I think we can also surmise that the sphere is hollow, as
life is riding time, and time is not washing through a predetermined state of life, merely illuminating it - or is it?
There is a very interesting question here. In the outwardly expanding sphere (through time), new areas appear like great cavities in the sphere- or as blank canvases of the adaptive landscape. Eventually they will fill with genomes. The thing is the genomes do not spontaneously appear inside the space, they must, as genetics says
drift into it from the edges. This is an argument
against a force of life, and a potential pandoras box I wouldn't mind exploring. Could you argue that the adaptive landscape is the force?
But the idea of genetic drift is itself no entirely accurate. A better name would be genetic hopping. Each variant is a hop further along. This is not pure semantics, as in the race toward the centre of the empty cavity by the genome, those that can jump the further the fastest will get there first and can set up shop before the others.
Here's an extract from an
article on Jumping Genes - also called Transposons. Transposons are long portions of the genome that jump about from one section of the DNA strands to another, often causing deleterious effects to the organism.
"Transposons Are Not Always Destructive
Not all transposon jumping results in deleterious effects. In fact, transposons can drive the evolution of genomes by facilitating the translocation of genomic sequences, the shuffling of exons, and the repair of double-stranded breaks. Insertions and transposition can also alter gene regulatory regions and phenotypes. In the case of medaka fish, for instance, the Tol2 DNA transposon is directly linked to pigmentation. One highly inbred line of these fish was shown to have a variety of pigmentation patterns. In the members of this line in which the Tol2 transposon hopped out "cleanly" (i.e., without removing other parts of the genomic sequence), the fish were albino. But when Tol2 did not cleanly hop from the regulatory region, the result was a wide range of heritable pigmentation patterns (Koga et al., 2006).
The fact that transposable elements do not always excise perfectly and can take genomic sequences along for the ride has also resulted in a phenomenon scientists call exon shuffling. Exon shuffling results in the juxtaposition of two previously unrelated exons, usually by transposition, thereby potentially creating novel gene products (Moran et al., 1999).
The ability of transposons to increase genetic diversity, together with the ability of the genome to inhibit most TE activity, results in a balance that makes transposable elements an important part of evolution and gene regulation in all organisms that carry these sequences."
