The Origin of Flowers: Tree Experts Help Unravel Evolutionary Mystery

Thursday, December 19th, 2013 | Tags: , ,

NC State scientists had a hand in a massive research project highlighted in Science that sheds light on how flowering plants suddenly came into prominence more than 200 million years ago – what Charles Darwin referred to as an “abominable mystery” of evolution. A team of scientists sequenced the genome of Amborella trichopoda, a rare

“Blend in” appears to be the mantra for male Bahamas mosquitofish that live near predators. After all, fish with brighter, more colorful fins or patches are more conspicuous – and standing out with predators around could be a death sentence. So these fish evolve duller colors under the threat of predation, to try and hide

Evolutionary biologists have long suspected that intense competition for mates may speed up the formation of new species, but it has been difficult to find evidence of this effect. In a new paper, NC State biologist Carlos Botero, co-author Nathalie Seddon and colleagues report that bird populations accumulate differences in their physical appearance more quickly

Geological Changes Spurred Dino Diversity

Friday, August 3rd, 2012 | Tags: , ,

New duck-billed and horned dinosaur species in western North America evolved at a blistering pace between 70 and 80 million years ago – blistering by evolutionary standards, of course, which means that new species appeared over spans of hundreds of thousands of years rather than millions of years. Later this species growth appears to weaken,
