The various colors and hatchings represent different paths of protostellar evolution: P1 denotes a Kelvin-Helmholtz contracting protostar, P1hd a halo in which HD cooling was activated, P2 an oscillating protostar, and P3 and P3p super-giant protostars.
We assume that we observe only the endpoints of k different paths of X t) depending on the evolution branch.
In all, the simulation suggests a cancer cell gains most by silencing a highly connected gene, as a it explores different paths of random variation in its evolution and naturally selects the path that leads to a faster entropy increase (Kaila and Annila 2008).
"[T]he differences in technology and culture between the two areas are very strong, showing the people of the two regions chose very different paths to the evolution of technology and society," Villa said.
Dr. Villa said the contrasting cultures between these people and those who arrived in Europe about this time, leaving graphic traces on cave walls, showed that "the two regions chose very different paths to the evolution of technology and society".
Finally, we suggest that the NHX and SOS1 families represent examples of two different paths in the molecular evolution of stress tolerance.
When this is complete, we will have a more complete view of how mutations of different types impact different paths and patterns in evolution.
Why did evolution take different paths to get to similar places (parental care, for example)?
This shows that even in central metabolism that the path of evolution is not a straight forward walk but involves different paths in specific sequences.
