Canadian scientists probing a mountaintop in the Northwest Territories have
discovered what they believe to be the oldest evidence of animals on Earth,
The microscopic but distinctively patterned remains —unearthed from a dramatic pinnacle in the Mackenzie Mountains about 800 kilometres northwest of Yellowknife — are interpreted by the research team as rock-encased residues from the decomposed tissues of a primordial sea creature that was the earliest common ancestor of all animals, including humans.
