mice and primates despite differing sensory outputs.

Interspecies cooperation is a behavioral phenomenon where animals from different species work together for mutual benefit by exchanging information. This teamwork relies heavily on communication through specific cues and signals to coordinate complementary actions and achieve shared goals.

Behavioral ecology is the study of the evolutionary basis for animal behavior due to ecological pressures. It examines how behavior evolves, functions, and adapts in response to an organism's environment.
