Sentence examples for multiple evolutionary lineages from inspiring English sources

Shaded regions correspond to the phylogeographic groups discussed in the text, and their placement across major splitting events represents both current debates over the relationships of their constituent taxa as well as, in some cases, the likelihood that these convenient geo-temporal groups comprise members of multiple evolutionary lineages.

This mechanism has been traditionally considered less parsimonious, as it involves a complex ancestor and gene loss events occurring independently at multiple evolutionary lineages.

Similar to other studies (Nielsen et al. 2009; Campbell et al. 2012), we found no evidence for multiple evolutionary lineages in the Snake River, but local environments may influence their differentiation.

Multiple evolutionary lineages of E. coli O157 [ 8] with different lineages encoding variants of the H-antigen genes, and two distinct rfbE alleles within the O157-antigen biosynthesis gene cluster, have been described.

Finally, an approach using multiple gene phylogenies has firmly established that most host races of M. violaceum represent multiple independent evolutionary lineages, highly specialized on a single or a few host species [ 29].

Specific subsets of genes are more likely to be retained, including those 1) with higher expression levels (Seoighe and Wolfe 1999); 2) involved in environmental responses (Kondrashov et al. 2002); 3) present in multiple evolutionary divergent lineages (Gu et al. 2002) 4) that are functionally constrained (Davis and Petrov 2004) and 5) derived from whole-genome duplication (Hakes et al. 2007).

Genetically divergent populations of the copepod Tigriopus californicus provide an excellent model to look at the patterns of divergence among paralogs across multiple independent evolutionary lineages.

In our analysis, we focused on gene duplication events that occurred along multiple different evolutionary lineages, allowing for both retroposed and DNA-based duplications.

The remaining 6% of 2-d1 and 2-d2 isolates may represent one or multiple separate evolutionary lineages that have not been resolved, even with nine loci.

Conventionally, convergent changes refer to changes from different ancestral amino acids to the same descendant amino acid at a given position of a protein in multiple independent evolutionary lineages (Zhang and Kumar 1997; Nei and Kumar 2000).

In this research, the multiple cladogenic splits of evolutionary lineages (putative ecotypes) of the bacterium Bacillus simplex as an adaptational response to the microclimatically heterogeneous environment of "Evolution Canyon", Israel, are being studied [14] [17].
