Synonymous changes = mutations caused by genes selective environment. Mutated genomes are carried forward because they survive better in the environment. Mesoevolution: within a species, or within a population (ants, parallel evolutions within populations genetic or phenotypic level, repeated transitions from micro to meso produces convergence, they may also trigger adaptive radiations. In some ways it is, and in other ways it is absolutely not. See didacus valades, rhetorica christriana: aristotelian linear hierarchy of souls, drew first diagram that resembles a phylogeny. Evolution was the term used for development william harvey (1651: epigenesis organismal development as the successive differentiation (addition) of structures.
