In other words, the metabolic path evolved backwards.
In the retrograde model, pathways evolve backwards from a key metabolite [ 2].
The group hoped to capitalize on the differences that emerge as a virus evolves to work backwards to the earliest MERS ancestors.
The role of the head posture that is tilted forwards and backwards evolved as a consequence of the pathological curves of the sagittal plane (kyphosis and lordosis) which were mainly examined within the framework of the study of the development of the sagittal and vertical jaw anomalies [ 5- 10].
We show that on a manifold whose Riemannian metric evolves under backwards Ricci flow two Brownian motions can be coupled in such a way that their normalized L-distance is a supermartingale.
It moves almost as fast as the creature -- which is named Dren (nerd backwards) -- evolves into an adult that looks tantalizingly human (except, of course, for that tail).
Eight rate parameters constitute the dependent model, which assumes that each character evolves (shifts forwards and backwards) at different rates depending on the state of the second character.
While grunge looked inwards, rock looked backwards and mainstream pop remained stuck in neutral, dance music forged forward, evolving and spawning myriad sub-genres – happy house, techno, trance, jungle, drum'n'bass.
If the tests are evolving with the requirements, they serve as a watchdog to make sure we're not rolling backwards.
Gene trees evolve within the species tree, in a backwards process described by the MSC; thus, lineages "coalesce" on the branches of the tree, as they move from the leaves of the species tree towards the root.
