MASTEROMETRY AND EVOLUTION, AGAIN

The evolution of photosynthesis...again?

'Replaying the tape' is an intriguing 'would it happen again?' exercise. With respect to broad evolutionary innovations, such as photosynthesis, the answers are central to our search for life elsewhere. Photosynthesis permits a large planetary biomass on Earth. Specifically, oxygenic photosynthesis has allowed an oxygenated atmosphere and the evolution of large metabolically demanding creatures...

Revolution to Evolution and Back Again.

Evolution: Have Wings Come, Gone and Come Again?

Can complex traits be re-evolved by lineages that have lost them? Phylogenetic study now suggests that wings may indeed have reappeared several times within the ancestrally wingless stick insects.

Calcium signalling: IP3 rises again… and again

Recent results indicate that 'regulators of G-protein signalling' may contribute to the generation of receptor-specific patterns of cytosolic Ca2+ oscillations by associating with specific receptors, accelerating G-protein inactivation and responding to changes in cytosolic Ca2+.

Endosymbiotic Evolution: The Totalitarian Nucleus Is Foiled Again

DNA transfer between host cells and their endosymbionts has had a profound effect on the evolution of eukaryotic cells. A new sequencing study suggests that other forces may be equally important.
