Billion-year-old fossils set back evolution of earliest fungi

from Nature

Minute fossils pulled from remote Arctic Canada could push back the first known appearance of fungi to about one billion years ago — more than 500 million years earlier than scientists had expected. These ur-fungi, described on recently in Nature, are microscopic and surprisingly intricate, with filament-like structures. Chemical analyses suggest that the fossils contain chitin, a compound found in fungal cell walls. more
