A single-gene mutation in common aquarium fish produced a surprising lookalike of ancient species extinct for 400 million years.
Feb 24, 2021 · And now, millions of years later, scientists from Harvard have helped some fish repeat the process - by finding a mutation that makes their fins seemingly start to transition into arms. Does something smell fishy?
Aug 6, 2020 · A research team studying jaw evolution in the earliest known vertebrates—fishes from around 400 million years ago—have found that a single-gene mutation in the toe-sized zebrafish produced a...

Feb 5, 2021 · In a study published today in Cell, researchers identify a gain-of-function mutant in the zebrafish (Danio rerio) that grows an extra set of bones at the ends of two long bones in the fin. The genetic program that makes the extra bones is similar to the instructions for forearm bones in tetrapods.
Dec 6, 1996 · Researchers this month are announcing the first major findings from an international project to generate thousands of mutant zebrafish with telltale embryonic defects. The faulty fish are expected to yield fundamental insights into embryogenesis, the process by which an organism's genetic blueprint unfolds into a body that can slither, swim, or ...
Jul 28, 2020 · Our new research used mathematical modelling – and detailed observations of mutant zebrafish patterns – to get to the bottom of one of nature’s oldest secrets.

Dec 10, 2016 · The small striped 'mud minnow', or killifish, is known for living in heavily polluted estuaries such as New Jersey's Newark Bay and Virginia's Elizabeth River. And scientists have now shown that it survives thanks to an extreme mutation that lets them endure toxic waste.
