Query: Minimal model for genome evolution and growth   Textual analysis of typical microbial genomes reveals that they have the
statistical characteristics of a DNA sequence of a much shorter length. This
peculiar property supports an evolutionary model in which a genome evolves by
random mutation but primarily grows by random segmental self-copying. That
genomes grew mostly by self-copying is consistent with the observation that
repeat sequences in all genomes are widespread and intragenomic and
intergenomic homologous genes are preponderance across all life forms. The
model predicates the coexistence of the two competing modes of evolution: the
gradual changes of classical Darwinism and the stochastic spurts envisioned in
``punctuated equilibrium''.
