Three major revolutions in bacterial cell surface structure and molecular biology stand out as being especially far-reaching in their impact on the progressive evolution and diversification of life.
Genes maintained following duplication are subject to progressive divergence, providing the opportunity for diversification of the gene repertoire.
Scientifically, Darwin's use of the term value was surprising because he, unlike Lamarck, did not believe that evolution was progressive, nor did he think that evolutionary diversification was driven solely by natural selection.
Progressive long-term salinity change appears to have promoted the diversification of bacterioplankton communities by modifying the composition of ancestral communities and by allowing the establishment of new taxa [ 101].
Despite the explosion of tree-like diagrams in the recent biological literature, evolution is indeed often perceived as a linear, progressive process rather than as a story of unceasing branching and diversification ultimately resulting in a tree.
Using longitudinal samples collected form a subset of these patients a pattern of initial bacterial community diversification was observed in younger patients compared with a progressive loss of diversity over time in older patients.
In anticipation, the West Virginia Center for Budget and Policy, a progressive think tank, has called for using natural-resources taxes to create a "future fund" that would promote diversification by investing in infrastructure, education, and job-training programs.
