fossilized tree sap that hoards ancient DNA and stops traffic at intersections worldwide

means A hard, translucent yellow-to-orange fossilized tree resin, prized as a gem and sometimes preserving trapped insects — and, by extension, the warning color between green and red on a traffic signal.

from From Old French 'ambre', borrowed from Arabic 'anbar', which originally meant ambergris — the waxy substance from sperm whales. Confusingly, medieval Europeans used the same word for two washed-up sea treasures: the whale stuff and the fossil resin. To tell them apart they spoke of 'yellow amber' for the resin and 'grey amber' (ambergris) for the whale's, and eventually 'amber' on its own settled onto the golden stone we know today.
