Interestingly, the Wnt signaling and cadherin-based adhesion functions of β-catenin have coexisted at least as far back as the origin of animals [1] (though C. elegans is a notable exception [2]), with coordination of these roles by a single protein perhaps facilitating evolution of the first multicellular organisms.
These included canalization, genetic assimilation and accommodation, gene environment interactions, epigenetic modification of DNA, gene duplication and genome evolution, serial homology, modularity, facilitated evolution, and the evolution of multicellularity.
The gait of the epaulette shark is convergently similar to those of tetrapods such as salamanders, suggesting that the movements needed for walking on land may predate, and facilitated the evolution of, the first terrestrial vertebrates.
The widespread interest in these two round (2R) genome duplications revolves around the possibility that the generation of thousands of new genes may have facilitated the evolution of the complex vertebrate body plan.
Computer simulations also demonstrated that this tends to generate smoother oscillatory dynamics than equivalent offspring numbers: it increases the probability of matching by facilitating rapid evolution of the parasite (data not shown).
The result is that the rate of environmental change interacts with the species' genetic architecture for the limiting trait to constrain or facilitate the evolution of the trait's heritability.
Functional redundancy of AVR genes within the genome may facilitate rapid evolution of the parasite to overcome host resistance by allowing elicitor genes to become inactivated without compromising parasite fitness [5], [37], [38].
Beyond facilitating the evolution of the long neck, the hypothesized bird-like respiratory apparatus offers additional advantages, emerging as the second key evolutionary innovation.
A recent study demonstrated that operons were often acquired with their regulators to facilitate the evolution of the transferred genes [ 55].
Before modern technology can facilitate an evolution of the usage of the Oxford Scores, the individual's scores need to be interpreted in a more meaningful way.
