Darwin himself intriguingly suggested that while there is a general evolutionary bias toward greater size, survival-of-the-fittest pressures on our ancestors, who were smaller than their primate competitors, may have led to the development of human intelligence.
The large size of the new species was unusual because there was a general evolutionary trend toward decreasing size in this and other theropod lineages closely related to birds.
There is a general evolutionary association between the number of precloacal and caudal vertebrae in snakes; however, there are various instances across the phylogenetic diversity of this group where this pattern is contradicted [ 30].
It is often assumed that increasing brain size was a general evolutionary trend in primates, yet recent fossil discoveries have documented brain size decreases in some lineages, raising the question of how general a trend there was for brains to increase in mass over evolutionary time.
It is worth emphasizing that we are not simply re-expressing the behaviour of the Tetrahymena chemical system in new language, but rather that we are positing that interpretation is a general evolutionary strategy operative from the molecular level upwards.> -wrap-foot> Datakenken from references [ 15- 18].
Future evolution studies will have to confirm whether this is a general evolutionary pathway for variants originating from the CBM4-2 scafford or if mutations distant from the binding-cleft also are, as they are for antibodies, capable of fine-tuning ligand-binder affinity.
Thus, organismal and genomic conflicts being the basis for major molecular innovations, which in turn might facilitate major evolutionary transitions, can be considered a general evolutionary principle.
Extensive DNA rearrangement of genic colinearity, as revealed by comparison of orthologous genomic regions, has been shown to be a general concept describing evolutionary dynamics of plant genomes.
This work exposes what may be a general feature of evolutionary conflicts fought by pathogen antagonists at host protein-protein interaction interfaces involved in immune signaling: the emergence of receptor-binding ligand epitopes capable of buffering amino acid variation.
Overall, our results suggest that particular invasive species may possess deterrent secondary chemistry, but it does not appear to be a general pattern resulting from evolutionary mismatches between exotic plants and native herbivores.
