## Executive Summary
A 550-million-year-old fossil may represent the earliest animal with a head and the first evidence of right-handedness in the animal kingdom.

## Intelligence Brief
Fossils of an ancient sea creature, described by some reports as a worm, may provide the earliest known evidence of handedness. This creature, dating back 550 million years, is identified as the earliest animal to possess a head.


Coverage from CNN, The New York Times, and Popular Science emphasizes that the discovery could reveal the first-ever instance of 'right-handedness.' Other outlets, including KSL News, KCRA, and Sci.News, highlight the fossil's significance as a landmark for both cephalization and lateralization. Future analysis will likely focus on whether these fossils definitively confirm the earliest evidence of handedness in animals.
