It is likely that the acquisition of SsgB by an early actinomycete (before node 4 of Fig. 2) was a key to the later evolution of sporulation septation, but SALPs have been entirely lost independently from several subsequent branches.
Values of δ<1 can indicate temporally early evolution of a trait (i.e., adaptive radiation), while values of δ>1 indicate temporally later evolution of a trait (i.e., species-specific adaptation).
We also discuss an auroral event observed on day 140, which likely corresponds to the later evolution of a similar solar wind-induced storm, and track the evolution of the form over three HST orbits.
We also discuss the later evolution of a similar storm and show that the emission maps to the trailing region of an energetic neutral atom enhancement.
The athlete who finished our study (participation in the MRI at time point 5) but had to abort the race afterwards because of a hand phlegmonia has been counted as not aborting for our study since the cause for abortion was not related to a problem of the feet, and the measurements are thought to be independent of the later evolution of a hand phlegmonia.
In particular, the evolution of a rostrum might have been a key event leading to the later evolution of the acanthocephalan endoparasitism, given the enormous relevance of the proboscis for anchoring of the adults to the definitive hosts' intestinal wall.
Particularly the early evolution of a retractable anterior end might have represented a key event leading to the later evolution of the acanthocephalan endoparasitism, given the crucial role of the proboscis in the anchoring of adult acanthocephalans to the definitive hosts' intestinal wall [ 40].
In the case of evolutionary transitions, this allows us to separate the basic development involved in the origin of a new biological level from the later evolution of sophisticated developmental mechanisms for the "stabilization and maintenance of a new level of reproduction" (2000, 77).
In an extreme case, researchers planning trials could use this approach to produce a positive result from early survival experiences, ignoring the possible later evolution of the treatment effect.
The rapid radiation and diversification of angiosperms during the Cretaceous led to major ecological changes on the earth, the latter were a prerequisite for many critical evolutionary events [ 3] including the later evolution of human beings.
