    I've only just read about this "new" theory of "vanishing dimensions" however It has me wondering could we explain this phenomena and the universe' general development in evolutionary terms as the vanishing dimensions seems like it would have selective-adaptive properties?

    It may be this 2011 idea is already dead. Most new ideas of a drastic sort like this do not succeed. Let's check. Here is the paper:

    Detecting Vanishing Dimensions Via Primordial Gravitational Wave Astronomy
    Jonas R. Mureika, Dejan Stojkovic
    (Submitted on 16 Feb 2011)
    Lower-dimensionality at higher energies has manifold theoretical advantages as recently pointed out. Moreover, it appears that experimental evidence may already exists for it - a statistically significant planar alignment of events with energies higher than TeV has been observed in some earlier cosmic ray experiments. We propose a robust and independent test for this new paradigm. Since (2+1)-dimensional spacetimes have no gravitational degrees of freedom, gravity waves cannot be produced in that epoch. This places a universal maximum frequency at which primordial waves can propagate, marked by the transition between dimensions. We show that this cut-off frequency may be accessible to future gravitational wave detectors such as LISA.
    5 pages. Somewhat expanded version with discussions that could not fit into the PRL version; references added

    The only other paper on arXiv by these two authors is a reply to a Comment on their main paper:

    The "Comment on: Detecting Vanishing Dimensions Via Primordial Gravitational Wave Astronomy" [arXiv:1104.1223] is misleading and premised on a misinterpretation of the main content of Phys. Rev. Lett. 106, 101101 (2011) [arXiv:1102.3434]. The main claim in the comment - that in some exotic theories different from general relativity (GR) there might be local degrees of freedom even in lower dimensional spaces - is trivial. Nevertheless, the authors of the Comment fail to come-up with a single self-consistent example. This claim, however, has no implications for our paper, in which we make it clear we are working within the framework of "vanishing" or "evolving" dimensions as defined in arXiv:1003.5914.
