Three members of a gene family called NOTCH2NL may have been involved in the evolution of humans’ big cortex.

Authors of a new study suggest that 520-million-year-old structures, previously identified as the brains of ancient arthropods, are instead preserved microbial biofilms.

The results of a historical primate behavior analysis suggest that species with fruit-filled diets evolved larger brains.

Humans burn calories faster than any other primate, researchers report.

Exceptional neural fossil preservation helps answer questions about ancient arthropod evolution.

A new study shows that kangaroos are predominantly left-handed.

Researchers map the expression patterns of 1,000 genes in the human brain.

The human brain is an organized, 3D grid composed of elegant, ribbon-like fibers.

Gene expression controlled from afar may have spurred the spurt in brain evolution that led to modern humans.
