摘要

Worm sperm have staying power. Embedded in a fossilized cocoon, mineralized sperm from what may have been a leechlike worm have stuck around for about 50 million years. The ancient sperm fossils predate the previous record holders - amber-preserved sperm from tiny insects called springtails and petrified sperm from mussel shrimps-by at least 10 million years.
