New Genetic Study Of Tadpole Shrimps Casts Doubt On The Validity Of The Term 'Living Fossil'
2013-04-02 08:10:15

PeerJ The term 'living fossil' has a controversial history. For decades, scientists have argued about its usefulness as it appears to suggest that some organisms have stopped evolving. New research has now investigated the origin of tadpole shrimps, a group commonly regarded as 'living fossils' which includes the familiar Triops. The research reveals that living species of tadpole shrimp are much younger than the fossils they so much resemble, calling into question the term 'living...

Tadpole shrimp are pests of rice production systems in California and have recently been found impacting Missouri and Arkansas rice fields. The shrimp feed on rice seedlings and uproot them during foraging, and their foraging behavior causes water to become muddy, which reduces light penetration to submerged seedlings and delays the development of the rice plant.
