Sentence examples for rate of origination from inspiring English sources
"Comparative genomics reveals a constant rate of origination and convergent acquisition of functional retrogenes in Drosophila".
However, this high rate of origination was offset by low genetic isolation, and lower F1 hybrid fertility increased the evolutionary independence of derived populations.
Due to the 27 Myr peak, we divided the "intensity" previously defined by the stratigraphic interval length to get a "fractional rate" of origination or extinction.
Using fossil data alone there is a suggestion of a slow-down in the net rate of origination that is not significant, mirroring the insect fossil record as a whole [ 4].
The rate of origination, u, of the junk genes might be much larger than that for beneficial genes, so that the total pan-genome would become very large, but the pan-genome of beneficial genes would remain comparable to the single genome size (as it is in Figure 2 for the simulation where all genes are beneficial and u is small).
This model further assumes that TFBSs in the genomic region of interest have a constant rate of origination λ and decay exponentially with a relative rate μ (supplementary fig. S1, Supplementary Material online) and is mathematically identical to the classical model of queuing theory called M/M/∞ (Medhi 2003).
The rates of origination and extinction of species shape the history of life.
To understand whether an event is really unusual, paleontologists can chart rates of origination and extinction for the intervals of time preceding and following the event in question.
Low volatility groups have low rates of origination and extinction, leading to a stable clade made up of the same species over long periods of time.
Volatility is defined in the exercise as a measure of a group's stability through time and, therefore, as a function of background rates of origination and extinction.
Building on that finding, one team member, earth scientist James Kirchner at the University of California, Berkeley, decided to compare rates of extinction to rates of origination over a 500-million-year period.
