Although histones have been classically considered as archetypal examples of slow-evolving proteins, some histone variants do evolve very quickly, particularly those specifically associated with the germinal lineage (that is, H2A.Bbd, sub-acrosomal H2Bs, and so on).
Moreover, paleontologists know that rodents evolve very rapidly.
Deception may, in fact, evolve very easily among fireflies.
A quality rating system, he argues, would be "more flexible because extreme sports evolve very rapidly".
Those mutations allow the virus to evolve very rapidly, approximately one million times faster than the human genome evolves.
It appears that the flu proteins that infected cells select to put on display evolve very little.
Because stars evolve very slowly by human standards, a given star will fall in a specific position on the diagram, and how its position might change over the eons has been a matter of considerable speculation and controversy.
Some proteins evolve very fast; the fibrinopeptides small proteins involved in the blood-clotting process are suitable for reconstructing the phylogeny of recently evolved species, such as closely related mammals.
Such signalling devices are known to often evolve very rapidly, and even apparently at random (they can get bigger or smaller, more elaborate or more simple, and new features can appear or disappear) and Regaliceratops would seem to potentially fit that pattern having taken a sudden and dramatic divergence from its relatives.
"YPlan is going to evolve very significantly".
Traits with a high burden evolve very slowly.
