Here we investigate the evolution of a most peculiar reproductive behaviour that occurs in simultaneously hermaphroditic land snails (Stylommatophora), the "shooting" of a so-called love-dart into the mating partner.
However, widely-used simulation programs cannot be easily tuned to precisely reproduce the peculiar evolution of a particular data set.
These results provide a phylogenetic framework and timescale with which to interpret the evolution of the peculiar morphological, developmental, and molecular features of turtles within the amniotes.
The characterization of Bacillus IGS-ETS, the first known for a phasmid insect, allowed us to infer about the variability and evolution of this peculiar tandemly-repeated system, and to compare it to the additional IGS-ETSs known to date in arthropods.
This suggests that some strong constraint is exerted on the evolution of these peculiar genes.
It would therefore seem reasonable to speculate that a genetic exchange between the theta replicons of the group D family (pAMβ1 family) and those of the group F family may have been responsible for the evolution of the peculiar pAMβ1 family replicons found in the B. cereus group.
This finding indicates that, despite phylogenetic distance and the evolution of peculiar molecular traits (Fig. 1 and 2), monocot and dicot MLO proteins are essentially conserved with respect to features involved in the interaction with PM pathogens.
But this war is of a peculiar nature.
"It's kind of a peculiar situation," Jacobs said.
