The asteroid impact that many researchers claim was the cause of the dinosaur die-off was bad news for marine life at the time as well. But new research funded by NASA shows that microalgae – one of the primary producers in the ocean – bounced back from the global extinction in about 100 years or less.Source: [astrobio.net]

Echoes of Extinction
The mass extinction of the dinosaurs and many other organisms 65 million-years-ago has left lasting effects on the evolution of life on Earth. A team of NASA-funded researchers has performed a global study on marine bivalves, and the results indicate that these organisms began originating new species faster than ever following the end of the Cretaceous period.
