Evolutionary leap from fins to legs was surprisingly simple

2016-03-08 13:00:00| LifeSciencesWorld

[NEWS] New research reveals that the limbs of the earliest four-legged vertebrates, dating back more than 360 million years ago, were no more structurally diverse than the fins of their aquatic ancestors. The new finding overturns long-held views that the origin of vertebrates with legs (known as tetrapods) triggered an increase in the anatomical diversity of their skeletons. The research was carried out by Dr Marcello Ruta from the School of Life Sciences at the University o…

Scientists prove key aspect of evolutionary theory

2016-01-26 13:00:00| LifeSciencesWorld

[NEWS] Evolutionary theory predicts that pairs of chromosomes within asexual organisms will evolve independently of each other and become increasingly different over time in a phenomenon called the 'Meselson effect'. While this event was first predicted almost twenty years ago, evidence for it has proved elusive. Now, researchers from the University of Glasgow have demonstrated the Meselson effect for the first time in any organism at a genome-wide level, studying a…

Species' evolutionary choice: Disperse or adapt?

2015-05-01 12:00:00| LifeSciencesWorld

[NEWS] Dispersal and adaptation are two fundamental evolutionary strategies available to species given an environment. Generalists, like dandelions, send their offspring far and wide. Specialists, like alpine flowers, adapt to the conditions of a particular place. Ecologists have typically modeled these two strategies, and the selective pressures that trigger them, by holding one strategy fixed and watching how the other evolves. New research published in the journal Evolution</e…
