This has provided researchers with a unique evolutionary model for investigating stressful life underground.
Some species have a unique evolutionary lineage; others perform unusual or even irreplaceable functions in their ecosystems; and still others, such as the solenodons, are sui generis by almost any metric.
We also observe differential evolution of transcriptional regulation and a unique evolutionary role of channel regulators; crucially this is only observable in terms of the architecture plasticity potential.
The two trees exhibited the same topology, further supporting the hypothesis that strain 18323 is highly phylogenetically distinct from other B. pertussis strains, and might have been derived through a unique evolutionary process from the most recent common ancestor (MRCA 21,26.
We establish that a unique evolutionary stable strategy (ESS) for the population exists.
We also find that footprints reveal a unique evolutionary conservation pattern that differentiates functional footprinted bases from surrounding DNA.
In summary, we have elucidated the structures of the HBGA binding interface of the GI.8 BV that represents a unique evolutionary path selected by the host HBGAs.
The conclusion is that genomic, anatomical, and palaeontological evidence converges on a hypothesis in which arthropods and velvet worms are close relatives in an assemblage of molting animals that has a unique evolutionary origin.
