The phrase "and the speciation between" is correct and usable in written English.
It can be used in discussions related to biology, ecology, or evolutionary studies when referring to the process of speciation and the distinctions between different species.
Example: "The research focused on the mechanisms of evolution and the speciation between various populations of the same species."
Alternatives: "and the differentiation among" or "and the formation of species between".
These replacements are not seen in SINEU-2_Gav, and thus they were generated after the speciation between crocodiles and gharials.
Considering a clock-like synonymous mutation rate of 0.68 × 10-9 substinutions/site/year in conifer genes based on pairwise comparisons of 3,723 spruce (Picea sitchensis) and pine (P. taeda) orthologues [ 28], the speciation between spruce and pine was estimated to have occurred ~147 million years ago (mya) and between section Trofoliae and section Pinus ~44 mya ago.
A study performed by Patterson and colleagues resulted in the most debatable issue on the speciation between human and chimpanzee (Patterson et al. 2006).
These accelerated evolution of the genes related to "transport" and "nuclear pore organization" might be involved in the speciation between S. cerevisiae and S. paradoxus.
This gene transfer probably predated the speciation between Liliopsida and core eudicotyledons for the concerned U{1 1} genes and is close to the root of the plant phylum for the group of U{1 1 1 1} genes.
In addition, another less obvious peak appeared from 0.7 to 0.8, which was responsible for the 3R event before the speciation between Brassica and Arabidopsis genomes.
The speciation between European and Central Asian wild apples likely occurred during Pleistocene repeated glaciations owing to the retreat and fragmentation of an ancient corridor of Tertiary temperate forests that ranged from the Atlantic Ocean to Bering (Juniper and Mabberley 2006).
In addition, among the non-primate mammal species, gene duplication events were confirmed occurring in ruminants before the speciation between Bos Taurus and Ovis aries [22].
Thus, a migration over the Beringian landbridge around 8 7.6 mya has likely been the starting point for the speciation between C. fiber and C. canadensis, each on a different continent (Fig. 1).
