Biologists trace plants' steady mitochondrial genomes to a gene found in viruses, bacteria
Thu, 09 Jul 2020 15:01:18 EDT
Biologists have traced the stability of plant mitochondrial genomes to a particular gene - MSH1 - that plants have but animals don't. Their experiments could lend insight into why animal mitochondrial genomes tend to mutate.
15-foot-long skeleton of extinct dolphin suggests parallel evolution among whales
Thu, 09 Jul 2020 11:35:18 EDT
A report offers a detailed description of the first nearly complete skeleton of an extinct large dolphin, discovered in what is now South Carolina. The 15-foot-long dolphin (Ankylorhiza tiedemani comb. n.) lived during the Oligocene -- about 25 million years ago -- and was previously known only from a partial rostrum (snout) fossil.
Evolution makes the world less ragged
Thu, 09 Jul 2020 10:52:32 EDT
How does evolution impact ecological patterns? It helps smooth out the rough edges, say researchers. A new review of the history of ecological and evolutionary research establishes a framework to better understand evolution's impact on ecosystem patterns.
Supergenes play a larger role in evolution than previously thought
Wed, 08 Jul 2020 12:53:57 EDT
Large blocks of 'plug and play' genes play a super-sized role in adaption-and may help fill lingering gaps in Darwin's theories.
Tackling coral reefs' thorny problem: Crown-of-thorns starfish
Wed, 08 Jul 2020 10:59:12 EDT
Researchers have revealed the evolutionary history of the crown-of-thorns starfish -- a predator of coral that can devastate coral reefs. Their findings shed light on how the populations of these starfish have changed over time and could potentially help reduce their ecological destruction.
